In Zhejiang University’s ZHKong DCS, how can a signal be divided and sent to two different locations?
Thread Content
I currently have a neutralizing axe equipped with two circulation pumps. Initially, only one signal was provided for starting and stopping these pumps; now, both circulation pumps use the same signal to reset and stop simultaneously. I need to be able to control them separately. How can this be achieved? The interlocks are already in place, but I need to be able to control these two pumps independently. What should I do?
"What does a dot \"mean?\" So there is only one DO, which is then used to control the two pumps separately? It doesn’t start and stop at the same time?
Our company also deals with DCS, but I’m not involved in instrumentation, so I don’t know much about it. We can control 5 computers simultaneously.
Install one DCS first, and then connect another DCS from the output card. Just copy the signal in the program
Could you explain it in more detail? Currently, my two circulation pumps use the same signal for resetting and stopping them simultaneously; I need to be able to control them separately. How can that be achieved? The interlocks are already in place, but I still need to control these two pumps at the same time. What does it mean to control them separately?
The problem description is not clear enough; I’m not sure what you want to do, what goal you aim to achieve, or what kind of control you want to implement. It’s fine to define just one point for direct reference.
There is only one DO, so you can’t control them separately.
Enter the system configuration and create another start/stop program; add dialog buttons to the flowchart, otherwise separate control cannot be achieved
Theoretically, there is nothing that cannot be done; it depends on how you go about it and what the cost of implementation will be. Could you please clarify your question?
The problem isn’t clearly stated, but it can definitely be done. I hope the requirements and current situation can be explained in detail.
