Section 3.3 Parameter Status Message Configuration
The PLC interface allows the PLC to display specific status and/or error messages for each configured
parameter, if desired. To do this, the PLC sends a command to the OmniLink OIT that indicates which
parameter is being addressed (there are up to 16 per screen) and the parameter message number to
display (See section 5 for details on the message format). The parameter messages themselves are
configured in this screen.
Figure 3.4 shows an example “Parameter Status Message Configuration” screen.
Features of this screen include:
Message Number Identifies the message for use in the status display protocol. See Section 5 for
details on the use of this number. This is not a configurable item.
