What I'm interested in understanding is the sequence of system activities triggered upon receiving a new packet. In systems like Linux, for instance, a new packet typically generates an IRQ interrupt, which must then be processed by a CPU. This often results in an interruption of the application currently running on that CPU, unless you're using a real-time operating system and have customized your system accordingly. Is there a similar mechanism in place here? Suppose I have an OB running with priority 5, and I receive a packet associated with another OB with priority 1. While my OB with priority 5 wouldn't be interrupted by the OB with priority 1, would it be subject to interruption by a hardware or communication interrupt responsible for checking and processing the incoming packet? Would anyone happen to know of a comprehensive documentation resource that I could read? Thus far, I've come across this S7-1500 Response Times. It has been helpful in understanding the various response times. However, I'm still seeking clarity on the specific system activities that are triggered upon receiving a new packet. Thank you very much in advance. |
