How to send and recive data to Delta PLC in .net?

pare-es · Dec 29, 2014

I have a delta plc that want to send and recive data from it.
I use this code for open serial port.

Code:

  SerialPort port = new SerialPort("COM1",9600, Parity.Even,7, StopBits.One);   port.Open();   port.WriteLine("???");

I have a VB6 code that send data to Delta PLC.

Code:

var_60 = ":010313F50002F2" var_28 = Chr(13) var_58 = ":010313F50002F2" & var_28 & Chr(10)

I want to send this to Delta PLC, How do send this data to plc with .net?

I hope you know Modbus protocol and .net programming .

You have various options .

Archie's Advanced HMI found on this forum has everything you need.
