Controlling the counting process

SW gate = closed SW gate = open

HW gate = closed

Internal gate

closed; counting

process stopped

Internal gate closed; counting process stopped

HW gate = open

Internal gate

closed; counting

process stopped

The internal gate is open. The pulses are detected by the

counter.

The behavior when the high counting limit is violated de‐

pends on the setting of the "Reaction to violation of the high

counting limit (Page 41)" parameter).

5.3.2

Counter in operation (startup and stop)

The following behavior applies to the configured CFU with assigned parameters.

Start

The counter starts at 0 after the following events:
● Startup of the CFU
● Count value exceeds the high counting limit
● Restart of the CPU (STOP -> RUN)
● CPU/CFU connection is restored

Stop

The count value is frozen after the following events:
● Internal gate closed
● CPU in STOP
● CPU/CFU connection is terminated (for example, PN cable disconnected)
