For QJ71PB92D and QJ71PB92V master modules consistency can only be ensured, if

autorefresh with consistency is used for data transfer between CPU and master.

The A(1S)J71PB92D master maintains consistency in both A- and QnA-series systems.

For A(1S)J71PB92D and QJ71PB92D in operating mode 0 no POU can be generated.

Note:

The ASCII file must be imported in GX IEC Developer. If a user library is referenced, it will

automatically be imported as well.

Because the ASCII file contains the absolute path of the user library, the user library must

not be moved to a different directory.

The 'I/O Mapping POU' can be created in a full or a reduced version, i.e. with or without code for

slave modules.

For A-CPUs (i.e. a transfer setup with an A-CPU is currently selected) only the reduced POU is

available.

If the user selects to include the code for slave modules, the POU respectively the user library will

also contain DUTs and global variables representing the slave modules. Separate networks will

copy the I/O data of the slave modules between the global variables of the modules and the

transfer buffer. The additional global variables and devices, which the user has assigned to

individual I/O areas of modules, are also only included in the full version of the I/O mapping POU.

The benefits of the reduced POU are lower memory consumption and less programming

instructions. The disadvantages are the higher programming effort for the user and the required

knowledge on the I/O structure of the slaves.
