What does C5S2U mean in the diagram? And what is L? Why are some lights green while others are red?
I haven’t come into contact with it before, but from the content of these images, it’s clear that the green light indicates power supply to the circuit board, while the red light signals that a fuse has blown； As for C5S2U, it is the identifier within your system
This is the cable number from the signal acquisition terminal board in the Maslin cabinet to the controller

Since all TRICON cards, except for PI and AO cards, are 32-channel cards, each card corresponds to two terminal boards; Upper refers to the terminal board for the first sixteen channels, while Lower refers to the terminal board for the latter sixteen channels. The green light is the power indicator, and the red light is the fuse status indicator
The image shows a DI card; the information on the 5th floor is quite comprehensive
I have a few more questions: why does this lamp with the DO terminal turn red, while the others remain green? And for physics: does the 1 in 1.5.4 represent the rack?
Red light: The power terminal may be disconnected, so no power is being supplied. The relay is connected to electrical signals and does not require external power supply. Green light: The knife switch is closed, for example, when it is connected to an on-site solenoid valve or something similar. External power supply is required. 1.5.4 Rack/Module/Channel
