Siemens PCS7 uses CFC to implement functions; experts, please come in
Thread Content
As shown in the attachment, CFC. To achieve the following functionality: when P14405 is in automatic mode, P14420 (low pressure) activates the auxiliary oil pump P14405 ； Stop auxiliary oil pump P14405 due to high pressure P14419 ； I’m using an RS flip-flop. Using the pump function block in PCS7, I would appreciate some guidance from those who are more experienced – is there any bug or error in the CFC function block diagram in the attachment? Perhaps experts have different frameworks and approaches. This is my first time using Siemens PCS7; I would appreciate any guidance you can offer. It would be better if you could reply with a sketch. Thank you.
It’s best if you take a screenshot of this; otherwise, others will have to spend money to download it.
The screenshot has been uploaded. Thank you everyone
Why not use PCS7’s image library and dynamic wizard for configuration? The use of ‘m’ in PCS7 is relatively rare, and the local switching between manual and automatic modes for motor blocks may also need to be checked.
