ABB AC500 V3 - AC500;S500 System Structure

S500 devices represent the I/O modules of the product group AC500 (Standard), whereas
S500-eCo devices represent the
I/O modules of the product group AC500-eCo. Both S500 and
S500-eCo devices can be flexibly combined with devices of the AC500 product family.
3.2 AC500/S500 system structure
The AC500 product family provides a variety of modules and pluggable components for
expanding the capabilities of the processor module with additional I/Os or other communication
protocols. Depending on the features and functions of the processor module (CPU) compatible
components can be added to a complete AC500 PLC system.
01 Terminal base for processor module and 0 to 6 communication modules, with serial and
Ethernet interfaces
02 Communication module for, e.g., PROFIBUS, EtherCAT, and for support of safety solution
03 Processor module with integrated communication
04 I/O module, up to 10 I/O modules can be connected
05 Terminal unit for I/O modules, also for decentralized extension
