Could you help me in my project
I need to make interfacing between Arduino Mega and PC via Win cc
What is the proper shield to this interface known that the distance between the shield and the PC is about 100 meters?
What is Win cc ?
This is way too wide.
Why are you doing this?
What is your experience?
What have you down with the Arduino so far?
Scada is inputs,outputs, analog i/o, data collection and may include SER.
You want to do all this?
You will need to break your project into manageable units.

Thanks for your reply.
I already do many industrial projects using PLC LG and its SCADA.
Recently I made small application using Arduino Mega and now I need to make this interface but my experience with Arduino as a beginner make me ask this quetion
We need to know what problem you are having.
Suggest you start with a block diagram of what you need to include.
I have an Arduino Code that simply calculates encoder counts, All I need to know is what I need to display this value on SCADA
ieee488:
What is Win cc ?
WinCC is a Siemens SCADA
When you're doing your control of your remotes how fast your control has to be
what type of control resolutions do you require
what type of control inputs do you require
what type of control resolution do you expect to have

Stop using SCADA in your sentences.
Tell us exactly what has to be done.

I need to display the encoder counts instantaneously on PC software
No control required from this PC software (just monitoring)
If these are rotary encoders they can be monitored as here.
An Arduino Mega has 4 serial ports.
The Arduino can send serial data to the PC via the USB cable or an FTDI interface.
You will need to folllow the serial protocol that the PC application uses.

Which interface do you recommend as the PC will be about 50 meters from Arduino PCB??
If you can help me which shield could I get ?
It's cool watching you all get stumped. What ARD_BH wants is stated right in the OP. Sometimes, there just isn't another way to phrase it. To summarize:
How to interface and Arduino Mega to the Win CC SCADA running on a PC 100 meters away?
As for what it takes to connect an Arduino to Win CC, FactoryTalk View, or Intellution I don't know. These systems use an OPC server on PC side and a driver specific to communicate to the controller. You would need to implement the OPC slave in the Arduino. I have seen some "Industrial Arduino" models> I wonder if they have the necessary software to be the client side of the OPC.
I don't know of a shield that would provide the OPC connection, only the serial protocol between the PC and the Arduino. The software will need to be part of the Arduino Mega program.

No. The question was not properly formed and asked.
You think it is funny that we "are stumped"? ? ?
It is not Scada. It is SCADA = Supervisory Control And Data Acquisition
I once interviewed at an optical device company where this SCADA engineer who previously worked at Exxon thought it appropriate use SCADA concept for a test station rack with test equipment and a PC.
.
I am sorry if I get you stumped, as I am very confused about which hardware shield needed to complete my project.
I am sure adwsystems, that I will need to focus on OPC more and more to interface my arduino to wincc.
so, we know that you do not want SCADA, but rather DA or Data Acquisition.
break down the project :
encoder, just one, a simple 4 wire ? this is where a DataSheet is needed.
output of encoder
input to circuit
circuit connects to Arduino
Arduino counts encoder changes.
we can help with that easily.
now you have a PC that is 500 to 1,000 meters away.
do you want to use wires ? RS485 is one place to look
can you use the internet ? WiFi might be an option
is RF a possibility, outside, not in a plant with noisy signals.
line of sight, laser ?
is this time critical ?
since control was ruled out, that relieves a lot of the problems and narrows the goal to a simple signal.

Basically from the looks of it, one runs an OPC server on a PC which interfaces both with the Arduino and with WinCC.

also appears to only work with an older version of the Arduino IDE
