Time Synchronization RSlogic 5573

3 posts in this topic

Hi All,

On our plant, we are using one Rockwell  PLC model 5573 with HMI(Allen Bradley 1500P).

I am automation engineer but I did not work on the Rockwell PLC.

Now I am planning to install the GPS clock on our plant. And I want clock will synchronize our Rockwell plc as well.

Could someone advice what is the best option for this model to do the time synchronization.

 

Thanks in Advance,

Warm Regards/Waqar

In order to modify the PLC program, you will need Studio5000 software with RSLinx setup on your development PC.  No PLC programming software, no PLC program changes.

PLC master date/time registers can be manipulated (to synchronize to an external clock) via use of the SSV (Set System Variable) function block.

Attached is a similar example in which the HMI was used as the master time clock, but the PLC modifications will be the same.

I'd suggest you just use the "Logix 5000 Clock Update Tool" to set a schedule, and sync the PLC's to a computer that updates from the GPS.  Much simpler, and no program changes required.
