Appendix A Logic Program Overview
Application Modules
The application modules contain all of the application specific code. This is where a majority of the customizing
is expected to occur and is essentially a programming space where you spend a significant portion of your efforts
to develop proprietary logic specific to your application.
In this example, application code is shown for the Widg-O-matic machine’s assembly application.

SERCOS / CIP MOTION
SIMPLE INCREMENTAL MOVE
The following application example demonstrates how to control a SERCOS / CIP MOTION drive using sequencers &
Motion Instructions.
While the Machine is STARTING / RUNNING, the drive will be operated as follows:
1) Lower Y-Axis - Incremental Distance -2.0 revs
2) DWELL - Time 1 sec
3) Raise Y-Axis - Incremental Distance 2.0 revs
4) Extend X-Axis - Incremental Distance 3.0 revs
5) Lower Y-Axis - Incremental Distance -2.0 revs
5) DWELL - Time 1 sec
6) Raise Y-Axis - Incremental Distance 2.0 revs
7) Retract X-Axis- Incremental Distance -3.0 revs
8) Repeat
The Run Sequence is continuously repeated until the Stop Sequence is initiated by a Machine ABORT or STOP
command.
