Formulate a scaling equation to program into the PLC so that 4 mA of current registers as 0 GPM, and 20 mA of current registers as 700 GPM. So all these parameters are going to be in a specific unit. A simple formula can be utilized to convert between these two units of measurement. 2 %âãÏÓ 24 0 obj /Linearized 1 /O 26 /H [ 762 255 ] /L 19424 /E 6473 /N 4 /T 18826 >> endobj xref 24 18 0000000016 00000 n 0000000707 00000 n 0000001017 00000 n 0000001171 00000 n 0000001296 00000 n 0000001522 00000 n 0000001701 00000 n 0000002125 00000 n 0000002200 00000 n 0000002632 00000 n 0000002841 00000 n 0000003932 00000 n 0000004106 00000 n 0000005692 00000 n 0000005929 Oct 12, 2020 · So If i wanted to scale an analog input on hard mode, I would do it in Directsoft 6. ) For example, an analog input with a range of 4 to 20mA has a decimal range of 3277 to 16384. If it is zero then omit it. These receivers allow for the transmission and In today’s digital age, we are fortunate to have access to advanced technology that allows us to capture precious moments on video. Understanding Analog I/O in PLC Systems Analog Input (AI) Modules Analog input modules in PLC systems allow the connection of sensors and devices that provide continuous analog signals.
