140
Counter for suction cycles (suction signal)
141
Counter for suction valve switching frequency
143
Counter for suction cycles (suction signal)
– can be deleted
144
Counter for suction valve switching frequency
– can be deleted
The deletable counters can be reset to 0 during operation via IO-Link using the appropriate system
commands.
The non-volatile storage of the counter statuses only occurs every 256 steps. That
means that when the operating voltage is switched off, up to 255 steps of the
counter are lost.
