through the Configuration port allows remote access to the controller via the Control Builder and User
Utility programs. This will enable trouble shooting, configuration changes and firmware upgrade.
The optional communications board adds two bi-directional, multi-drop RS 485 serial communication
interfaces to the controller CPU module. The COMM A port uses Modbus RTU protocol and is a
master/slave link allowing up to 31 controllers to be connected to a single host computer. The computer
initiates all communication. COMM B port allows the controller to operate as a master device to up to 16
slave Modbus compatible devices. Data transferred through this port is integrated into the user’s control
strategy through read and write function blocks. Applications might include writing controller data (set
points, process variables, etc.) to a strip chart recorder to produce a hard copy of process performance, or to
read data from other controllers.
