(2) Digital IO monitor (read only)
(a) IO pin status
Address Content Data length
0x0204 The ON/OFF status of DI and DO. The pin location is as follows. 1word
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 Bit No.
DI8 DI7 DI6 DI5 DI4 DI3 DI2 DI1 Signal name
Bit15 Bit14 Bit13 Bit12 Bit11 Bit10 Bit9 Bit8 Bit No.
DI12 DI11 DI10 DI9 Signal name
Note: The status of digital IO is integrated status of DI source, control switch (PD16) and communications source (PD25),
please see the following samples.
External hardware terminal DI12~DI1 represented by bit11~bit0.
Bit binary for description :bit11~bit0 represent DI12~DI1 (left to right)
Digital input contact source switch(PD16) : 111111000000
External hardware terminal status: 111100001111 (1 represent ON
，
0 represent OFF)
Communication control digital input contact status (PD25) : 111000111000
Based on the above, The status of digital IO (address 0x0204),and the pin DI12~DI7 are determined by communications
source (PD25) status and the pin DI6~DI1 are determined by External hardware terminal status.
So the final digital IO status (address 0x0204) is 111000 001111.
Address Content Data length
0x0205 The ON/OFF status of DI and DO. The pin location is as follows. 1word
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 Bit No.
DO6 DO5 DO4 DO3 DO2 DO1 Signal name
(b) IO pin function
Address Content Data length
0x0206~0x020D To display the pin function programmed of DI and DO 1word
Attention: If the input/output signal function is not suitable for current control mode, then send back 0.
Ex : If it is in speed control mode, PD07=0x000B, then bit0~bit7 of Address 0x0208 must send back 0.
Address : 0x0206
Bit8~Bit15 Bit0~bit7 Bit No.
DI1 DI2 Signal name
0x00~0x2F 0x00~0x2F Function
Address : 0x0207
Bit8~Bit15 Bit0~bit7 Bit No.
DI3 DI4 Signal name
0x00~0x2F 0x00~0x2F Function
Address : 0x0208

DI7 D8 Signal name
0x00~0x2F 0x00~0x2F Function
Address : 0x020A
Bit8~Bit15 Bit0~bit7 Bit No.
DI9 D10 Signal name
