PCS 7 BRAUMAT Library – process tag types
BlVlvL
2.10 BlVlvL
Valve with one control output (open/close) and two feedbacks
This process tag type can be used for valves with Open/Close position with the APL block VlvL.
•
The feedback signal of the valve is read from the I/O through Pcs7DiIn driver blocks.
•
The interlock signals of VlvL are connected to the IntLk02 interlock blocks. These interlock blocks in
turn are connected to other blocks, for example, to digital process tags via Pcs7DiIn.
•
The digital output signals are sent to the I/O through the PCS7DiOu blocks.
•
In unit simulation mode, the feedback signal is generated from the adapter block (delayed on
demand)
