- Important points to note regarding setting performing Bit Write operations
- With a Bit Write operation, the word data is first read from the PLC, and a logic operation
(AND or OR) is performed on the relevant bit before writing it to the PLC to ensure
that the values of other bits in the same channel are preserved. However, be certain that
the PLC does not modify the data in the channel during the time that the MICRO/I is
writing the data.
