What components are required? | Siemens S7-300 guide

3.1 What components are required?

Note

If you do not have a motor, you can still implement the example. In this case, you will observe the LEDs on the digi- tal outputs of the CPU 312C.

3.1 What components are required?

In order to control the conveyor belt, you will need the components shown:

•Power supply for the control components

•CPU 312C with integrated input and output module

•Mounting rail for installing the modules

•Momentary contact switch

•Motor for driving the conveyor belt (optional)

•PC with STEP 7 Lite including Service Pack 2

•PC Adapter USB for connecting the PC with the CPU 312C
