Hi guys
I have Cisco IR809 and would like to set modbus gateway to convert ModbusTCP packet to ModbusRTU that direct attached on interface async 0.
MODBUS/RTU(Slave)------------(rs485)----------IR809---------------(ethernet)------------MODBUS/TCP(Master)
I tried to use raw-socket but it look like when the Slave receive message it is MODBUS/TCP message, it shows bad CRC. I think the Cisco809 have to convert the TCP to RTU. I tried to read the solution of IOX but I can not fine the work configuration and code.
Please help..:)
