NO-LINK message appearing typically on a Carel PGD1 displays when connected to a Carel PCO's

This video will guide you through the procedure to clear the NO-LINK message appearing typically on a Carel PGD1 displays when connected to a Carel PCO3, PCO2, PCO1 or even a PCOXS controller. This message is not referring to an alarm condition of the system but simply to a miss-communication between the PLC controller and the PGD Display.
