Appendix B
Total Connections Required by the Soft1 Controller
This table calculates the connections used in this example.
The remote 1756-CNB and 1788-CNC card are configured as ‘none’ for the
communication format, so the SoftLogix controller would require a direct
connection for any I/O modules connected to these devices that you want in the
configuration for the SoftLogix controller.
