[brwatch](http://hilch.github.io/brwatch) ist a small and portable service tool for [B&amp;R](https://www.br-automation.com) 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.

[Download](https://github.com/hilch/brwatch/releases)

It makes heavy use of PVI ('process visualisation interface') package from [B&amp;R](https://www.br-automation.com).

## Disclaimer

brwatch comes „as is“, e.g. without support and warranty.
You can freely copy it but use it at your own risk.

## PVI

brwatch needs a previously installed [PVI Development Setup](https://www.br-automation.com/en/downloads/#categories=Software/Automation+NET%2FPVI) to run.

- ### INA/ANSL

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.

- ### PVI License

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.

## Usage

1. [download EXE](https://github.com/hilch/brwatch/releases)
2. [see brief manual](http://hilch.github.io/brwatch/manual)

Find compiled EXE in [releases](https://github.com/hilch/brwatch/releases)

### Build from Source

#### Prerequisites

- MSYS2 with mingw32 compiler
- PVI development headers and libraries (from B&R)
- Resource compiler (windres)
- make utility

#### Setup MSYS2 mingw32

1. Install [MSYS2](https://www.msys2.org/) following the official guide
2. Install required packages:

```bash
pacman -S mingw-w64-i686-toolchain mingw-w64-i686-binutils
pacman -S mingw-w64-i686-winpthreads
```

#### Build Instructions

**Using PowerShell Script:**

```powershell
.\build.ps1                 # Standard build
.\build.ps1 -Clean         # Clean and rebuild
.\build.ps1 -Verbose       # Show all compiler output
```

**Using Makefile:**

```bash
mingw32-make.exe -f Makefile clean all
```

**Using make in MSYS2 shell:**

```bash
cd /c/path/to/brwatch
make -f Makefile clean all
