The constant in the expected receive
message that is set in the protocol
macro is different from the constant in
the message that was received.
Correct the expected receive mes-
sage that is set in the protocol macro
or the message that is sent by the
remote node so that the constant in
the message is the same.
Set the system so that the expected
receive messages that are set in the
protocol macros agree with the mes-
sages that are sent by the remote
nodes.

Prevention
The protocol macro data is not set
correctly.
The baud rate, frame format, or other
system setting does not agree with
the remote node.
Check if the protocol data and system
settings are set correctly with a trans-
mission line trace from the CX-Proto-
col.
Correctly set the protocol macro data.
Make sure that the baud rate, frame
format, and other system settings are
the same as for the remote nodes.
