1. Engineering Workstation - where you create your programs/FBD, etc.

2. Operator Workstation - monitoring and operation only, some call it as HIS/HMI

3. Network Communication - to communicate your workstations and field control stations

4. Field Control Stations - that's where your field control units are installed
