Hello sallesa,
The PM.llb is only to check if the PH600 motorized micropositioner is moving. I have included in this email another .llb within which there is a .vi called PA200_GPIB.vi. This vi should give you a good starting point for your coding project. If you like the coding style you can use this vi. The basic structure is using an enumerated type, which is type defed, to store the commands for each axis, I do not have all of the commands stored into these typedefs so you may need to add the ones you need. You can get all of the info you need by opening the Remote Communicator under the SUSS Prober Bench application, and selecting commands\kernal\chuck\ReadChuckPosition etc. Once the command is in the command window of the Remote Communicator, you can place the cursor over the command, click on the command, and hit F1 to get the help for that command, this is for version 4 of SUSS Prober Bench. If you plan to use other GPIB instruments, you will need to dedicate a controller to the PA200 since it will not coexist with other instruments on the GPIB bus.
Hope this helps,
Karl
