ADS proxy

This is a Beckhoff ADS proxy that could resolve multiple connections with same ip address issues.

• ads issue: https://github.com/Beckhoff/ADS/issues/49
• pyads issue: https://github.com/stlehmann/pyads/issues/331

Usage

Download binary from github release page or cargo install ads-proxy, then run ads-proxy.

```shell Usage: ads-proxy [OPTIONS]

Arguments: PLC address, e.g. 172.18.0.10:48898

Options: -d, --debug Debug mode -b, --buffer-size Maximum size of AMS packet [default: 65536] -r, --route Optional ams net id route, e.g. 10.10.10.10.1.1 -u, --username Optional PLC username (to add route) -p, --password Optional PLC password (to add route) --host Optional Proxy hostname (hostname or ip address, detected from PLC connection) -l, --listen-addr Proxy listen address [default: 127.0.0.1:48898] -h, --help Print help -V, --version Print version ```

In pyads, connect to ads-proxy. For example, client 1 and 2 on a host:

• plc ams_net_id=192.168.0.10.1.1
• client 1 ams_net_id=10.10.10.10.1.1
• client 2 ams_net_id=10.10.10.10.1.2

(Might need to add route entry in shell command with -r or in PLC configuration)

shell ads-proxy -d 192.168.0.10:48898

```python import pyads

pyads.openport() pyads.setlocaladdress("10.10.10.10.1.x") # x=1 or 2 pyads.closeport()

plc = pyads.Connection(amsnetid="192.168.0.10.1.1", amsnetport=851, ip_address="127.0.0.1") with plc: ... ```
