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 the words can be
reversed during the data transfer. For byte/word order for each fieldbus coupler refer to Section 3.10.

Modulation Output Module
EP-5422
The digital pulse width modulation module EP-5422 is used for the control of small motors
with current requirements of up to 0.5 A. The period duration for each channel can be
parameterized from 25μs to approx. 175ms (input values from 1,202 to 8,388,607 based
on a factor 0.02083μs).
Via an output double word in the process data the pulse duration is defined from 0μs to
approx. 175ms for each channel (input values from 0 to 8,388,607 based on a factor
0.02083μs). If the pulse duration is equal or exceeds the duration of the period, the output
is set permanently.
