Modbus TCP
If the econ sens3 is used as Modbus slave over TCP/IP, the Modbus TCP specification suggests the
port number 502 for use. Other values are possible.
Modbus RTU
If the econ sens3 is used as Modbus slave over RS485, the serial interface parameters are required.
Modbus gateway
If the econ sens3 is used as Modbus gateway, all parameters are required.
The Modbus TCP specification suggests use of port number 502. Other values are possible.
If the Modbus gateway receives a query over TCP/IP with a non-proprietary Modbus address, it will
function as Modbus server. In this way, a device can serve simultaneously as both gateway and
server. All queries with a different Modbus address are sent to the RS485 bus.
The TCP delay is the time in milliseconds after which the gateway sends a query to the RS485 bus.
During the TCP delay, no new requests are placed on the TCP/IP input. This functionality is
deactivated by setting the TCP delay to 0.
The RS485 timeout is the time that the gateway waits for a response over the RS485 line. If no
response is received within this time, it sends an exception code 0xB “Gateway target device does not
respond” to the master. 0 deactivates this function.
