Crate ads

Work with PLCs using the ADS protocol

Introduction

ADS is the native protocol used by programmable logic controllers (PLCs) and the TwinCAT automation system produced by Beckhoff GmbH.

The specification can be found on their Information System pages.

Example

// Open the connection to a PLC.
let timeouts = ads::Timeouts::new(std::time::Duration::from_secs(1));
let client = ads::Client::new("myplc:48898", timeouts, None)?;

// Get a handle for a symbol and read data from it.
let handle = client.device
