9.PMAC PC-Host computer send instructions

Usually we say PC controls other hardware work, refers to the PC to the corresponding hardware to send instructions to control the corresponding hardware. At the same time, after sending the instruction may receive the corresponding feedback message, tell the PC current hardware status and parameters and other data, this is the common PC and hardware communication. PMaC has helped us to encapsulate this communication process, directly call the relevant function, where the host computer to the PMAC to send instructions to control motor motion or set parameters or return the current specified parameter values.

PMAC provides Pmacgetresponse and Pmacgetresponseex to the PMAC to send instructions. This process is very similar to the terminal in which we manually send instructions to PMAC, where the two functions that support sending commands are also online commands entered in terminal.

Let's look at some of the simplest examples, add several buttons and their response functions to the dialog, and add code to the response function to do the following:

1. Setting parameters

<pre name= "code" class= "CPP" ><pre name= "code" class= "CPP" >//link Pcomm32.dll function library, Note the introduction of Myruntimelink header file Openruntimelink ();//Open PMaC Card connection openpmacdevice (0); TCHAR Szres[max_path]; TCHAR szcmd[max_path];/*****************************************************/lstrcpy (SZCMD, "p1=1");// Send instructions and receive a postback command to populate Szrespmacgetresponse (0,szres,max_path,szcmd);/************************************************ Close the PMaC card connection closepmacdevice (0);//freelibrarycloseruntimelink ();

2. Get parameter values

Link Pcomm32.dll function Library, note the introduction of Myruntimelink header file Openruntimelink ();//Open PMaC Card connection openpmacdevice (0); TCHAR Szres[max_path]; TCHAR szcmd[max_path];/*****************************************************/lstrcpy (SZCMD, "P1");// Send instructions and receive a postback command to populate Szrespmacgetresponse (0,szres,max_path,szcmd);/************************************************ Display the current parameter value AfxMessageBox (szres);//close PMaC Card connection closepmacdevice (0);//freelibrarycloseruntimelink ();

3. Control Motor Point Movement

Link Pcomm32.dll function Library, note the introduction of Myruntimelink header file Openruntimelink ();//Open PMaC Card connection openpmacdevice (0); TCHAR Szres[max_path]; TCHAR szcmd[max_path];/*****************************************************/lstrcpy (SZCMD, "#6j +");// Send instructions and receive a postback command to populate Szrespmacgetresponse (0,szres,max_path,szcmd);/************************************************ Close the PMaC card connection closepmacdevice (0);//freelibrarycloseruntimelink ();

4. Control program operation

Link Pcomm32.dll function Library, note the introduction of Myruntimelink header file Openruntimelink ();//Open PMaC Card connection openpmacdevice (0); TCHAR Szres[max_path]; TCHAR szcmd[max_path];/*****************************************************/lstrcpy (SZCMD, "&1b20r");// Send instructions and receive a postback command to populate Szrespmacgetresponse (0,szres,max_path,szcmd);/************************************************ Close the PMaC card connection closepmacdevice (0);//freelibrarycloseruntimelink ();

Note that the axis number and program number are consistent with the program you have written and downloaded.

See, in the/**/note is not very familiar with, in fact, we PEWin32 in the terminal window sent instructions, before and after the/**/is actually to establish and release the operating environment process. Many times, for the host computer program, we even need to call Pmacgetresponse and Pmacgetresponseex is enough to meet our needs .

5. Demo Program

For the overall presentation, let's integrate the above common functions into the following interface:

The corresponding operation code and the above demo code, here in order to demonstrate the convenience of each sending instructions to establish the environment and the connection to PMAC, send instructions, disconnect and release the environment, in the actual project, only need to re-instantiate or window instantiation when the environment and the connection of PMAC, Disconnect and release the environment when the window is closed or the program exits. The code is as follows:
