Processor modules provide all processing, I/O scanning, logic, communications functions required in any of the RTU configurations that may be applied. The I/O controller / processor module has up to three independent communications ports. Ports 2 and 3 can use plug-in option boards while port 1 is fixed as RS232C. CP-30 port 1 is 10/100 Ethernet port. RTUs may have up to 2 CP-11 modules that can serve up to four backplanes in a hot standby configuration (note: one processor should be in an odd numbered backplane slot and the other in an even numbered backplane slot). One processor controls I/O module scanning and communications while the other redundant process or listens.
