Smart AC module includes four voltage inputs (U1, U2, U3, U4) and four current inputs (I1, I2, I3, I4) and MCU processing subsystem , CAN controller. Wherein the voltage , the current in the power calculations are associated pairwise , the U1 and I1, U2 and I2, U3 and I3, U4 and I4 are internally associated with power . For example : When the wiring is formed power / energy for the two -table method , U1 then Uab, I1 then Ia, U2 pick Ubc, I2 then Ic, and set the power of both groups and to the MMI; When wiring is three when forming a power / energy meter method , U1 then Ua, I1 then Ia, U2 pick Ub, I2 then Ib, U3 pick Uc, I3 then Ic, and set the power of the three groups on the MMI and can be. Sum and other tasks can be completed to the host computer system .
Smart AC module AC-I, AC-U and AC performance measurement differences were only 8 current , input voltage 8 is otherwise the same .
Different configurations / Wiring Smart AC modules mainly for the selection of the power group , which involves the calculation of power / energy. This selection is made by setting value to achieve, namely, different wiring sub- module hardware unchanged. Since the sub-module can be set for the basic power U1 * I1 ( correct expression should : vector { U} { multiplying the conjugate vector of I }, where , for simplicity , writing U1 * I1, the same below ) , U2 * I2, U3 * I3, U4 * I4, and therefore the power pack voltage terminal wiring identified , corresponding current terminal wiring also determined. Each input can be generated corresponding to the effective value of the voltage or current , and each can produce a corresponding input power, power factor, and energy. Power , power factor and energy group number is determined by the appropriate wiring . The power of the group is configured by setting the AC input module type items to carry , the value in the range of : 0-5 , meaning the values shown in Table 3-2-1 :

2) MMI system
Core interactive (MMI) system is a bus not chip microcontroller, and its main function is to display the keyboard on the device status information , scan panel and real-time transmission to the CPU. So the CPU is concerned , MMI is the equivalent of one of its peripherals. Communication between the CPU and the MMI through the SPI interface , the communication rates up to 2Mb / s, and has a high degree of reliability . Using this configuration , both to avoid a large amount of CPU bus outer lead , to improve the reliability of the device , and hardly increase the cost and enhance the cost performance of the device.
Display window on the plug-in uses four lines , twelve characters per line LCD display , HMI lucid, PS Series protection device configured to common keyboard operation, making the man-machine dialogue operation convenient and simple .
3.4 Power Module (POWER)
The DC inverter power module plug-ins . 220V or 110V DC voltage input after interference filter circuit , the use of the principle of inverter output this device requires four sets of DC voltage, ie 5V, ± 12V, 24V (1) and 24V (2). 5V and ± 12V voltage common , they are with 24V (1) and 24V (2) among the three are not mutually common ground , and the use of floating mode , not connected with the case.
The output voltage of each system uses:
a) 5V power supply for use in the work of each processor systems ;
b) ± 12V power supply is used to simulate the working system ;
d) 24V (1) for driving the power supply and signal output relay ;
e) 24V (2) open into the external power source is used .
To enhance the anti-jamming capability of the power supply module , the module 's DC input terminal of the 24V power supply and leads are installed filters.
5,6 terminal of the power supply module for the device empty contact output signal disappears .
3.5 Intelligent digital input module (DI)
Function digital input modules include : digital inputs , encoder inputs, pulse inputs . Specifically, the switch input can be collected : switch position , switch position , [ tap position ] , a variety of actions to protect the safety device alarm signal , other public signals. Encoded input can be collected : level information, [ tap position ] and so on. Pulse inputs can be collected : active power forward , reverse active power , reactive power forward , reverse reactive power .
It should be noted that we allow the encoded input , but do not need the device lockout slide file processing, tap position and other information can also be entered as a class uploading satisfied with the switch , the above system formed by the host state in accordance with the letter of the remote connector locations and other information.
