How AS-P communicates with the IO modules.

AS-P and IO modules communicate on internal Communication bus which enables serial (RS-485) communication between them. The AS-P server controls and supervises the communication on the communication bus. The Central IO modules also monitor their communication status. When a new Central IO module is configured and connected to the I/O bus, the automation server automatically detects the new Central IO module.
