Counter and Timer

Counter and Timer Group Block Diagram

Example: Counter Start Source = OFF

• The counter starts on the counterReset Cmd.

• The counter continues unless a new counterReset Cmd is received, which then restarts the counter at 00.

• When Counter Reset Source= ‘Event’ or ‘CounterEnd’ the counter is reset to 00 but does not restart counting, until the next CounterReset Cmd.

Example: Counter Start Source = CounterEnd (itself)

• Counter starts when Counter Mode is set to Active.

• A Counter Reset CMD will reset the counter to 00 and it then continues counting.

• counterResetSource must be set to CounterEnd. When the counterValue feature reaches the counterDuration value an event is generated and the counter is reset to 00, then continues.

Example: CounterStartSource = EVENT and Signal (Edge Base)
