Hardware Configuration Link - Siemens S5

Many plants are migrating by replacing the S5 CPU with an or ET 200SP CPU in a new rack, but keeping the S5 I/O modules alive using an IM 153 interface module. This requires reconfiguring the S7 hardware, not the S5—but you must first fully document the S5 configuration to know which addresses map to which physical terminals.

S5-135U and S5-155U are large, rack-based controllers designed for complex, high-speed, or redundant tasks. 2. Central vs. Expansion Racks A typical S5 system is built on a backplane or "rack." Central Controller (CC): siemens s5 hardware configuration
