I have KRC4 KSS 8.3.27 that is a profinet device of a Siemens S7 1500 plc that is profinet controller.
The datablok in the Siemens is sent as one consistent unit to the KRC4 (the whole datablok should be sent in one and the same PN cycle to the robot).
In the submit interpreter, I read in the IO of the communication with the Siemens.
Now I am concerned about the synchronization between the submit cycle and the update of the data by Profinet.
For instance I have ten Dint variables (32 bit integer) in the Siemens that I send to the robot.
I in a certain line in the submit interpreter I read in these ten variables, will they all be of the same PN cycle?
For instance, in the Siemens at moment 1 all ten variables are 0, at moment 2 in one plc cycle they are written with value 999. Can I be sure that all the ten variables in the the submit interpreter will be at 999 in the same submit interpreter cycle?
Is a submit interpreter cycle always executed from begin to end and never interrupted somewhere in the middle?
Thanks
