Hello, experts. I have a few questions: 1. Is the second diagram showing the connected state? 2. What device is indicated by the arrow in the third diagram? 3. Please introduce the general process of the first diagram. Thank you.
1、Not connected； 2. What is P131 (pressure)? I don’t know Values representing different stages; I’ve seen this used for time relays before, and it’s possible that different values are output to trigger actions at P135 values of 2030 and 2031. 3. The process is unclear and the legend is incomplete

Hello expert, I have another question: 1. Do the two red boxes each represent a module? 2. Also, does the double-dotted broken line indicated by the arrow represent the identifier of the module? 3. Where do P81 and P2227 come from or go to respectively? Thank you for the reply.
