EPICS TwinCAT-ADS

EPICS module to communicate with Beckhoff TwinCAT controllers over the ADS protocol.

The module provides an asyn port driver, adsAsynPortDriver, that maps EPICS records directly onto PLC symbols. Values can be delivered either through ADS notifications (the PLC pushes changes) or through periodic polling, configurable per record.
