Communications 7-5
To enable motor control from a connected human interface module or
communication module, you must take the following programming
steps:
1. Disconnect the HIM and allow to power down.
2. Reconnect the HIM. On Initializing screen, the bottom right cor-
ner of LCD shows Port X. Note this port number.
3. Go to Logic Mask, found as follows:
Main Menu: Parameter/Communications/Comm Mask/Logic
Mask
4. Set b0X equal to 1 (where X is the port number noted in step 2).
Important: The Logic Mask must be set to 0 prior to disconnecting
a human interface module from the SMC-FLEX
controller. If not, the unit will fault on a “Coms Loss”.
