Synchronization of real time in PLCs


Thread Starter


We have 8nos. AllenBradley PLC5 processors and 6 nos. Panelview1000e terminals in a ControlNet network. Node#10 is the master processor. The same alarm triggered in different Panelview terminals shows different time stampings due
to the drift in its own real time clock. How to synchronise the real time of all these units with a master PLC processor so that all the PLCs as well as Panelview terminals can have the same time.


Have you defined your date and time tags in the CONTROL TAGS tab under application settings? You then should be able to map the S: registers from the 5 to these tags. Read the help for more info on Y2K issues.
