Read data: 12 bytes
Count value: Current counter content
Latch value: If there is a positive edge at the latch input, the count value is stored here.
Ticker value: After mains connection, a timer (s ticker) is started which restarts at 0 after 65535 s.
With every change of the count value, the time value of the timer is stored as 16-bit-s value
together with the count value in the input area.
Write data: 10 bytes
Comparison value: Here you can specify a value which, by comparison with the current counter
content, is able to influence the counter output or trigger a process alarm. The response of the
output or of the process alarm can be parameterised.
Set value: With an edge change 0-1 of COUNTERVAL_SET in the control word, the set value is
accepted in the counter.

Process alarm The activation of a process alarm can be parameterised. A process alarm can be
triggered in the case of the following events:
•Open hardware gate
•Closed hardware gate
• Counter limit overflow
• Counter limit underflow
• Comparison value reached
• Final value reached
• Latch value reached
Diagnosealarm If the diagnostic alarm is enabled in the parameter setting, it occurs if another
process alarm is triggered for the same event during a process alarm processing.
Diagnostic function Diagnostic functions are provided by the modules.
Diagnostic information The diagnostic information describes the diagnostic contents that can be read out of
a module. Diagnostic information is not automatically sent by the module but must
be read out actively via SDO access.
