"Commands" service
18.7 "Commands" service
The "Commands" service is used to debug the PLC program execution by taking advantage
of the possibility to execute the various parts of the program separately (first cycle, main
module and periodic module). This service also offers the possibility of starting up and
interrupting the execution of the PLC program.
When selecting this service, the horizontal softkey menu offers all the options associated
with this service.

Commands "Run"
This softkey is used to start the execution of the PLC program. The PLC executes the first

by machine parameter. The periodic module is executed according to the frequency defined
in the program.
Commands "Stop"
