Context: Mitsubishi Q series
Hi, today I configured an analogue input into the PLC.
Then I injected 4-20mA at the terminal block. The digital value on the PLC showed 0 at 4mA & 4000 at 20mA, as expected.
This value is going to represent a water flow in m3/hr.
I need to convert it into these units. I know that at 4mA this equates to 0m3/hr, and 20mA equates to 100m3/hr.
Question... where's the best place to do the conversion? In the ladder logic or maybe "hidden" in the details of the digital display of the flow rate on the HMI GUI ie in GT designer3 (which is linked to the Data register, in my case D45).
Hope that makes sense. If not,.I will try to clarify. Thanks.
