Point-to-Point Discrete Operation

The following illustrates an example of a point-to-point discrete system. The “Contact Closure Input” may be as simple as a bare wire or be connected to an output of an I/O module. This is an example of turning a lamp at the Master unit by closing a contact at the Remote unit using a discrete output.

Point-to-point discrete operations are bi-directional. An input on the Remote will activate same numbered output on the Master. A contact closure on an input of the Master will close the output on the Remote on the same contact.
