Hi,
So both analog and digital are inputs to the PLC from the Flow Meter,
If this is correct and the digital input does'nt have to be used, you can use only the Linearization block without the ADD block, and you will get the input from the Flow Meter every scan
How to create a linearization (example is attached):
The Linearization setting (also in the attached image):
1.First you have to check the resolution of the specific PLC(in the SPEC), for example the V350-35-R34 is 10-bit and it will be,
0-1024, so X(1)=0, X(2)=1024.
2.Y(1) and Y(2) will be the units from the device itself, for example 0-100.
3.In X you will set the register that getting the inputs from the device.
4.In Y you will set the output of the from the ‘Linearization’ block.
*If it is still not clear, you can share the device SPEC,
