Note Only one CPM1A-TS002/TS102 Temperature Sensor Unit can be connected to the CPU Unit. If a CPM1A-TS002/102 is connected to the CPU Unit, only one additional Expansion Unit (other than a CPM1A-TS002/102) or one Expansion I/O Unit can be connected to the CPU Unit.

1-2-3 Host Link Communications

Host Link communications which allows up to 32 OMRON PCs to be controlled from a host computer. The computer-PC connections can be made connectors such as RS-232C and RS-422 Adapters.

One-to-one Communications The following diagram shows the possible methods for a 1:1 connection between a CPM1A and an IBM PC/AT or compatible computer.
