ON pulse time, OFF pulse time
ON pulse time and OFF pause time must be greater than zero in order to get a pulse action.
Pulse action occurs only when the process contact is active (delay or advance time is consid-
ered) and always starts with an ON pulse.
Example for using a process contact
A smoke generator needs a certain advance time in order to provide the smoke which is re-
quired for the "smoking" process step. For this purpose, in the correspondent process step, the
process contact for starting the smoke generator is defined as "switch-on advanced" and the
advance time (control function time) is specified.