Enter code here can actually allow access to four formats : ① single- mode input contacts , output value of the input signal into the amount of contact closure of the opening number, 1 is the lowest value , row number first, due to the number of terminals by limit , its value is generally not more than 20; ② to BCD code input , LSB first , its value is limited to 99999; ③ to HEX code input , LSB first , its value is limited 0xFFFFF; ④ in binary code input , low first , in front of tens of bits , followed by (less than ten ) to carry, and its value is limited to 99; ⑤ allows the first anti- coded in any format is a single contact point the way to resolve remote signal output.
Each has its own all the input filter time constant ( or called debounce time , stabilization time ) , you can set the range 0ms ~ 9999ms, in steps of 1ms. The setting value of the maximum possible rate of change signal and minimal changes in time , generally switch can be set to 15ms, for some operating circuit disconnection signal , as the signal may produce short break when switching division , so the filter time depending on the circumstances Let a little longer, as 1000ms. Switch can be set to the amount of general state ( no SOE) and SOE ( state amount of information but also a ) two. Similarly, for each input attributes for each DI modules incorporate several of our recommendations we give a typical configuration mode , although you can have a variety of configurations on principle . Special configuration requirements can be given in the ordering .
The module has 20 inputs, divided into two groups : the former group has 16 inputs and corresponding common negative side , tend to collect on the main switch , coded signals ; latter group has 4 inputs and corresponding common negative side , the main tend to pulse volume collection . This two common negative terminal can be connected to each other , each with its own 24V power supply, but also a power source , such as the device provides a 24V (2) power supplies.
Each input can be set with the following characteristics: filter time constant (FT), whether as a sequence of events (SOE) sent as pulse inputs or digital inputs or encoder input , such as whether the state negated . Configuration of the digital inputs mainly through setting the digital input module type items to carry , the value ranges are: 0 to 10 , meaning the values shown in Table 3-5. When the digital input module type is non- zero, then the value of the fixed term of no value , but the device software automatically fills in the appropriate value based on the significance of this type of value, and again when the transfer value can be seen to be type value content ; when the digital input module type is 0 ie, user-defined types, the value will be used subsequently fixed value of the item , that item is then determined by the value determined in accordance with user needs , these settings are defined the characteristics of the signal input of each channel : each include an attribute byte and a digital filter time constant . In order to reduce the number of value items , the two properties into a single byte value item number preceding the opening into its properties in the low byte , the entire value of the item given input hexadecimal format and filter time constants representing a fixed value of the item , enter the decimal mode .
(I) digital input module input signal value of the attribute byte ( referred Attr) meaning you Table 3-5-1 :
The value in hexadecimal input , bit7 ~ 0 is an attribute definition signal input , bit15 ~ 8 is an attribute definition signal input terminal , the signal input here, including all remote signal inputs, encode input and pulse volume input so that the modules are required for all signal input terminals are defined . To bit0 ~ 7 illustrate:
① bit2 ~ 0 define whether the formation of SOE information, whether the formation of the accident total / bell bit , notice whether the formation of total / electric flute bit :
bit0 ( notice the total / electric flute bits ) = 1 for this bit Remote Communication module introduced in the case of a terminal , then the total rises notice / electric flute bits, set the first 21 telesignalling 1 ; pair DIO mode piece is set to a remote signal 12 . Soon total / electric flute bit can only be cleared by reset signal .
bit1 ( total accident / bell bit ) = 1 for this bit Remote Communication module introduced in the case of a terminal , then raised a total accident / bell bits, set 22 telesignalling 1 ; pair DIO module is section 13 is set to a remote signal . Total accident / bell bit is only to be cleared by reset signal . bit2 (SOE form bit ) = 1, within the module corresponds to the actual terminal number ( from 0 Number ) code of SOE to send the form , usually in this way , which is usually set bit2 = 1;
When the pulse input signal terminal behind the definition of the terminal letters are still away , its front SOE code number to be considered occupied pulse input terminal number, the code number that SOE always correspond with the actual pin number , which is sandwiched with the Pulse independent of input terminals , it is necessary to know the background of the system data definition .
