For manufacturing machines from Citizen or Mazak equipped with Mitsubishi controllers this diagnostic tool enables you to test reading and writing operations by using all available commands for these devices. It enables to quickly setup customized Mitsubishi Citizen device driver INI files for CNCnetPDM. The program can be executed on a PC with MS Windows OS (>= XP SP3) connected to your controller via Ethernet. Please use MitsubishiCommands for machines from manufacturers other than Citizen or Mazak.

As the program identifies and accesses controllers by using machine numbers the first thing you have to do is to edit the configuration file melcfg.ini
Machine numbers are defined in sections, one for each device. The machine number is the numeric part after Machine, e.g. [Machine01] = 1. Note: The second part of this numeric value uses hexadecimal notation from 1 to F, e.g. 01 = 1 and 0F = 15, remember your math lessons
If you’re testing with one machine it is recommended to leave section [Machine01] as it is. Only in case it doesn’t work you can change the value for Controller from M8NX to NCXJ, NCXK, M6B, NX or M7NX
It is necessary to adjust section [HOSTS] according to your setup e.g. TCP1=192.168.100.1,683 means that the IP Address of your controller is 192.168.100.1. 683 after the comma is the port to be used to access the controller, do not change that
For additional machines you have to copy and paste the whole section [Machine01], then change its name e.g. [Machine02] and Device= to a different device in section [HOSTS] e.g. Device=TCP2. In section [HOSTS] you have to add a new device e.g. TCP2=192.168.100.2,683
In field ‘Mitsubishi Machine Number’ (1) enter the machine number as defined in melcfg.ini
Initially the program starts with Mitsubishi Command (2) SECT_RUN_STATUS which returns the running status of the machine
Clicking on button ‘Execute’ (3) shows the result of the operation, here 2, in the right area:

Data Type (5): Allows you to adjust the data type for the command. Please select a data type according to the expected result e.g. for integers T_LONG or for floating point numbers like common variables or axis position T_DOUBLE or T_FLOATBIN. If you expect text output use T_STR.
Parameter Value (X) (6): For commands that require a parameter value like a common variable number SECT_COMMON_VAL1(x) you can enter it’s number here. Input this parameter for commands that end with (x).
Axis number (7): For axis related commands e.g. Axis Name SECT_AXIS_NAME a specific axis number has to be entered here.
Part System (8): If your machine has more than one part system you can adjust this value.
WRITE DATA
CitizenCommands also allows you to change data at the controller by using writable commands e.g. common variables SECT_COMMON_VAL1(x). To change the value of common variable 501, proceed as follows:
In field Mitsubishi Command (9) type in SECT_COMMON_VAL1(x). You can also copy the command name and paste it into this field by clicking on the button with 3 dots right of the input field
As Data Type (10) select T_DOUBLE
In field Parameter Value (11) enter 501
Activate checkbox ‘Write to Controller’ (12) and enter the new value for variable 501 in the input field below
Clicking on button ‘Execute’ (13) changes the variable value and shows the result in the right area
You can verify the new value for common variable 501 at the controller (14)

LICENSING
If you have installed CNCnetPDM on your PC with a license other than a ‘free license’ and run this program from the folder where CNCnetPDM is installed you get unlimited functionality. Otherwise you can only read data and execute commands that require no additional input parameter (x). Please see licensing for details or contact us if you have any questions.
Note: If you like to run this program from a different folder on your PC you can simply copy your CNCnetPDM.ini file to this directory.
