Communications Processing Software

Communications control software called communications processing software is installed in
each Communications Module. This software is controlled by the CPU Module after the
power is turned ON. Software need not be installed when the Communications Module is
installed.
The number of channels (CNs) depends on the Communications Module. The configuration,
however, is basically the same as the one shown in the following block diagram.

Communications Process

The communications software required by the Programming Device is called the Communi-
cations Process. It is included in the MP900-Series MPE720 Engineering Tool. This soft-
ware is required for engineering between a Machine Controller and the Programming
Device.
The Communications Process is started automatically if it has not already been started on the
Programming Device. The communications parameters need to be set only once. Refer to
Chapter 4 Communications Process for details.
