brwatch ist a small and portable service tool for B&R automation controls (PLC). It runs on Microsoft Windows and enables you to list, watch and change process variables, start and stop task, search and reboot CPUs, change IP-settings. Additionaly it logs PV values to CSV- Files.
It makes heavy use of PVI ('process visualisation interface') package from B&R.
brwatch comes „as is“, e.g. without support and warranty. You can freely copy it but use it at your own risk.
brwatch needs a previously installed PVI Development Setup to run.
All B&R Controls support INA protocol for online communication, but newer plc support ANSL, too. Since version 4.x PVI supports both INA and ANSL. Brwatch supports both as well but not simultaneously. So starting with V1.1/PVI4.x the newer ANSL protocol could be an alternative by setting 'ANSL=1' in brwatch.ini. In this case, of course, you will not be able to contact old AR 3.x based PLC.
Without a PVI license 1TG0500.02 (+ TG Guard e.g. 0TG1000.02) PVI will run for two hours. After this period brwatch will stop working and PVI-Manager must be stopped and restarted again. Do not blame brwatch for that and contact your local B&R office to buy a valid license.
The project is done in plain old 'C' language (not C++) and makes use of pure Win32-API-calls. Find compiled EXE in releases

A short hint from Koen (Thanks!): "Note: To anyone trying, best to install DevC in a folder without brackets. The default location in Windows 11 is 'C:\Program Files (x86)". However the 'Clean' command fails on the round brackets in the path. If you install under 'C:\DevC' for example, there is no issue. This seems to be a bug with DevC DEL command."
