Description

Use the DTL_RMW_W function to perform a read/modify/write function

on a data item. The function reads a data value, modifies the data with the

AND mask and then with the OR mask, and writes the data back to the

programmable controller.

This synchronous function cannot be used on multiple-element data

definition. The element must be a word value.
