Commands used when working with the Counter Terminal
The output behavior in case of a condition with hysteresis is illustrated
based on the condition "006: counter value of a small start value with
hysteresis.
• If the time measures is not yet greater than or equal to the end value
then the condition is fulfilled and OUT = 1.
• If the time measures is greater than or equal to the end value then the
condition is no longer fulfilled and OUT = 0.
• If the measured time is smaller but is nonetheless still greater than or
equal to the start value, then OUT remains = 0.
• If the measured time is smaller than the start value then OUT = 1.
• OUT is only once more = 0 when the measured value is greater than
or equal to the end value.
The pulse
1 kHz to 10 kHz in 500 Hz steps. For this operating mode, the input wiring
must have a defined setting; this setting is made automatically (see
chapter "System Settings" Command on page 6-12).
The command for the pulse generator comprises the command code and
one factor.
