Seeking assistance regarding the function blocks of Hilscher MACSV system
Thread Content
Interlocking is required on-site; the condition is to detect the operating status of the pump from the previous cycle. Could some expert advise me on which function block can be used to determine the operating status of the pump from 48 hours ago?
Why do this? The operating status of the pump can be checked in the trends anyway What is the purpose?
Was the status 48 hours ago involved in interlocking?
You don’t mean to have the pump run for 48 hours before it stops automatically, and then start again automatically after 48 hours, right?
Let me draw a diagram for you; without software it’s not possible to do this practically, and the drawing won’t be very good, but just take a look
Run Pump A the first time, and run Pump B the second time; switch in this way
The original poster’s description is incorrect; this is the switching control of a pump, and the core of its control lies in interlock control combined with timed switching control.
Are there several pumps, and is the one that runs for the shortest time the one that gets activated? . Looking at this diagram, is it just a pump?
