PM-170E communication driver’s read schedule
Read schedule setting parameters are as follows:
1) STATION – station number of PM-170 or PM-130E/PM-130P.
2) Read table number – table number = 1, 2, 9, 10. (refer to <Table 1> ~ <Table 4> )
3) Read start address – start reading address in table.
4) Save Start Address for Communication Server – Input save start address of communication server.
5) Read Size – word unit read size.

PM-170E controller support ASCII, Modbus ( or DNP 3.0 of PM-130E model ) protocol.
PM-170E communication driver support Modbus protocol. So you have to set 'bin' mode at CoP setting menu. ( 'rtu' mode at Prot menu for PM-130E )
Note) PM-130E model is the termination resistor is needed. Also PM-130E model don't exist table number 2.

You can set PM-170E controller by using write settings.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION station number of PM-170 or PM-130E/PM-130P.
3) ADDRESS writing address in table number.
4) Extra1 Writing table number = 1, 2, 9, 10.
5) Extra2 Don't care.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION station number of PM-170 or PM-130E/PM-130P.
3) ADDRESS writing address in table number.
4) Extra1 Writing table number = 1, 2, 9, 10.
5) Extra2 Don't care.
Write example 1)
PORT:0, station:1, ADDRESS:0015, Extra1: 2, Extra2 :
The setting parameter shown above is setting example for 15 address, 2 Table number.
