PLC Training - SLC 500 Scaling - Part 2

[cybersoul2008]

HEy can you explain the Scaling? what is the function of this scaling in control and what is the example of output this scaling? sorry i'm new and study of the PLC program

@cybersoul2008 Sure, scaling is generally used to convert the information coming from(or to) analog cards into something meaningful to the user. For example a temperature transmitter may be wired into an analog input card. The transmitter sends a signal to the PLC analog input card which in turn converts that signal to a number for the PLC. Those numbers are not usually meaningful to us users (ie, ranging 0-16387). We use scaling to convert that to something meaningful to us - maybe 32-212 F
