Integrating The HiProm GPS Module (1756HP-GPS) into a ControlLogix Sequence of Events Module System B-5
In this example, the following are required:
• The CST in each ControlLogix system must be synchronized
across chassis.
• Each ControlLogix system must contain a 1756HP-GPS module.
• Once the controllers in each system receive CST format
timestamps, they must send the timestamps to the 1756HP-GPS
modules in their respective chassis for conversion to UCT in wall
clock format.
