Benefits of technology

[0024] The present invention may be embodied as a system for moving an object comprising a motion control device, an application program, a computer processor, and a data exchange system. The application program identifies a predetermined set of data items associated with the motion control device. The computer p

Problems solved by technology

While this approach does isolates the application programmer from the complexities of programming to each hardware configuration in existence, this approach does not provide the application programmer with the ability to control the hardware in base incremental steps.
The software driver model currently used for printers and the like is thus not applicable to the development of a sequence of control commands for motion control devices.

example 1

[0326] The first example illustrates how the language driver 44 might deal with the Driver function IXMC_DrvExt_Test::Move. [0327] Cmd Format: D%d,+:@[snd]GO%b+:@[snd][0328] Rsp Format: @[crlf]>@[rcv]@[crlf]>@[rcv][0329] Driver function Call: pXMCDrvExtTest→Move(20.0, 30.0)

[0330] This function call directs the motion control device to move 20 units in the x direction and 30 units in the y direction.

[0331] The driver communicates with the stream as follows:

[0332] Step 1. Perform the operation in the command format template up to the first @ symbol. This builds a raw command string of “D20.0,30.0:”

[0333] Step 2. After the first @ symbol is the send command, which sends the string that was built in step 1. The language driver has now reached the G in the command format template.

[0334] Step 3. After the send command, the language driver reads a response from the stream to confirm that the command string was received and processed correctly. The response string received from the stre...

[0339] The second example illustrates how the language driver 44 might deal with the Driver function IXMC_DrvExt_Test::SetVelocity. [0340] Cmd Format: V%lf,+:@[snd][0341] Rsp Format: @[crlf]>@[rcv][0342] Driver function Call: pXMCDrvExtTest→SetVelocity(NOP, 22.0) [0343] Explanation Set the velocity of the y axis to 22.0. [0344] Raw Command String: “V,22.0:”[0345] Raw Response String: “\r\n>” (expected)

example 3

[0346] The third example illustrates how the language driver 44 might deal with the Driver function [0347] IXMC_DrvExt_Test::GetVelocity. [0348] Cmd Format: GV%b+:@[snd][0349] Rsp Format: %d,+@[crlf]>@[rcv][0350] Driver function Call: pXMCDrvExtTest→GetVelocity(NOP, &dfY_Vel) [0351] Explanation Get the velocity set for the y axis. [0352] Raw Command String: “GV01:”[0353] Raw Response String: “,44.0\r\n>” (expected) [0354] dfY_Vel=44.0

Abstract

A system for moving an object comprising a motion control device, an application program, a computer processor, and a data exchange system. The application program identifies a predetermined set of data items associated with the motion control device. The computer processor is in communication with the motion control device and the application program to operate the motion control device by sending control commands to the motion control device. The data exchange system updates the application program when any of the data items in the predetermined set of data items changes.
