13.5 COUN (up/down counter)
‘COUN’ is an up/down counter and counts the events at input up or down, which are available at the up or down input
for at least the duration of the time group in which the function runs.

Pulse diagram of the up/down counter:
Example:
max. limit = 9; min. limit = 0; Preset = 7.
An unwired clock input is set to value 1 internally. If both clock inputs go from 0 to 1 signal simultaneously, counting is
omitted. If one of clock inputs (up or down) are set from 0 to 1 signal, without the other one being already set to 1,
counting is omitted.
If parameters for the min. or max. limit are changed during operation, the counter can be out of this new range. In order
to prevent faulty functions, the counter must be set to a new, defined output status with ‘reset’ or ‘preset’. The function
has a ‘memory’. This means: after power-on, it continues operating with counter state and internal states at power-off,
provided that the RAM data are still unchanged.
