Hi All, We are new to using scada ignition software. We are building a device simulation on AWS and nseed to push the data generated from the simulation into ignition database via OPC-UA. Does anyone has any thought on this ? It is very urgent and need suggestions/guidance

Do you have any example code for simulation to support OPC UA ? So that we can build the same interface in our device simulation code ?

No… I don’t have any code for you. You haven’t really provided enough details even if I did. If you want to add OPC UA support to your simulation the best approach would be to find an OPC UA SDK for whatever language you’re using to build it in.

thank you. I am writing my simulator in python. Does OPC UA SDK provides OPC UA for python ? Do you mean to say, the simulator we are developing should implement as OPC-UA Client ?

Your simulator should implement an OPC UA server. You can then connect Ignition to it and read, write, or subscribe to the data it provides.

My simulation software is going to work as a device (like sensor/PLC in real world) sending data to OPC-UA server so that ignition can be used to design dashboard. This is what i thought. Isn’t it not correct ?

You’ve got the data flow backwards. Devices don’t typically push data to the OPC UA server. The drivers in an OPC UA server poll data from devices. Your simulation device will have to support some protocol that Ignition’s OPC UA server has a driver for. Or you can skip that extra layer all together…

Instead of exposing simulation data via OPC UA you might find it a lot simpler to expose it via Modbus (so, your device acts as a Modbus slave). Then you could connect Ignition’s Modbus Driver to it. The downside would be there’s no browsing with Modbus, but the upside is it would be much easier for…

thanks Kevin for giving different options in sending simulator data into ignition. Let me brief about our use case. We are developing a pressure vessel simulator (like physical device connected to PLC) on aws cloud and we have already installed scada ignition software (mysql as database) on aws clo…

Ahem. Consider using my Ethernet/IP Class1 Communications Module . While not really intended to be used this way, it basically is a complete simulation of an Allen-Bradley Logix PLC’s data table within Ignition. You can write jython code called from Gateway Timer Events to simulate the periodic ta…

the hyperlink given in your response is not taking to the right resource. Can you give me the correct url ?
