Function The internal timer runs for a long as Enable is TRUE.
When the internal timer has reached or exceeded the
configured time value, the status of the output changes
and the timer is restarted. The configured time there-
fore corresponds to half the period duration of the re-
sulting signal. If the Enable input becomes FALSE, the
output also instantly becomes FALSE and the internal
timer is reset.
If the value of Time_ms is less than the cycle time, the
cycle time applies instead.
Initial state All inputs and outputs are FALSE.

9.38.1.3.12 Counter (forwards/backwards)
Description COUNT, incremental counter
Inputs Trigger (BOOL)
Direction (BOOL)
Reset (BOOL)
Lock (BOOL)
Outputs SINT32 (SINT32)
REAL32 (REAL32)
Parameter Reset value (SINT32), -10,000,000… +10,000,000, de-
fault = 0
Function If there is a rising edge at Reset, the output value is set
to the value of the Reset value parameter. A rising
edge at Reset takes priority over all other inputs.
For as long as Lock is TRUE, the pulse signal is not
evaluated and the counter reading is retained. If no in-
put is assigned, the default value FALSE is assumed.
When Direction input = FALSE, the output value is in-
cremented by one with every rising edge at the Trigger
input.
When Direction input = TRUE, the output value is
decremented by one with every rising edge at the Trig-
ger input.
Initial state All inputs and outputs are zero or FALSE.
