15. Numbers Used to Identify Parameters in
Multi-Comm Messages and Athena Plus
Protocol
Skip this section if you are configuring a 16C, 18C, or 25C
controller using its front panel (or using a MODBUS host). The
information in this section does not apply to your situation. The
table below is provided for users of Multi-Comm software and
other custom applications that take advantage of the Athena Plus
communication protocol.
The table below lists all the configuration parameters and the Athena Plus protocol
identification code for each. It also contains setpoint and status values that can be read
by applications that are compatible with the Athena Plus protocol, such as the Athena
Multi-Comm application.
The “used by” column shows which of the Series C controllers can use the parameter.
“All” means 1ZC, 16C, 18C, and 25C. However, even if a parameter can be used by a
controller model, the parameter may not apply to every control strategy. See the
descriptions of the parameters in Sections 5 through 14 for information about
applicability.
