Moving PTO positioning axes of an S7-1200 as IO device centrally from an IO controller (S7-1200/S7-1500)
The "LPTO" library enables you to control up to 4 positioning axes of a S7-1200 as an IO device centrally from an IO controller (S7-1200 or S7-1500).
By means of a pre-configured device CPU, you can rapidly put the remote axes into operation.
In the device CPU, 4 "TO_PositioningAxis" technology objects are configured, which use the S7-1200’s 4 pulse generators to control 4 servo motors via a train of pulses, PTO (PulseTrainOut).
Using the I-device communication, you can move and monitor the remote axes from the controller.
This means that you can, for example, use 8 pulse generators (4 local and 4 remote) with an S7-1200 as an IO controller to centrally actuate 8 servo drives.
