1:1 Links
With a 1:1 link, two CPM1As or a CPM1A and CQM1 or C200H# are connected 1:1 with one side as the Master and the other as the Slave to
provide an I/O link of a maximum of 256 points (LR 0000 to LR 1515).
Example of a 1:1 Link between CPM1As
Limitations of the CPM1A 1:1 Link
CPM1A I/O links are limited to 16 words (LR 00 to LR 15). Therefore, use these 16 words (LR 00 to LR 15) on the CQM1 or C200H# side when
forming 1:1 links with a CQM1 or C200H#.
NT Links
High-speed communications can be achieved by providing a direct access through the use of the NT Link between the CPM1A and
Programmable Terminal.
