Device part of RM-110 POWER METER input Com Port(COM1), Baud Rate(1200~9600 BPS), Parity Bit(2), Data Bit(7), Stop Bit(1) respectively.
In case of 485 communication, you have to do write TxRTS(or TxON), RxECHO(or RxON), etc, in order to not receive echo signal.
Station, baud rate, etc of RM-110 are set by setting switch attached at power meter.
RM-110 read schedule
Read schedule setting parameters are as follows:
1) Station - station number of controller.
2) Read function number - 08, 11, 15, 1A, 20.
3) Read Start Address.
4) Save Start Address for Communication Server - Position of ScanBuf to save the read value.
5) Read Size - 1~15 word 20 command(Reading all DATA) is fixed as 20 word.

Digital Write
Digital write setting parameters are as follows :
1) PORT : Connected PORT number.
2) STATION : STATION number of RM-110.
3) ADDRESS : In case of 54 command(01 : MDA RESET or 02 : Mvo RESET).
4) EXTRA1 : Command 54 : DATA RESET or 55 : RESET all type.
Write example)
PORT : 0 STATION : 1 ADDRESS:0001 EXTRA1:54
If you set as above, you can do MDA RESET.
Analog Write
There is no analog output of RM-110 POWER METER.
