We released an updated version of our CNCnetPDM IIoT Adapter for machines with Heidenhain controllers that adds new features and enhances compatibility with MS Windows 11 and Server 2022 Operating Systems (up to version 23H2).
On Saturday July 22nd an updated version of our CNCnetPDM device driver for 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, 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.
On January 18th 2023 we released an updated version of our Heidenhain IoT Adapter that enables addition of MTConnect and OPC UA Server functionality to machines with Heidenhain controllers and data output to various SQL Databases.
The updated version uses an enhanced method to establish communication with remote controllers. This fixes issues seen on some newer Heidenhain devices (> TNC 320) where the Heidenhain Data GUI tool was working flawlessly but connectivity between device driver and controller was lost after startup followed by continuous reconnection attempts.
