When a value between 1 and 31768 is specified, the counted value is sent
as soon as the difference between the current and most recently transmitted
counted value reaches or exceeds the configured value.
If no parameter is specified, default value 0 applies; in other words, a
counted value is only sent when a signal edge change from 0 to 1 is
detected at the TriggerInput input , or when (if GeneralTriggerCommand =
TRUE) an organizational. restore command is received.
Note
The difference value must be selected by the user depending on the maximum pulse rate
per second. The value should not be too low otherwise there is a constant transfer of the
message to the TIM. On one hand, this would cause heavy load on the MPI bus/party line
but also stretch the send queue on the CPU.
Note
[Cnt04D_S]
The DifferenceValue processing parameter exists only once in the typical. This parameter
applies to all 4 counted values in common; in other words, it is not possible to set the
parameter for the individual counted values. When using this parameter, each typical should
therefore only acquire counted values that can be processed identically.
