Here is few descriptions: The rack for your S7-300 is a mounting rail. You can use this rail to mount all modules of your S7-300 system.The number of racks you need will depend on your application. Mounting order of the modules: Hang the modules onto the rail, starting at the left and in the following order: 1. Power supply module 2. CPU 3. SMs, FMs, CPs, IMs You should assign a slot number to each one of the mounted modules, thus making it easier to assign the modules in the configuration table in STEP 7. The table below shows the slot number assignment. Slot numbers for S7 modules: Slot numbers Module Remark 1 Power supply (PS) module – 2 CPU – 3 Interface module (IM) to the right of the CPU 4 1. Signal module (SM) to the right of the CPU or IM 5 2. Signal module – 6 3.Signal module – 7 4. Signal module – 8 5. Signal module – 9 6. Signal module – 10 7. Signal module – 11 8. Signal module – So, for example, if your CPU located in Rack 0, slot 2, you should specify these digits. For more detailed info please refer toS7-300 CPU 31xC and CPU 31x: Installation manual. |
