CPM1A-SRT21
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.
