Grouping modules during configuration (PROFINET IO)
Introduction
You can group two digital output modules within a single byte in the process output image to
improve utilization of the available address range of the IO controller. Arrange the electronic
modules systematically, and label these accordingly.
IM 154-4 PN High Feature has a maximum address space of 256 byte for inputs and
256 byte for outputs.

Procedure
The grouping procedure is identical to the procedure for PROFIBUS DP.
