SET UP
21.1 Modbus menu
21.1.1 Modbus server gateway
This gateway allows to connect asynchronous modbus
slaves to the serial interface of the IPRS.
• Select the modbus menu and then modbus server and enable the modbus server gateway and set
the parameters as follows :
“Port selection” parameter :
Select the serial port COM 1 or COM2.
If the modbus server gateway is assigned to one serial COM port, it cannot be assigned to the other
one.
« ASCII / RTU protocol » parameter:
Select the right option
“Proxi” parameter:
Enable the proxi option if you wish to avoid to frequent requests on the RS232-RS485 interface.
“Cache refreshment period” parameter:
Select the period at which the gateway will send request to the slaves PLC.
“Timeout waiting for the answer” parameter:
Set up the timeout the gateway has to wait for the answer of the modbus slave answer.
“Local retry” parameter :
Set up the number of times the gateway will repeat a request before declaring a failure.
“Inter-character gap” parameter :
Set up the maximum delay the gateway will have to wait between a received character of a modbus
answer frame and the following character of the same frame.
“Modbus slave address” parameter:
Choose “specified by the modbus TCP client” , if the address of the slave PLC must be decoded by
the gateway from the modbus TCP frame coming from the client.
Otherwise, specify the modbus address of the slave PLC; in that case only one slave can be
connected to the RS232 serial interface.
“TCP inactivity Timeout” parameter :
Set the time the gateway will wait before disconnecting the TCP link if no characters are detected.
