Appendix C Sample Applications
The Read Clock from the Powermonitor 3000 unit and Set Clock from
the MicroLogix 1400 controller bits are used to initiate the messages,
and are reset when the message instruction either completes
successfully or an error occurs. In your application code, if the
message rungs are controlled programmatically, be sure that only one
message is enabled at a time.