② bit5 1-3 define the nature of the input signal :
= 1 ( ie bit5 = 0, bit4 = 0, bit3 = 1) , the signal terminal input signal is encoded input , such as the single contact mode , BCD code input , HEX code input and binary code input , the specific encoding another by the value set ;
= 3 ( ie bit5 = 0, bit4 = 1, bit3 = 1) when the input signal is a pulse signal terminal input ;
= 4 ( ie bit5 = 1, bit4 = 0, bit3 = 0) , the signal input terminal as an ordinary remote signal input , usually also define them as SOE, namely bit0 ~ 2 = 4;
③ bit7 define whether the input signal status negated :
= 0 is not negated. At this time when the input contact signal is disconnected, or that open into the terminal without 24V + points Pops, the program assumes that the status is 1. When the input signal contacts are closed , or that open into the terminal has 24V + , the program assumes that the status value of 0 ;
= 1:00 negated. At this time when the input contact signal is disconnected, or that open into the terminal without 24V + points Pops, the program assumes that the status is 0. When the input signal contacts are closed , or that open into the terminal has 24V + , the program assumes that the status is 1. For SAI-908 This module is usually taken bit7 = 1;
For the attribute byte Attr, common values are:
Remote signal input : = 0xA4; ( Note : 0x indicates a hexadecimal value thereafter )
Coding input : = 0x88;
Pulse Input : = 0x98.
(Ii) the digital input module input signal filter time constant (or debounce time ) value ( referred to as FT):
The value entered in decimal seconds , input range from 0 to 9.999 seconds . Each has its own signal input of FT.
(Iii) digital input module encoded input about the value :

= 12: Binary input is similar , but the ten -bit value 0 telesignalling not connected ( access order of bits 0,1 ...... 9 , ten 1,2 ...... ) , when the whole of the ten points telesignalling , the software will think ten value 0 ; this method is mainly used to save a remote signal input, such as 11 -bit code into the remote signal input DIO module 1 to 19 files can be expressed transformer tap .
= 13: Binary input ; access order of bits 0,1 ...... 9 ...... ten 0,1 . When unusual circumstances that ten telesignalling are all sharing software will consider a value of ten .
Note : = 0 to 3 : Only sent coded values ;
= 4 to 7 : the only way to send the letter away , do not send coded values , coded values calculated by the background itself ;
= 8 to 13: while sending coded values and the way of remote communication .
Which specific segment values ( below referred to as " the way to send coded " ) with the host computer system can identify what data about or need . When there are multiple encoded input , the only way to send the first encoding type is determined by the encoding. A child the same value on all modules to send coded manner , and with the first encoding type definitions prevail.
③ encoding n starting serial number : the lowest level of the encoded signal input terminal number, the numbers from one number , not the number of common encounter . Encoded LSB first , that a small number of terminals . Enter the decimal value .
④ occupy open into several encoding n : number of signal terminals occupied, is not common , fixed values in decimal input.

2) MMI system
Core interactive (MMI) system is a bus not chip microcontroller, and its main function is to display the keyboard on the device status information , scan panel and real-time transmission to the CPU. So the CPU is concerned , MMI is the equivalent of one of its peripherals. Communication between the CPU and the MMI through the SPI interface , the communication rates up to 2Mb / s, and has a high degree of reliability . Using this configuration , both to avoid a large amount of CPU bus outer lead , to improve the reliability of the device , and hardly increase the cost and enhance the cost performance of the device.
Display window on the plug-in uses four lines , twelve characters per line LCD display , HMI lucid, PS Series protection device configured to common keyboard operation, making the man-machine dialogue operation convenient and simple .
3.4 Power Module (POWER)
The DC inverter power module plug-ins . 220V or 110V DC voltage input after interference filter circuit , the use of the principle of inverter output this device requires four sets of DC voltage, ie 5V, ± 12V, 24V (1) and 24V (2). 5V and ± 12V voltage common , they are with 24V (1) and 24V (2) among the three are not mutually common ground , and the use of floating mode , not connected with the case.
