The communication object “level increment/decrement, X” is used to increase/decrease the level of the switch. It will
increase one level when sending “1” and decrease a level when sending “0”. The detail process will be describe in the
switching sequence parameter chapter.
Form 5 Communication object “Switching sequence”
6.6. Communication object “Counter”
The communication object “Counter” will be shown in Fig.6.6. Including standard counter and
differential counter communication object, both these communication objects are initiated counter by one
operation and the counter range are the same, but the counting are independent of each other.

This communication object is used to transmit the current counting value of the standard counter, and it can modify the
counting value simultaneously. Different data type makes the different counting range, it is defines by parameter “Date

It is visible if enable the parameter “Enable differential counter”. This communication object is used to transmit the
current counting value of the differential counter, and it can modify the counting value simultaneously. Different data type
makes the different counting range, it is defines by parameter “Date width of counter”.

This communication object is used to ask for the current counting value of the standard counter and the differential
counter. The communication object “CH X Counter value” and “CH X Differential Counter” will transmit the current counting
value if receive a logic value “1”, it will no reaction if receive a logic value “0” telegram.
