Figure 10-48 Motion Control/Isochronous drive link with PROFINET, optimized cycle with CACF = 2

Sequence of data transfer to closed-loop control system

1.Position actual value G1_XIST1 is read into the telegram image at time TIO_Input before the start of each cycle and transferred to the master in the next cycle.

2.Closed-loop control on the master starts at time TCA_Start after each position controller cycle and uses the current actual values read previously from the slaves.

3.In the next cycle, the master transmits the calculated setpoints to the telegram image of the slaves. The speed setpoint command NSOLL_B is issued to the closed-loop control system at time TIO_Output after the beginning of the cycle.
