This is the display when Modbus TCP mode is selected for COM2 (RS485).
It shows that the source port number of serial communication device to server.
”502”, the standard of Modbus TCP (RTU), is recommended.
Note) The same port number can not be set for COM1 and COM2. Set the main serial port for Modbus
TCP connection to “502” and set the other port to another number.
When “502” is set to COM1, set “9095” to COM2 and when “502” is set to COM2, set “9094” to
COM1. And confirm that there is not the port number repetition from a client.
KS1 Signal Converter can connect 3 devices as RS232C server and 3 devices as RS485 server. Max
connected devices as server side is 6 connections.
When some devices are connected as server, set Timeout time. When no signal from one server after
setting timeout time, signal converter cut the connection with the server and wait for the next
connection.
Default setting is 60sec.
Note1) In case of setting “60”,it cut TCP connection when there are no communication for 60 seconds,
after establishing TCP connection.
2) KS1 Signal converter keeps the connection until time out setting time after establishing TCP
connection if the client cut TCP connection correctly.
Set the timeout with considering break of Ethernet cable, cut out TCP connection due to power
discontinuously of the unit and the case when it can’t establish connection.
When the client connects a new connection during KS1 Signal converter connection, it connects
max 3 connections for one port.
3) In case of setting “0”, it keeps TCP connection until passing two hours with no communication
(After passing two hours, the connection will be opened.)
