24.5 Trip Unit Programming
AC-PRO-II trip unit has several programmable settings
related to communications. See Section 11.26 for
communications settings.
REPLY DELAY
The REPLY DELAY set point is the minimum delay between
the trip unit’s receipt of a MODBUS packet and its reply.
Adjusting it enables the trip unit to operate properly with
other manufacturers’ MODBUS RS-485 connections.
The factory default of this set point is 5 milliseconds.
The reply delay can be changed using the InfoPro-AC
software application.
