R413D08 8 Channel Module

This RUST project can read and write a R413D08 module from the command line. It should also work with the R421A08 relay card because it has the same Modbus commands.

Hardware

The following hardware is required for this project:

• One or more R413D08 8 channel modules.
• One or more relay modules 1-8 channels.
• One USB-RS485 converter.

Data sheet R413D08

• Operating Voltage: DC 5 Volt (5V version) or DC 6-24 Volt (12V version)
• Operating Current: 10-15 Milli-Ampere

Compilation

1. Install Rust e.g. using these instructions.
2. Ensure that you have a C compiler and linker.
3. Clone git clone https://github.com/acpiccolo/R413D08-Controller.git
4. Run cargo install --path . to install the binary. Alternatively, check out the repository and run cargo build --release. This will compile the binary to target/release/ch8ctl.

Getting started

To see all available commands:

ch8ctl --help

For TCP Modbus connected temperature collectors:

ch8ctl tcp 192.168.0.222:502 read
