2.4 Timers and counters
2.4.1 Timers
48 timers are available in the PLC. These 48 timers are controlled by special markers with the
abbreviation symbol T. The time period for the timer is defined in the machine parameter MP4110.X.
The time unit corresponds to the PLC cycle time.
The timers are started by setting the markers T0 to T47 which also sets the timers to the value from
MP4110.X. This activation may only be performed for a single PLC run, as otherwise the timers will
be restarted by every succeeding run.
The markers T48 to T95 (timer running) will remain set for the period defined in the machine
parameters.
