- Modbus-TCP
- Ethernet
- RS232
- RS422
- RS485
- Papouch Converters
TCP2RTU PoE is a transparent converter in both directions of the MODBUS TCP protocol, which runs over Ethernet, to the MODBUS RTU/ASCII protocol, which runs over RS232, RS485, and RS422 lines.
The converter is powered via an Ethernet cable using the PoE standard or a standard external power adapter. A power output terminal for external devices is also available. Both the converter and the connected device can be powered from PoE. The output can be enabled and disabled along with other parameters via the web interface.
TCP2RTU PoE is part of a durable metal design: a DIN rail mount can also be ordered as an accessory.< /p>
Operating Modes
- Modbus TCP > Modbus RTU: The master (TCP) on Ethernet addresses the slave device (RTU) on the converter’s serial port.
- Modbus TCP > Modbus ASCII: The master (TCP) on Ethernet addresses the slave device (ASCII) on the converter’s serial port.
- Modbus TCP Modbus RTU:
- The converter behaves as a Modbus RTU slave with Modbus ID configuration on the serial line.
- The data from the serial line in the Modbus RTU protocol is converted by the converter to Ethernet to the Modbus TCP protocol.
- The Modbus ID can be configured to 0, then the converter converts all received data to Modbus TCP on Ethernet, or to 1 to 247, and then the converter converts to Modbus TCP only the data for this set ID.
- Modbus TCP Modbus ASCII: Same as the previous case, except that the Modbus ASCII protocol is on the serial line
- HTTP GET: allows writing and reading data from Modbus RTU devices using http GET requests. For example, set.xml?id=31inst=4adr=123val=32752 writes with instruction code 0x04 to the device with ID 31 at address 123 the value 32752. This function will be added in the next firmware version. The function will also be uploaded to the current hardware version.
Properties
- Serial line converter in both directions with Modbus RTU/ASCII to Modbus TCP via Ethernet.
- Power supply via standard PoE (IEEE 802.3af) or from an external source (11 to 58 V).
- Power output for connected 5, 9, 12 or 24 V: can only be switched on and off via the web interface.
- The power supply is galvanically isolated from other parts of the device.
- Easy configuration via the web interface.
- Switchable RS232 or RS485 interface.
- RS232 used: RxD, TxD, RTS, CTS, GND.
- RS485 used: RxTx +, RxTx-.
- Indication of power, network data transmission, connection and activity.
