Control.com - Nerds in Control

Hi all,
i'm pretty new in this field.
For university purpose i have to develop a IDS (or maybe just some short rules) for scada systems.

so i was wondering if there is any software that can help me to simulate PLC-> HMI communications and vice-versa (if possible in modbus).

can anyone help me in that?

thank you in advance.

Hi,

For modbus communication you can use the Modsim from www.win-tech.com

Hello,

have you seen flexmodbus?
You can find the project at: https://sourceforge.net/projects/flexmodbus/

But however you need a modbus server. For this purpose you can use "Free Modbus Simulator".

You'll need a master and a slave. best bet is ModSim and ModScan. Both are very easy to use.

both can be found here.

If you are developing your SCADA system on .NET platform, then I prefer to visit to www.parijat.com

They have many device drivers for various protocol communication.

They are giving 300 transactions limit in demo mode, which is well suited for test purpose.

Also , they are giving, example project for help purpose.

So, you can download MODBUS TCP/IP Slave, MODBUS TCP/IP Client application from their website.

Thanks,

You can download KEPServerEX and us the Modbus Suite. The Modbus TCP driver can be used in slave mode and you can read and write to the Modbus registers with its test client (OPC Quick Client) and also you own client. The server supports OPC DA, OPC AE, OPC UA, OPC .Net, iFix Proficy NIO, Wonderware SuiteLink, DDE, and NetDDE out of the box.

There is not tag limit in demo mode and the demo mode (2 hrs) can be restarted by saving your work, stopping, and restarting the server.
