Hello all,
I am on a project using an Allen-Bradley SLC 5/04 communicating to a Windows 2000 pc over RS232/DF1 and KepWare OPC. I am experiencing comm buffer overruns when serving tags, using polling rates of 50 - 10000 ms.
I only have 714 tags (mixed integers and floats, with about 15 string registers), so I don't think the volume of tags is the problem, especially since the overruns occur later if I use a faster polling rate.
Can anyone refresh my memory as to how the SLC 5/04 handles communications? Has anyone seen this problem?
Thanks!
