HMI Real data Scaling in GX IEC Developer.

hi I have to take input of weight from HMI as real data type and after scaling into INT compare it with the input feed back from analog input channel . how can I do that. does real data handling possible in FX 1n plc?

FX1N can do real numbers. If the data from the analog module is integer, then you need to convert one value or the other. Comparison must be done with the data in the same format. Choose 1. 1. Convert the value from the HMI to integer. The command is INT. 2. Convert the value from analog to real number. The command is REAL. Then perform your comparison, either on integers (like >, <) or floating point (E>, E<).
