This device driver requires at least Version 18.104.22.168 of CNCnetPDM and also works with a free license. However, in this mode the driver only outputs the first two items you defined in section [MTC TAG NAMES]. With a valid license you are able to output up to 70 items from the controller, see licensing for details. TOP
Edit CNCnetPDM.ini (or CNCnetPDM+Instance.ini) and modify it as follows, leave all other values at their default:
AcquisitionMethod = 2 This driver uses unsolicited (event driven) communication.
PollInterval = 10 Define the interval (number of seconds) for checking if the device is connected.
ReconnectAfter = 3 Define after how many successful connection checks CNCnetPDM should try to reconnect to the controllers MTConnect Adapter if the device changed its state from disconnected to connected. As the machine needs some time to start up the combination of PollInterval and ReconnectAfter should be long enough e.g. 10 x 3 = 30 sec. For older machines increase this value.
CollectStates = 0
CollectCounters = 0
For initial testing its recommended to set CollectStates and CollectCounters to 0. If you set them to 1 please make sure that you have matching tag names for OEE device states and part counter set up in the respective machine INI file. TOP
If you identify your controller by IP address change it from 127.0.0.1 to its correct address e.g. 192.168.1.100.
If you identify your controller by DNS-Hostname change it from localhost to its correct value e.g. MAZAK01.
Change the name of the device driver from device.dll to mtcclient.dll
This device driver enables to dynamically modify, enable or disable tags that should be acquired from the controller. It also allows to define the frequency and content of ping commands that have to be sent to the Adapter. Definition of a tag name for availability enables the driver to determine if the controller connected to its Adapter is up or down. By setting a tag name and possible values for OEE device states you can output numeric values for these states. Setup of a part counter tag name allows incremental or cumulative part counting in CNCnetPDM.
Section [GENERAL] contains information about the ping interval in seconds (default 10) and the command (default ‘* PING’) to be sent to the Adapter. TOP
In section [MTC TAG NAMES] you can limit tags to be acquired from the device. Valid tags are identified by their name and have to be delimited with pipe ‘|’ characters. By default 34 names are included, maximum = 70.
In section [AVAILABILITY] you can define a tag name that should be used to determine if the controller connected to its Adapter is up or down (default ‘avail’). MTC Adapters usually provide this tag. For Adapters that do not output this tag you can use any tag name that changes to ‘UNAVAILABLE’ if the controller goes down f.i. ‘execution’.
Section [OEE DEVICE STATES] contains a tag name (default ‘execution’) and its possible values for states Producing (2) (default ‘active’), Manual (3) (default ‘stopped’) and Interrupted (4) (default ‘interrupted’). CNCnetPDM automatically reports (0) for devices that are not reachable at all and (1) for reachable devices where the Adapter does not respond. TOP
In section [PART COUNTER] you can define which tag name (default ‘part_count’) outputs numeric part counts. This enables you to use CNCnetPDM’s cumulative or incremental part counting features that allow detection of reset operations at the controller.
Note: To change the content of this INI file while CNCnetPDM is running open it with a text editor such as notepad, make the desired changes and save the file. To apply the changes immediately you can click on the machine in CNCnetControl on the left side followed by clicking buttons ‘Close’ and ‘Open’ above the section ‘Devices’. TOP
The device driver writes a log file entry for any communication issue to the log file of the device. The file can be found in subdirectory \log of your CNCnetPDM program folder. The file format for the log file is log_ + device number + _ + date.txt. Please check this file first if you observe an issue.
If the machine shows a red icon, state disconnected the machine is not reachable at all. This has nothing to do with the device driver, the controller is switched off, it’s a network issue, DNS Hostname or IP Address is wrong. With CollectStates = 1 set in CNCnetPDM.ini you get output E 0 in regular intervals in this case.
If the machine shows a green icon, state connected but you do not see any output even there is activity at the controller the machine is reachable but the MTConnect device driver is not able to connect to the Adapter at the controller. In this case, check your controller setup and the parameters used in section [RS232] of CNCnetPDM.ini. Please use the tool MTConnect Agent Tester to check if you are able to connect to the Adapter and get data. With CollectStates = 1 set in CNCnetPDM.ini you get output E 1 in regular intervals in this case.
