Welcome to AsyncWago!
This library controls access to I/O on Wago controllers. These are industrial devices with various analog and digital extension modules. They run a basic embedded Linux. Older models don't even have a MMU.
A small control program needs to run on the controller. You can get its source from the Wago Firmware archive.
