How to integrate two controllers of different vendors to synchronise the motion

[hisham21@yahoo.com]

We have intended to synchronise the motion of X-Y linear positioning stages with the motion of precision press actuator. These machines supplied by different vendors and came with their stand alone controllers and their platform software controls. However, each controller has digital I/O which can be used to extraxt the digital signal for external devices. I am looking advice for the simple way to integrate these controllers and to develop synchronising motion of these machines...appreciate your comment thank you

It would be helpful to know more about the driver stages you use. Do they have their own feedback loop, i.e. do they use rotary or linear encoders and have their own position control? If so, is it possible to route the encoder drivers to the NI controllers?
