Simotion D
The program tool is Scout, browse the device online in Accessible nodes to determine the type and version of the device, otherwise it can’t be online.
UDP communication protocol is adopted. Build a new project and create a ST_1 program. the model and version number must be correct, otherwise it can’t be online.

END_PROGRAM END_IMPLEMENTATION
Adding program ST_1.pda to low priority task such as BackgroundTask, the fastest period can be set to one servo cycle, it is also available to other task such as ServoSynchronousTask, but it is easy to cause Simotion D to stop when the sending cycle is too short, it may be avoided by calling the error program.
Run or stop Simotion D.
Connect or download or disconnect Simotion D.
The PDA configuration corresponding to the data sent above is below, the byte should be swapped.
Download without HW configuration.
Add global variable to watch table, whether it is consistent with the PLC program may be checked.
Check whether it is consistent with the PLC by means of hardware online.
