OPC communication issues with HaliTech DCS
Thread Content
Hello, everyone. I would like to ask you all a question. We currently have an Allen-Bradley DCS, as well as a simulation platform that creates simulation models of the actual process. The DCS is equipped with an OPC Server and OPC clients, which allow data from the DCS system to be read; however, data can only be written to the handheld operator unit, not to the data collected at the site. Now I want to use OPC to connect the DCS and the simulation model. The main issue is how to configure the database on the DCS side so that OPC can write field data. I hope the experts can help me out; I would be extremely grateful!! ! ! ~
OPC does not provide write access to all parameters. Hollyland seems to have its own dedicated OTS operator training system; it doesn’t seem to be based on your approach.
Really! :'(Our teacher asked me to use this for semi-physical simulation; we use Apros as our simulation platform, and I find it difficult to work with – I don’t know how to do it.)
Where? I can look for someone from Rockwell Automation to help you answer your questions
In Chongqing, the main issue is that the AI points in the database configuration cannot be written to – only read is possible – while the analog values AM can be both read and written to. But I don’t really know how to call the AM point in the controller algorithm configuration.
