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.
