The Modbus address is used to identify the MCTB on the serial link. When a multi-drop connection is used,
each controller on the link must have a different address so that each one can be identified separately. If two
or more MCTB controllers have duplicate addresses, communications with those controllers will fail because
they will each try to respond to the same message. For single MCTB connections, the address only needs to
match that of the commands being sent from the host device.
IMPORTANT: See Appendix section A.1 Modbus Communications for details on the available data and
functions supported.
