TCP2RTU: MODBUS TCP to RTU/ASCII Converter
TCP2RTU is a transparent both directions converter of the MODBUS TCP protocol, running over Ethernet, into the MODBUS RTU/ASCII protocol, running over RS232, RS485 and RS422 lines. TCP2RTU works both directions since version 1.4. Either as a Modbus gateway (Master) or as a Modbus Slave.
TCP2RTU has been produced in three versions according to the type of the communication line for MODBUS RTU/ASCII. Configuration can be made over the internal WEB interface.
The following picture shows an example of a system communication the MODBUS TCP and RTU protocol.
