In the S7-300, the main control cabinet uses IM360, while the expansion cabinets use IM361. IM360 is the data transmission block, while IM361 is the data reception block. How should we understand this concept of transmission and reception?

His description is incorrect; communication is two-way. You just need to remember that the rack where the CPU is located must use IM360, while other expansion racks must use IM361.

Can CPU errors be handled online? ~~

What specific error is it? What’s your configuration? More detailed information is needed to answer.
