CNCNETPDM VERSION 8 RELEASE | NEWS

TOP

On Sunday November 19th 2023 we released CNCnetPDM 8.0 a major version that comes with new and updated features, performance improvements and bug fixes.

CNCnetControl Version 8

FIG 1: CNCnetControl Version 8.0

NEW FEATURES

  • All device drivers now additionally output the machine’s device name (as defined in CNCnetPDM.ini) to the CNCnetPDM OPC UA Server, MTConnect and SQL Database modules.
  • Driver device.dll now supports simulation of unsolicited messaging down to intervals of 100ms, ideal for testing of scenarios where multiple devices output data in high frequency.

UPDATED FEATURES

  • Device drivers are now automatically set to work in unsolicited mode if this acquisition mode is selected in CNCnetPDM.ini.
  • All components of the OPC UA Server module were updated for enhanced speed and lowered memory consumption.
  • The MTConnect Adapter module now correctly sends all TAG|VALUE pairs including device name on connect or reconnect of MTConnect Agents.
  • Compatibility with MS Operating Systems Windows 11 and Server 2022 up to version 23H2 was highly enhanced.

PERFORMANCE IMPROVEMENTS

  • Checking of reachability of a device over the network on every reading cycle is now omitted if the devices Application Program interface (API) responds, in both solicited and unsolicited mode.
  • Timeout for checking reachability of a device over the network is now lowered to 100 milliseconds, was 1 second in previous versions.
  • Duplicated events (e.g. ‘Device is not reachable’) are not written to log files.

BUG FIXES

  • CNCnetPDM now prevents from duplicate starting of identical program or service instances.
  • CNCnetPDM and CNCnetControl now correctly identify the connection state of a device as disconnected (unavailable) if it can be reached over the network (‘E 1’) but their API does not respond.
  • Important note: Licenses for CNCnetPDM 7.x are still valid for this version. However, all device drivers have to be updated to version 8.x otherwise they fall back to restricted mode.