The output voltage of each system uses:
a) 5V power supply for use in the work of each processor systems ;
b) ± 12V power supply is used to simulate the working system ;
d) 24V (1) for driving the power supply and signal output relay ;
e) 24V (2) open into the external power source is used .
To enhance the anti-jamming capability of the power supply module , the module 's DC input terminal of the 24V power supply and leads are installed filters.
5,6 terminal of the power supply module for the device empty contact output signal disappears .
3.5 Intelligent digital input module (DI)
Function digital input modules include : digital inputs , encoder inputs, pulse inputs . Specifically, the switch input can be collected : switch position , switch position , [ tap position ] , a variety of actions to protect the safety device alarm signal , other public signals. Encoded input can be collected : level information, [ tap position ] and so on. Pulse inputs can be collected : active power forward , reverse active power , reactive power forward , reverse reactive power .
It should be noted that we allow the encoded input , but do not need the device lockout slide file processing, tap position and other information can also be entered as a class uploading satisfied with the switch , the above system formed by the host state in accordance with the letter of the remote connector locations and other information.
Enter code here can actually allow access to four formats : ① single- mode input contacts , output value of the input signal into the amount of contact closure of the opening number, 1 is the lowest value , row number first, due to the number of terminals by limit , its value is generally not more than 20; ② to BCD code input , LSB first , its value is limited to 99999; ③ to HEX code input , LSB first , its value is limited 0xFFFFF; ④ in binary code input , low first , in front of tens of bits , followed by (less than ten ) to carry, and its value is limited to 99; ⑤ allows the first anti- coded in any format is a single contact point the way to resolve remote signal output.
Each has its own all the input filter time constant ( or called debounce time , stabilization time ) , you can set the range 0ms ~ 9999ms, in steps of 1ms. The setting value of the maximum possible rate of change signal and minimal changes in time , generally switch can be set to 15ms, for some operating circuit disconnection signal , as the signal may produce short break when switching division , so the filter time depending on the circumstances Let a little longer, as 1000ms. Switch can be set to the amount of general state ( no SOE) and SOE ( state amount of information but also a ) two. Similarly, for each input attributes for each DI modules incorporate several of our recommendations we give a typical configuration mode , although you can have a variety of configurations on principle . Special configuration requirements can be given in the ordering .
The module has 20 inputs, divided into two groups : the former group has 16 inputs and corresponding common negative side , tend to collect on the main switch , coded signals ; latter group has 4 inputs and corresponding common negative side , the main tend to pulse volume collection . This two common negative terminal can be connected to each other , each with its own 24V power supply, but also a power source , such as the device provides a 24V (2) power supplies.
Each input can be set with the following characteristics: filter time constant (FT), whether as a sequence of events (SOE) sent as pulse inputs or digital inputs or encoder input , such as whether the state negated . Configuration of the digital inputs mainly through setting the digital input module type items to carry , the value ranges are: 0 to 10 , meaning the values shown in Table 3-5. When the digital input module type is non- zero, then the value of the fixed term of no value , but the device software automatically fills in the appropriate value based on the significance of this type of value, and again when the transfer value can be seen to be type value content ; when the digital input module type is 0 ie, user-defined types, the value will be used subsequently fixed value of the item , that item is then determined by the value determined in accordance with user needs , these settings are defined the characteristics of the signal input of each channel : each include an attribute byte and a digital filter time constant . In order to reduce the number of value items , the two properties into a single byte value item number preceding the opening into its properties in the low byte , the entire value of the item given input hexadecimal format and filter time constants representing a fixed value of the item , enter the decimal mode .

