AS-Interface

AS-i is an open, manufacturer-independent bus system that organizes the transmission of digital and analog process and machine signals into the control system. The AS-i Master communication module, as the "heart" of the AS-i Fieldbus can record sensors in the field or control actuators in the field.

The connection of an AS-i network to the SIMATIC S7-1200 is quite simple: the AS-i Master CM 1243-2 communication module is simply plugged into the CPU and wired to the field. The AS-i Master CM 1243-2 thus connects the lowest field level, such as IO modules, position switches, signaling columns, load feeders and motor starters with the higher-level SIMATIC S7-1200 control system. For each master, up to 62 AS-Interface slaves can be connected. All the advantages of the TIA Portal apply, such as the fully graphical parameter assignment and diagnostics of all AS-i stations without additional software.
