Dear Godra ,

Thank you for replying.

For this PLC actual have 2 physical serial port.
1. name as tool port on the PLC software.-> Connected to the PC for PLC live view-> on PC side via COM13.
2. name as COM1 on the PLC software.-> Connected to the PC for advance HMI -> on PC side via COM9.

So both connection use different serial com cable / port for communication.

Hi all,

Thank you for this great software.
I am trying to connect Panasonic FP0R-C32CT PLC via RS232 to Advance HMI via ModbusRTUCom1.
I have tried initial steps to build & basic gauge / label and indicate correct COMport Settings between Advance HMI and PLC side.
But i am unable to get any counting data from the PLC to the Advance HMI even though the PLC realtime data itself have data.
 
i attached some snippet of the settings for analysis.

Hi Godra,

Thanks for the link,

is there any way to just use ModbusRTUCom.Write(400003, txtFinalOutput.Text) without getting an error "ModbusRTUCom is not declared" in VS2019 ?

Hi,

I am trying to make the VB.Net send the value to PLC (Panasonic FP0R)
If i am using Basic Button or Basic Label, it works.
But if i am using below code, ModbusRTUCom is not declared error came out on Visual Studio 2019

ModbusRTUCom.Write(400003, txtFinalOutput.Text)

I trying to declare as below just for testing, but no data register changes on the PLC.
 Dim driver As New AdvancedHMIDrivers.ModbusRTUCom
            driver.Write("400003", "1")

Any idea ?
