### slave-rnd

Slave emulator that generates random answers to read requests
and positively acknowledges on write commands. Useful for fast check of Modbus
masters like SCADA systems, custom client implementations, etc.

![](https://raw.githubusercontent.com/alexs-sh/modbus-tools/master/docs/pics/slave-rnd.gif)

The easiest way is to build and run via Cargo. By default, Modbus TCP uses 502
port that, in most cases, requires root privileges. Therefore all examples are
presented on port 1502.

```
cargo run --bin slave-rnd tcp:0.0.0.0:1502
..
[2022-07-08T14:49:25Z INFO  slave_rnd] start server 0.0.0.0:1502
[2022-07-08T14:49:25Z INFO  slave_rnd] start message processor
[2022-07-08T14:49:25Z INFO  slave_rnd] press Ctrl+C to exit
[2022-07-08T14:49:27Z INFO  transport::tcp::server] 127.0.0.1:44544 connected
[2022-07-08T14:49:30Z INFO  transport::tcp::server] 127.0.0.1:44548 connected
```

Run with verbose output.

```

```

Run in serial mode.

```
cargo run --bin slave-rnd serial:/dev/ttyUSB0:38400-8-N-1
```

### slave-exchange

A slave emulator allows connecting N masters. Some masters can write into
registers, and others can read. Typical usage is temporary storage for
connecting different components of a system.

![](https://raw.githubusercontent.com/alexs-sh/modbus-tools/master/docs/pics/slave-exchange.gif)

Running:

```
cargo run --bin slave-exchange tcp:0.0.0.0:1502 udp:0.0.0.0:1502 serial:/dev/ttyUSB0:9600-8-N-1
..
[2022-12-07T19:43:18Z INFO  transport::builder] start tcp server 0.0.0.0:1502
