Beckhoff Twin-CAT

[fergy]

Has anyone of you ever used the Beckhoff Twin-CAT Software to control

Stepper Motors (or DC-Servo) and sucessfully implemented it into Labview,

to handle instructions ?

I am looking into this configuration, but i have only two souces: one says

yes, it's only little problem, the other says no....

Thank you,

One approach would be to develop code for the Beckhoff PLC to control the steppers (KL2531 slice(s) required) and then use the Labview as an HMI to send high level commands to the PLC. In this configuration the PLC waits for Labview to populate a few memory locations with info such as direction of rotation, how many steps, a GO bit, etc. Once the GO bit is set, the PLC starts the motion and a Done Bit should be set when the movement has completed.

I personally haven't done it but this would be my first approach.

Hope it helps,

PS. 1. Are you thinking about a hardware or software PLC?

2. If a hardware PLC is usedwhat kind of communication interface do you plan to use?
