Internal process data mapping with data format “Standard”. Depending on the fieldbus specification and the data
format of the communicating fieldbus components the bytes and/or words can be reversed during data transfer.
5.6.6 Time Stamp Function
With time stamp function (ETS = edge time stamp) enabled, at every corresponding edge
the time value of the timer is stored in the process image as an ETS entry together with the
status of the inputs and a running number.
The module does not use any bytes in the output range. It uses 60 Bytes in the input range
for 15 ETS entries each with 4 bytes.
