- The PLC exchanges data via the fieldbus/Ethernet network
- The converted serial data from the Communicator can be accessed by the PLC
- The Communicator collects data from the devices on the serial sub-network
- The data is stored in its memory buffer before an intelligent conversion takes place
- The Communicator reads and writes the serial telegram to the serial device via Modbus-RTU, ASCII/DF1/CAN or other custom based protocols
- All data between the fieldbus and the serial network is stored in an internal memory buffer inside the Anybus Communicator.
The Results
The internal storage of I/O data inside the Communicator de-couples the two networks.
This permits the that even automation devices with slow serial communication can be integrated into high-speed fieldbus/Ethernet networks without any restrictions to the upper network.
