In this example, standard mode working requires the use of two PLCs, a discrete input module, a BMX NOM 0200 module, and 2 SR2MOD01 modems.
First Slave PLC Wiring
The first slave PLC is connected as following:
In this example, the first modem is connected to the processor serial port of the first slave PLC.
The actuator state controls the Start variable state in the application.
Second Slave PLC Wiring
The second slave PLC is connected as following:
In this example, the second modem is connected to the channel 0 of the BMX NOM 0200 module of the second slave PLC.
For a better communication reliability, the cable TCS XCN 3M4F3S4 is used for DTR/DSR/DCD modem signals handling by the application.
