3.9 Creating a Configuration Diagram
After you have documented the design requirements, you must then decide on the type of control
equipment required for the project.
By deciding which modules you want to use, you also specify the structure of the programmable
controller. Create a configuration diagram specifying the following aspects:
• Type of CPU
• Number and type of I/O modules
• Configuration of the physical inputs and outputs
The following figure illustrates an example of an S7 configuration for the industrial blending
process.