bit0 ( notice the total / electric flute bits ) = 1 for this bit Remote Communication module introduced in the case of a terminal , then the total rises notice / electric flute bits, set the first 21 telesignalling 1 ; pair DIO mode piece is set to a remote signal 12 . Soon total / electric flute bit can only be cleared by reset signal .
bit1 ( total accident / bell bit ) = 1 for this bit Remote Communication module introduced in the case of a terminal , then raised a total accident / bell bits, set 22 telesignalling 1 ; pair DIO module is section 13 is set to a remote signal . Total accident / bell bit is only to be cleared by reset signal . bit2 (SOE form bit ) = 1, within the module corresponds to the actual terminal number ( from 0 Number ) code of SOE to send the form , usually in this way , which is usually set bit2 = 1;
When the pulse input signal terminal behind the definition of the terminal letters are still away , its front SOE code number to be considered occupied pulse input terminal number, the code number that SOE always correspond with the actual pin number , which is sandwiched with the Pulse independent of input terminals , it is necessary to know the background of the system data definition .
② bit5 1-3 define the nature of the input signal :
= 1 ( ie bit5 = 0, bit4 = 0, bit3 = 1) , the signal terminal input signal is encoded input , such as the single contact mode , BCD code input , HEX code input and binary code input , the specific encoding another by the value set ;
= 3 ( ie bit5 = 0, bit4 = 1, bit3 = 1) when the input signal is a pulse signal terminal input ;
= 4 ( ie bit5 = 1, bit4 = 0, bit3 = 0) , the signal input terminal as an ordinary remote signal input , usually also define them as SOE, namely bit0 ~ 2 = 4;
③ bit7 define whether the input signal status negated :
= 0 is not negated. At this time when the input contact signal is disconnected, or that open into the terminal without 24V + points Pops, the program assumes that the status is 1. When the input signal contacts are closed , or that open into the terminal has 24V + , the program assumes that the status value of 0 ;
= 1:00 negated. At this time when the input contact signal is disconnected, or that open into the terminal without 24V + points Pops, the program assumes that the status is 0. When the input signal contacts are closed , or that open into the terminal has 24V + , the program assumes that the status is 1. For SAI-908 This module is usually taken bit7 = 1;
For the attribute byte Attr, common values are:
Remote signal input : = 0xA4; ( Note : 0x indicates a hexadecimal value thereafter )
Coding input : = 0x88;
Pulse Input : = 0x98.
(Ii) the digital input module input signal filter time constant (or debounce time ) value ( referred to as FT):
The value entered in decimal seconds , input range from 0 to 9.999 seconds . Each has its own signal input of FT.
(Iii) digital input module encoded input about the value :
Enter the total number of items ① encoding value : Define the number of modules coded decimal input value ;
② encoding n type setting :
= 0,4 or 8 : Single contact mode ;
= 1,5 or 9: BCD code input ;
= 2,6 or 10: HEX code input ;
= 3,7 or 11 : Binary input ; access order of bits 0,1 ...... 9 ...... ten 0,1 . When unusual circumstances that ten telesignalling are all sharing software will think ten value 0 ;
= 12: Binary input is similar , but the ten -bit value 0 telesignalling not connected ( access order of bits 0,1 ...... 9 , ten 1,2 ...... ) , when the whole of the ten points telesignalling , the software will think ten value 0 ; this method is mainly used to save a remote signal input, such as 11 -bit code into the remote signal input DIO module 1 to 19 files can be expressed transformer tap .
= 13: Binary input ; access order of bits 0,1 ...... 9 ...... ten 0,1 . When unusual circumstances that ten telesignalling are all sharing software will consider a value of ten .
Note : = 0 to 3 : Only sent coded values ;
= 4 to 7 : the only way to send the letter away , do not send coded values , coded values calculated by the background itself ;
= 8 to 13: while sending coded values and the way of remote communication .
Which specific segment values ( below referred to as " the way to send coded " ) with the host computer system can identify what data about or need . When there are multiple encoded input , the only way to send the first encoding type is determined by the encoding. A child the same value on all modules to send coded manner , and with the first encoding type definitions prevail.
③ encoding n starting serial number : the lowest level of the encoded signal input terminal number, the numbers from one number , not the number of common encounter . Encoded LSB first , that a small number of terminals . Enter the decimal value .
④ occupy open into several encoding n : number of signal terminals occupied, is not common , fixed values in decimal input.
