🔍 Key Concepts

• Compare how devices are physically connected to the PLC in diagram A versus in diagram B and C • Understand the difference between a shared communication path (where many devices tap into one main line) and individual dedicated lines from a central unit • Recall typical shapes of common topologies: bus, ring, and point‑to‑point / star‑like connections

💭 Think About

• Look at whether the sensors and actuators in A share a common main cable, or whether each has its own separate connection back to the PLC • Ask yourself: if one cable to a single device is cut, would that necessarily stop communication to the others in this topology? What does that suggest about the type of network? • Compare the diagram in A with what a classic bus network looks like (one straight line with drops) and what a ring network looks like (closed loop). Which does A resemble least/most?

✅ Before You Answer

• Verify whether there is one continuous trunk line with devices branching off, or multiple individual lines running directly from the PLC • Check if the devices in A form any kind of closed loop around the PLC, which would suggest a ring • Confirm whether each field device in A appears to have a direct, dedicated link back to the PLC rather than sharing a common highway
