1. Typical application Address IP2 4 t i 1 2 Protocol modes Converter can work in two modes Transparent mode Ethernet TCP IP lt gt RS 485 mode and Modbus TCP lt gt RTU mode In Transparent mode received data string ASCII or binary format from Ethernet network is transferred to RS 485 port without any changes Similarly received data string from RS 485 port is transferred to master device but only when network connection with converter is open In Modbus TCP lt gt RTU mode Modbus TCP data frame is converted to Modbus RTU frame Modbus RTU is standard protocol for control and measurement devices equipped with RS 485 port Converter has got internal buffer 300 B for receive and 300 B for send data For RS 485 port user have to configure transmission speed and parity in compliance with device configuration 1 2 1 Transparent mode In this mode there are three typical types of communication between master system and device available User have to be sure to setup proper value for Response Timeout for his type of communication 1 Master Slave communication Converter receives from Ethernet client a query sends it to the device via RS 485 port and starts Response Timeout timer If response appear before the timeout end then it is send to the client which sent query When the response appear alter the timeout end then it is send to all connected clients If a new queri2.
