2. AC500-eCo Hardware Descriptions
2.1 CPU Overview
The CPU PM554 and PM564 is the central unit of the AC500 system with the onboard
digital/analog inputs and outputs. The CPUs can be powered by 24V DC or 100-240V AC
depending on different variant.
The different between two CPU types is the onboard I/O type.
Each AC500 CPU PM554 and PM564 can be used as
Bus Master within the control System AC500 together with CS31 or/and Modbus;
Stand-alone CPU.
