Position on the Local Rack

Every M580 standalone SIL3 safety system requires one BME•58•040S CPU and one BMEP58CPROS3 coprocessor (Copro). The CPU requires two module slots and is placed in slots 0 and 1 immediately to the right of the power supply in the main local rack. The Copro also requires two module slots and is placed in slots 2 and 3 immediately to the right of the CPU. Both the CPU nor the Copro cannot be placed into any other slot locations or on any other rack. If there are extended racks in the local rack configuration, assign address 00 to the rack with the CPU and Copro.

NOTE: Both the safety CPU and the Copro can be installed only on a BMEXBP•••• Ethernet rack. For a description of available M580 racks refer to the topic Local and Remote Racks in the Modicon M580 Hardware Reference Manual.
