Download CNCnetPDM (Version 5.0.0.0)

Version 5.0.0.0 (3/20/2018)

We released an updated version of CNCnetPDM with major enhancements and less restrictions. The previously used 1 device and 1hr time restrictions for the ‘free license’ were removed, there are no more limitations on time or number of devices.

With a ‘free license’ device drivers now output a smaller set of items such as ‘device state’ plus one additional fully configurable item. For simple tasks like monitoring device states this is perfect.

We also added new annual subscription models for CNCnetPDM starting at more than affordable USD 349 (EUR 285). Note that all licenses are valid for all device drivers and diagnosis programs! TOP

Version 4.9.0.3 (2/12/2018)

An updated version of CNCnet PDM with proper support for MySQL and MariaDB databases (Version >= 5.5) is available for download. As Data Types in MySQL and MariaDB differ from Oracle we created an own page with database and table setup instructions. We also added setup instructions for CNCnetPDM database connectivity to these products.

ERPINTERFACE.DLL

Version 4.9.0.3 of erpinterface.dll now supports all product-specific 'select', 'insert' and 'update' commands for MySQL and MariaDB databases. Mixing of machine data with work-orders, items and parts from solutions for operational data acquisition as well as detection of an active shift for specific devices is also included.

Appart from using the correct UDL file in section [Connect] of CNCnetPDM.ini 'DB_TYPE = 3' has to be used for MySQL and MariaDB databases.

Note: For users of CNCnetPDM 4.9.0.2 it is sufficient to just exchange erpinterface.dll with the most recent version. TOP

Version 4.9.0.2 (1/15/2018)

We released an updated version of CNCnetPDM with some major changes and enhancements.

CNCnetPDM.exe

CNCnetPDM now supports sampling rates down to 1 second. To simplify configuration we removed all legacy entries from CNCnetPDM.ini.

erpinterface.dll

For just monitoring all actual data from devices this module now supports updating the new table MTH_ONLINE_DATA that just keeps the most recent data of each device. Setup instructions for MS SQL Server. Instructions for Oracle databases. As we’d like to enable you to decide what to write we introduced 2 new entries in section [Connect] of CNCnetPDM.ini, WriteRawData (default = 1) and WriteOnlineData (default = 0). To decide what to use you can add these two entries manually to existing setups, for a new installation these items are added automatically.

cncinterface.dll

This module now also supports ultra-short sampling rates. As initialization of a controller connection may take some (older Mitsubishis: up to 60 seconds) we had to add a new entry to section [GENERAL] of CNCnetPDM.ini that controls the frequency for CNCnetPDM to try to re-establish communication with the controller if communication is lost. The name of the entry is called ReconnectAfter = 2 (default). If you set PollInterval = 30 it’s ok to use 2 as there’s 60 seconds to establish communication. If you use ultra-short polling rates please use a number for ReconnectAfter that is high enough for your controller (e.g. 10). This driver now also provides improved functions to cleanup handles and free memory if connection gets lost (required for Heidenhain device driver!). For an existing setup you can add this entry manually. TOP

Version 4.9.0.0 (8/20/2017)

This release contains useful new features and major improvements.

CNCnetPDM.exe

As this version doesn’t contain a preconfigured INI file you don’t have to worry about overwriting your existing configurations. If there is no CNCnetPDM.ini file it is automatically generated with reasonable default values.

Newly created INI files contain descriptions for all settings.

The maximum size (in MB) of offline files can now be adjusted by entry SIZE = in section [Offline] of the INI file. When this size is reached CNCnetPDM automatically creates an additional file.

You can now switch the output of each item acquired by device drivers to section 1,2 or 3. This enables you to build groups of items and place long values (e.g. axis data) into an own group.

erpinterface.dll

On first startup CNCnetPDM adds entry ‘StartOffline = 1’ to section [Connect] of the INI file. With this entry set to 1 CNCnetPDM doesn’t try to connect to a database on startup, all data goes to a text file in the offline directory. In this mode you can manually connect to the database with CNCnetControl. If you set this entry to 0 CNCnetPDM automatically tries to open the database connection on startup.

cncinterface.dll

Device driver DLLs are now automatically created with the machine number added to the DLL, e.g. Fanuc_1000.dll for machine 1000 as sequential numbering caused problems when machines were commented out.

