I have a Modbus RTU device with address =1. This Modbus device using address #1 then is connected to a RS485 to TCP-IP converter. The address of this RS485 to TCP-IP converter is using IP address 192.168.17.7. My laptop is using 192.168.17.51. May I know where I should set my IP address 192.168.17.7 of RS-485 to TCP-IP converter within Administrator side?
Where I should set as Modbus RTU or Modbus TCP here?
The mode should be Modbus RTU, but the communication line setup should be TCP/IP with the port specified from the converter settings. At the same time, the device Address = 1 must be specified in the device settings
Again, may I know if I have to pay Modbus Slave driver here? Or this application is not related with Slave driver here. If this is the case, I will be noted on this.
To communicate with a Modbus device you need a Modbus driver that is included in Rapid SCADA by default. While Modbus Slave driver is used in special rare cases.
