Dear Friends,

I am stuck on the problem i dont know what to do and where to start.

I have one device called Monitoring system and i want to communicate with that device through my PC/Laptop and set data , i am confuse how to start or what to do or where to start.

I need to create GUI for that to communicate with machine/device.

About machine :
The machine/Device can send data via MODBUS to the external devices like DCS / HMI through MODBUS vis
communication module.

Please suggest where to start and which language i need to choose.
What question i need to ask to my client.

Warm Regards,
Sagar

Thank you Paul for your reply,

Problem is i want to implement this in programming language so you user can access over internet.

I have two option to implement this
1st J2EE
2nd PHP

But i am not finding any way to implement this in J2EE or PHP (Main problem is speed , i want to show this within 2 or 3 sec in graph format)...

Please guide.

1) I will have to create two columns in MYSQL database and insert data in that, each column contain 8-9 k data.
2) Then i need to plot this data in chosen GUI in three separate plots on one screen as shown in attached image.
3) Time interval for X-axis for plotting individual graph is 0.001.
4) Then i need to plot these two waveform data against each other as XY graph as shown in graph.
