Good day,
I’m having serious issues with one of my gateway installations, here is a brief breakdown of what I’ve seen so far:
-
“Error Browsing OPC” Timeout exceptions whenever I open the designer. This makes it impossible to create new tags or modify the existing tags, since the OPC server becomes inaccessible.
-
“Operation exceeded the allowed amount of time to finish” whenever I modify any device settings, or OPC server settings.
Any suggestions are appreciated… Thank you.
A few pertinent details about the gateway:
Version: 7.8.4
Devices: 22 modbus tcp, 4 siemens s7
Tags: 510 across all devices
Memory Usage: ~ 400mb / 3gb
CPU usage: ~ 30%
OPC max per operation: 10 (any higher leads to all tags having “uncertain” quality)
Scan Class: @5000ms
Custom Modules: 1 module that subscribes to all tags, and pushes value changes to a RabbitMQ exchange. 1 module that retrieves several file streams from an FTP server every 5 minutes, and creates/updates driver tags with the file contents.