This module now also checks for existent and valid device drivers and writes the results to the log file of the device.

Error reporting from device drivers and its underlying components is now fully supported. For example, if your Fanuc FOCAS call returns a manufacturer specific error like EW_PROTOCOL it is translated into ‘Protocol error’ and written to the log file of the device. This allows you to quickly find out errors or switch off unsupported functions via the device driver INI file. TOP

Version 4.8.0.1 (6/8/2017)

This service release fixes some issues experienced by users when CNCnetPDM is used without a database or in case the database connection gets lost. Security and stability improvements were also applied.

CNCnetPDM.exe

Incomplete, garbled messages that sometimes (esp. under Windows XP) led to crashes are automatically detected and filtered out.

erpinterface.dll

Database connectivity components were redesigned. Message fragments are now automatically filtered out. Occasional crashes when closing the programs are resolved.

cncinterface.dll

Message fragments are now automatically filtered out.

Note: To update an existent setup of CNCnetPDM you just have to stop the service, replace the files in the setup directory of CNCnetPDM with the 3 files listed above from the zip archive and restart the service. TOP

Version 4.8.0.0 (4/23/2017)

See also: Details about the changes in version 4.8.0.0

CNCnetPDM.ini

All default tag names are shorter now e.g. STATUS instead of STATUS.CNCNETPDM. In section [ERP] new entry Changeddataonly = 0 is automatically added when CNCnetPDM is started. If this entry is set to 0 ALL item values are output on every reading cycle. If set to 1 all items values are output on the first reading cycle, subsequent readings only output item values that have changed since last reading.

erpinterface.dll

The database table for raw tag data has changed from MTH_TAG_READINGS_RAW to MTH_RAW_DATA (Both MS SQL Server and Oracle). Output records are now automatically generated by processing incoming telegrams that contain multiple tag names (TAG_CODE) and tag values (TAG_DATA).

device.dll

This device driver now outputs data with multiple tag names and random values in single telegrams. If CollectOrders is set to 1 in CNCnetPDM.ini (Section [GENERAL]) more details about controller mode, NC program, feed rate, spindle speed aso. is output. With CollectFeeder = 1 axis data is also output. Tag output can now be dynamically activated/deactivated on a per machine basis by using an own ini file for every machine. Tag names can be freely defined per machine. The functionality is similar to the most recent driver for real machines with Fanuc controllers, fanucext.dll.

cncinterface.dll

If entry Simulation in section [GENERAL] is set to 1 in CNCnetPDM.ini output of random data is no more delimited with pipe '|' symbols as this would lead to generation of wrong tag names by erpinterface.dll. TOP

Version 4.7.1.0 (2/18/2017)

CNCnetPDM.exe

General:
Various performance improvements were applied.

Message buffers:
The maximum number of messages allowed to wait for processing can now be adjusted via the entry VERBUCHUNG in section [Hochwasser] of CNCnetPDM.ini (e.g. VERBUCHUNG = 100). If this limit is reached messages are written to an offline file. On lower deviation of this value CNCnetPDM automatically switches back to online processing. This is very useful if a database occasionally slows down due to high traffic.

Offline files
The maximum size of offline files can now be adjusted by the entry SIZE in section [Offline] of CNCnetPDM.ini. If not present it is automatically created with value 1 (= 1 MB). If this limit is reached CNCnetPDM creates a new offline file.

cncinterface.dll

Device state:
Detection of state switched on / off was modified to work correctly for devices that do not have a DNS Host record if UseDNS is set to 0 in CNCnetPDM.ini.

Message length:
The maximum length of each message was increased from 89 to 255 characters.

Machine dll files:
Incorrect duplication of individual device driver dll files when starting and stopping CNCnetPDM as a thread was fixed.

erpinterface.dll

Reconnect behavior was improved if high values (> 100) are set for entry ReconnectAfter in section [Connect] of CNCnetPDM.ini.

CNCnetControl.exe

A buffering problem was fixed that led to occasional crashes on startup when a high number of machines and messages per device are configured. TOP
