3.3 AC500-eCo/S500-eCo system structure
AC500-eCo/S500-eCo series is compatible with AC500/S500.
The compact AC500-eCo processor module can be used for small applications with the inte-
grated I/O channels.
The functionality of the processor modules can be extended with option boards, e.g., for addi-
tional I/O channels.
For larger applications, I/O modules can be connected centralized or decentralized.
