The Communication and Control Processor for the CLM is the Honeywell 51402426-100 CCP PWA.
The Communication Link Module (CLM) provides a method of economically connecting various RS-232 and 485 based devices to your Honeywell TPS system.
The CLM runs under a modified Application Module (AM) software personality. The hardware is similar to AM hardware, contained in a standard TPN Five-Slot or dual-node equipment module that supports the Local Control Network (LCN). In the CLM, the following boards and their appropriate input /output (I/O) boards are used to provide serial communication ports to RS-232 and RS-485 devices.
