Timer preset value not acting like expected

Hello, Ive created a tag to read/write a timer preset to a slc505, and the value comes back as zero, when I have a known preset of 30 seconds in the timer. Im using t4:15.pre for the source. Ive also tried this on a SLC503 with a net-ENI interface, and get what appears to be the .acc value instead of the .pre value.
Ive tried every tag type available to no avail.
Thanks for any help or suggestions.

What version are you using? This may have been an issue that was fixed recently.

7.7.0

It was a version issue, upgraded to 7.7.1 and problem solved.
thanks, mike
