How to connect an Modbus Slave Simulator to Scada? can anyone tell me the software available to test this?

I have an Scada system developed in Wonderware for an interface of Fire and Gas Signal. Now in the Scada system Slave id 1 is defined for Gas system. here there are many registers .e.g 10261 to 10709. now without connecting the gas system i need to check the points are working fine.

i need an slave simulator software where i can change the values of register 10261 to 1 or 0. when it is changed to 1 an alarm needs to be generated in Scada. can anyone help me in this software where i can test the Scada using an Slave Simulator Software.

 

Hello,

Check out the free slave simulators at: http://www.peakhmi.com/

Good luck,

Calta produces a Modbus simulator package. A demo is available at www.calta.com.

 

Nishith,

Simply Modbus offers a Modbus Slave Simulator.

Here is a link to their website:

I have never used their slave simulator, but I have used their Modbus master (and client) simulators, and they work quite well.

 

Ruby with Modbus

you'll find similar systems on Python, all free and open source

i am considering same but also with cucumber and expect to write an automated test.
