On Saturday July 22nd 2023 an updated version of our CNCnetPDM device driver for monitoring machines with Heidenhain controls was released that resolves problems and introduces new features.

We fixed a major issue that prevented the device driver from connecting to NCK based controllers TNC 320, 620, 640 and TNC7 with newer NC Software Versions e.g. 340595 on TNC 640. Log files showed repeated 'Device protocol initialization succeeded' followed by 'communication lost' entries.
Detection of successfully established connections in both directions was enhanced.
The driver now allows to read and write parameter values by symbolic names (f.i. CfgFeedLimits.maxFeed.PA1) from/to NCK based TNC 320, 620, 640 and TNC7 controllers.
Acquisition of workpiece counter values was adjusted to support changed locations on NCK based devices with newest NC software versions.
