System components A SIMATIC 505 controller consists of a processor in a local base together with a power supply and I/O cards. With the SIMATIC 575 controller, this is a 16 slot VME bus base together with a power supply and up to 8 total controller CPUs, the remainder of VME bus slots can be filled with I/O cards or other VME bus compatible systems. Expansion I/O bases can be added to the system by adding additional bases, power supplies, remote base controllers, and I/O cards as required. Moreover, at least one communication processor is required per SIMATIC 505 controller. This communication processor should be installed in the local base together with the controller CPU
