Support Software I/O Allocation Functions

The Support Software provides a display of the I/O allocation for the Slave Terminal configuration. This
display shows the bit offset and size of the data allocated for a specific configuration as well as other
important information. Use this display to understand the mapping of I/O data within the Slave Terminal
for accurate network variable assignment in the PLC.
In the Multiview Explorer, right-click the EtherNet/IP Coupler and select Display I/O Allocation from
the menu.
