Click plc - Analog output programming

2 posts in this topic

Hi all,
We have a machine to produce corrugated aluminium sheets that acts as space in the ERV cores. The finish sheets must have the following attributes:
  1. Aluminium to be corrugated perpendicular to the direction of travel of the material within the machine.
  2. Sheets with range in width from 165mm to 762mm
  3. Sheets with range in length ()with corrugation) from : \
  1. without perforation 165mm to 1800mm
  2. with perforation: 450mm to 750mm
  1. Corrugation height (pitch) will range from 1.5mm to 6.0mm
Right now the machine’s pressure is calculated manually using the pressure gage. Our goal is to replace the pressure gage with digital regulator.
My question is how to calculate the pressure equation for this machine?
I came up with this formula P= width size* Constant (CONSTANT = coefficient of foil aluminium = 2.2/100000), but unfortunately this formula did not work well. It gives me very high value!
I am using click plc to program the regulator and c-more micro to program the HMI.
Any suggestion or feedback would be appreciated and thank you for your support in advance.
