Overview of RS-422 Communication Unit
Section 4-1
The following types of CompoWay/F messages communications are sup-
ported.
Note The following table lists the CompoWay/F commands that can be
sent to the Communication Unit.
Note When using a PLC as the master to send CompoWay/F message communi-
cations, CompoWay/F commands are executed from the Serial Communica-
tions Board or Unit using the following standard system protocol macros.
