Master PLC Mastering Instructions: Quick Guide [Tutorial]! 🪜 on the PLC. Step-by-step tutorial with real-world examples.

⚡ QUICK ANSWER
Modbus on the PLC maps remote coils and registers into local memory. Choose the port (Modbus RTU over RS-485 or Modbus TCP over Ethernet), match baud/parity/slave-ID on both ends, then use a read/write instruction to move holding registers and coils between devices.
