Requirements
There are many sources that can control an auxiliary relay output when assigned
for “Network” use: an I/O message, and explicit message, DeviceLogix programs,
network fault and idle conditions, and protection fault conditions. An output
point must know how to select which source of data to use to drive its value
attribute. Refer to the I/O Assignments section of Chapter 5 in the 825-P
Modular Protection System User Manual, publication 825-UM004, for
instructions on assignment of functions to the auxiliary output relays.
An output that is not used in a DeviceLogix program follows the rules
described in the State Transition Diagram below.
