Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively according to setting of controller.
PM-B communication driver’s read schedule
Read schedule setting parameters are as follows:
1) STATION – station number of PM-B controller.
2) Read memory type – memory = D( analog ), X ( digital ). (refer to <Table 1> ~ <Table 2> )
3) Read start address – start reading address in memory.
4) Save Start Address for Communication Server – Input save start address of communication server.
5) Read Size – word unit read size.
