On Saturday June 20th 2026 we released an updated version of our IIoT device driver that allows data output from Okuma machines with controller version P-100 or higher to OPC UA, MTConnect and/or SQL Databases with major enhancements. We also released a new version of our MTConnect program for analysis of Okuma MTConnect Adapter data with additional features.
MTCCLIENT.DLL 9.0.0.0 (6/20/2026)
Major problems addressed by this version:
Problem: Machine shows up as connected but does not send data
Solution: The driver now enables to define a maximum number of unsuccessful heartbeat (= ping) requests after which it automatically reconnects to the machine.
Problem: Tons of items are acquired that are not needed
Solution: The machine INI file now automatically creates a list of input tag names that allows to enable or disable acquisition of specific tag name/value pairs
Problem: Adapters from different Okuma machines output different tag names for identical items (e.g. ‘path_feedrate’ or ‘p1fact’ for feed rate)
Solution: Input tag names can now simply be translated to standardized, comparable output tag names for different machines
The device driver enables to automatically create a list of valid tag names and types (Events, Samples or Conditions) suitable for all suported Okuma controllers
Provides real time monitoring of Okuma MTConnect Adapters output including Timestamps, Events, Samples and Conditions
Enables analysis, automatic extraction and export of all MTConnect Tags output by Okuma MTConnect Adapters including tag name and type, event, sample or condition
We released an updated version of our CNCnetPDM IIoT Adapter for Okuma machines with several new features and enhancements.
MTCCLIENT.DLL 8.0.0.2 (4/15/2025)
For condition tags the device driver now is able to output 5 elements:
Level (normal, warning, fault or unavailable)
Native code
Native severity
Qualifier and
Text
according to Part 3 of the MTConnect Standard (in previous versions output was limited to ‘Level’). To enable detection of conditions the driver automatically adds entry ‘Condition tags’ to section [MTC TAG NAMES] of each machine specific INI file (e.g. mtcclient_1000.ini). Condition tag entries are created with reasonable default values for Okuma Standard Lathes, 2-Sides Lathes, Machining Centers or Grinders.
Stream data input from devices can now be up to 2047 characters long per packet instead of 1023 in previous versions.
Invalid input from stream data sent by devices is now automatically stripped out.
We released an updated version of our CNCnetPDM IIoT Adapter for Okuma machines that adds new features and enhances compatibility with MS Windows 11 and Server 2022 Operating Systems (up to version 23H2).
