Swap Function - Mitsubishi Electric CC-Link IE Field NZ2GF12A-60IOLH8 User Manual

Swap function

This function swaps the upper and lower bytes of data sent and received between the IO-Link module and the IO-Link device
connected to each channel.
With this function, there is no need to program an operation to swap the upper and lower bytes when using an IO-Link device
that handles the upper and lower bytes in reverse.

Description
Enable or disable data swap for each channel using the parameter setting window of the engineering tool or via a program.
Enable this function by enabling the seventh bit of the corresponding channel of the process data size (access code: 20H) of
the data to be read or written in transient communication. ( Page 86 Process data size)
To apply the data swap setting changed in processing other than the initial processing, turn on Operation condition setting
request flag (RWw0.b9).
For details on setting parameters via a program, refer to the following.
