Using the MintMT ActiveX Control 4-3

The following examples are in Microsoft Visual Basic:

MintController.doUpdateFirmware “C:\MintMT\Firmware\nmPCI.CHX”

will update the firmware on the controller with the file nmPCI.CHX from the path C:\MintMT\Firmware.

The update firmware function will use the handle created using the set…Link function and pass the

firmware to the controller via the appropriate communication channel.

4.4 MintMT programs

The MintMT ActiveX control can be used to download and run compiled MintMT programs to controllers.

During development MintMT programs are stored in a ASCII text format as a .MNT file. To run this on the

controller it must be compiled into an executable format using WorkBench v5. Within WorkBench v5,

rather than running the program select the Tools - Program - Compile to File menu option. This will

produce a Mint executable file (.MEX).

The MintMT executable file can be downloaded to the controller using the function

doMintFileDownload. This function accepts a string that is the path of the file including the file name

and extension.

For example, where MintController is the name of the MintMT ActiveX control in the project.

The following examples are in Microsoft Visual Basic:

MintController.doMintFileDownload “C:\MintMT\Programs\myMintProgram.MEX”

Will download the file myMintProgram.MEX from the path C:\MintMT\Programs

If the firmware on the controller and the Mint executable file are incompatible an error message will be

displayed. The version of MintMT running on the controller must be compatible with the version of the

compiler used to compile the MintMT executable.

Version details of the .MEX file can be obtained before it is downloaded to the controller using the version

locator utility on the Baldor Motion Toolkit CD.

Once the program has been downloaded to the controller it can be run using the function doMintRun.

Calling this function will run the MintMT program immediately. Execution of the current program can be

halted by calling the function doMintBreak.

4.5 Mint Motion Library function calls

Motion applications can be written on the host PC by calling Mint Motion Library functions via the MintMT

ActiveX control. The MintMT ActiveX control uses the immediate command mode (ICM) interface to

communicate with controllers. The ICM interface is a packet based communication protocol that allows PC

based applications to call MML functions on the controller. The MintMT ActiveX control will create, send,

receive and decode ICM packets to allow complete machine control via a PC based application.
