Each slot reserves 4 bytes of address space, even if the module doesn’t use all of them. The starting address for slot n is (n-1) * 4 .
In the landscape of industrial automation, few platforms have demonstrated the resilience and longevity of the Siemens SIMATIC S5. While the newer S7-1200 and S7-1500 systems dominate modern greenfield projects, a staggering number of critical infrastructure plants—particularly in the power, water, and heavy manufacturing sectors—still rely on the robust architecture of the S5. siemens s5 hardware configuration

The main rack houses the CPU. It is always the master. There are two common sizes: While the newer S7-1200 and S7-1500 systems dominate
Let’s walk through the workflow of configuring a standard S5-115U centralized system.
Respect the S5. It ran the factories of the 80s and 90s with a reliability that modern IoT devices can only dream of. With a proper hardware configuration, it will run for another decade.
This is the most challenging part for newcomers. S5 uses . You don't assign symbolic names to I/O addresses; you calculate them based on slot position and module type.
