6.3.3 Process-Related meaning of the "CFC_FC111" CFC chart
CFC_FC111
CFC_FC111 is used to control the dosing quantity and dosing speed. In this case, the blocks
mean the following:
● The "Pcs7AnIn" block provides the currently dosed volume at the "PV_Out" output and
transfers this measured value to the "PV (process value) input of the "DoseL" block.
● The "PIDConL" block delivers the manipulated variable of the flow.
● "DoseL" delivers the setpoint for the flow (manipulated value for the "PIDConL" block) and
checks the dosing quantity.
● The manipulated variable for the valve is sent to the "MV" output of the "PIDConL" block.
Then, it is fed to the "MV_Trk" input of the "PIDConL" block in the absence of manipulated
variable feedback from the process.
● The "Pcs7AnOu" block sends out the manipulated variable to the valve.
6.3.4 Process-Related meaning of the "CFC_LI111" CFC chart
CFC_LI111
CFC_LI111 is used for controlling and simulating the fill level. In this case, the blocks mean
the following:
● The Pcs7AnIn" block reads the fill level of the raw material tank and outputs the current
value at "PV_Out" output.
● The "PV_Out" output is interconnected with the "OutTrk" input of the "Integral" block.
● The "Out" output is interconnected with the "PV" input of the "MonAnL" block.
● The "Mul04" block is used to simulate the quantity which is taken from the reservoir at the
given point of time.
6.3.5 Process-Related meaning of the "CFC_NP111" CFC chart
CFC_NP111
CFC_NP111 is used for pump controlling. In this case, the blocks mean the following:
● The "Pcs7DiIn" block supplies the current state of the pump - on or off, at the "PV_Out"
output.
● This value is interconnected to the "MotL" input (feedback ON) of the "FbkRun" block where
it is evaluated.
