This module is used for the interface sending APB remote signal. The combination of APB PLC and APB communication module can get networking function, which makes multiple APBs become a network with RS-485 bus, and have real-time monitoring on one HMI with MODBUS communication protocol. The user will enjoy more flexibility when designing automation solution.
