• The communication path goes from the local
1756-DHRIO module across the DH+ network to
another 1756-DHRIO module on the same DH+
network. (1)
• The remote 1756-DHRIO module is node 12 octal or
10 decimal. (2)
• This 1756-DHRIO module at node 12 is located on the
same backplane as a 1756-DH485 module in slot 14. (3)
• Channel A (4) of the 1756-DH485 module is on a
DH-485 network (5) with an SLC 5/03 controller as
node 1. (6)
