On the PID flowchart of the instrument, what does HIC-0902 mean? H stands for manual, I stands for indication, and C stands for control. So does this mean manual control indication? Does that mean that when controlling it, signals need to be manually entered in the control room? I earnestly ask experts for their guidance! Thank you! !
It’s impossible to determine just from a tag number; you can take a screenshot and show it.
I checked some information; the initial letter H only means manual.
It means manual operation; only the valve position value or switch command can be entered
There is such control. It’s best to make the decision based on your manufacturing process
The topic name should ideally indicate its meaning; for example, it would be good to clarify what HIC_XXX refers to
Remotely manually control the valve and provide feedback signals
Your understanding is correct; it’s a joystick with feedback functionality.
I have a question: how can one tell from here that more feedback is needed? This of mine is part of the water-carbon ratio control scheme diagram for a hydrogen production device; I can’t understand it. With everyone’s guidance, I understand that it’s necessary to manually enter the water-carbon ratio and then make adjustments, but I really can’t see any indication that feedback is required! Please give me some advice! Thank you for your answer! ! !
