RSLogix Clock Update Tool Problem

[pr_wainwright]

Hi,
I have installed Rockwells Clock Update Tool on a SCADA PC to hopefully keep the associated PLC's clock in sync. The problem is that the Clock Update Tool reports that the times are in sync when my device is selected but the log indicates a write fail. The clock in the PLC seems to sync when I use Synchronize Device menu command but the hour is one less than the SCADA PC. The device has a red 'x' next to it in the Clock Update Tools GUI.

Any help appreciated.
Thanks
Paul.

Found the 1 hour difference problem. I have been using DateTime instead of LocalDateTime in GSV WallClockTime function.

Paul, please add some infos about your architecture:

PC operating system
PLC type, model, firmware
Clock Update Tool version

(About the time difference, take a look to the GSV WallClockTime Object's attribute you're using... DateTime and LocalDateTime attributes could be the issue...) wow... just posted this during the time you wrote the same things...

fuzzy_logic,
SCADA OS is Windows 7, Clock Update Tool V2.4 PLC CompactLogix L32E (Firmware V17.2)

If I try the Clock Update Tool on my development laptop PC (Windows XP) the Clock Update Tool works correctly. Both SCADA & development PC's are connected via Ethernet. RSLinx Classic on the SCADA PC seem to find the PLC no problem though?

Regards
Paul.

Yeah, as suspected, I know of an issue like the one you got, using Windows 7... it is officially defined as "Unknown compatibility issue", and as far as I know, is still unresolved.

fuzzy_logic,
Thanks for the reply. The tool seems to work fine when I change the PLC clock time it syncs correctly when scheduled but I get the red 'x' next to the device?

Regards
Paul.
