PLC communication is a vital part of any control system. Optional communication/networking modules allow the BRX controller to easily share data with other devices or control remote systems. BRX serial communications modules provide up to (4) additional serial ports for any BRX PLC unit.
Today's PLCs need to communicate to numerous industrial devices including remote I/O, motor drives, servo controllers, operator interfaces, and oftentimes server-level PCs running various manufacturing related applications. These devices can all use different connection strategies and different communication protocols. Therefore, it's vital for machine builders and other users to install PLCs that can seamlessly connect with existing older networks as well as new ones, since each installation site can have very different communication needs.
The BRX PLC/CPU has several communications ports built-in, plus an optional POM slot. These ports support an assortment of industrial protocols including Modbus, EtherNet/IP, and MQTT. For most applications, the communication ports provided by the PLC/CPU is sufficient. To add capability or capacity, serial expansion modules are available to add up to 4 RS-422 or RS-232 serial ports.
