We have Lookout 6.6 processes running on full development servers at separate locations. At Station 1, Lookout is communicating with plcs collecting data. The data here is updating properly. At Station 2, we have expressions looking at data on the Lookout process running at Station 1. At Station 2, our expression might look something like this:
\\192.168.201.10\processname\modbus1.30001 192.168.201.10 is the static IP address of the Lookout computer at Station 1.
If for some reason the computer at Station 2 is restarted, the value of the expression shown above will often times be incorrect when Lookout comes back up. It will stay incorrect until the actual value of the expression changes at Station 1, or we modify the expression at Station 2 and type it in exactly as it was. Somehow, this forces the expression to update and the value will be corrected. This is causing significant problems because we cannot rely on the values shown at Station 2 to be correct on signals that aren't continuously changing.
I have installed the latest Logos engine (via a Lookout 6.7.2 install) to try and address this issue, and it does appear to be better, but the problem is still occurring. The problem is not an inability to communicate between Station 1 and Station 2, because modifying the expression at Station 2 to be exactly as it was causes the numbers to properly update.
Any suggestions to address this problem will be appreciated very much.
