Hi, I just bought a Modbus slave driver, I tried to connect Rapid SCADA with a third-party PLC which works as the MODBUS RTU Master, the line is working good, and I can see there is data receiving and sending, but I can’t see anything value on device tags.
the settings are below. can someone please help me fix this?

Hi,
Do you need to take values from another device connected to Rapid SCADA?
If so, choose a configuration approach:
Approach 1
Do not create input channels for Modbus Slave device.
Just specify “Data source device” in the device properties. This is a number of the device that collects data from real equipment.
Modbus template tags must match the source device channels. It’s handy if you translate a Modbus master device to Modbus Slave.Approach 2
Use the channels for JAZZ SLAVE you already created.
Set channel formula, for example,Val(101); Stat(101)
where 101 is the source channel number.Note: we plan to simplify the driver settings in the future.
Thank you for your reply Mikhail,
what I wanted to do is just to create a virtual modbus slave device inside Rapid Scada, then I can send values from a real Modbus master device to this virtual slave device and simply display those values in Rapid Scada. could you please give me more instructions on how to do that?
Regards,
Ming
