3-4-6 Peripheral Device Connection

The CPM1A CPU Unit can be connected to a C200H-PRO27-E Programming Console with a standard C200H-CN222 (2 m) or C200H-CN422 (4 m) Connect- ing Cable. The CPM1A CPU Unit can be also connected to a CQM1-PRO01-E. The CQM1-PRO01-E is provided with a 2-m Connecting Cable.

3-4-7 Host Link Connections

One-to-one Host Link Connection

Host Link is a command/response communications system in which commands are transmitted from the host computer and corresponding responses are returned from the destination PCs. Host Link commands can be used to read/ write data in PC data areas and read/write PC settings.

The CPM1A CPU Unit can be connected to an IBM PC/AT compatible computer or a Programmable Terminal with an RS-232C Adapter, as shown in the follow- ing diagram.
