Hello Sir, I am not able to find real to real conversion, word to real conversion in s7-300 software, can you tell me where you took from it, and also tmpscale is temporaryreal variable, how did you assign the variable? How we use for scaling(FC105) in ladder language in s7-300, i am going to use control water tank level, when water level is above 20%, pump Q0.0should be run,when its reached 90%, pump Q0.0 should be off. Splitted from Trouble with 4-20mA scale. |

Hello, What do you mean whith "real to real conversion"? Check there How and for which analog measurements can you use the function FC105 "SCALE" to convert the integer values (INT) into real number values? Scale the level. And then make a comparisons in order to activate start/stop output depends from the actual level. Best regards, Hristo MIhalev |

If you want to convert Word Value to real Value, then First move Word Value to INT Value, convert INT to DINT, and then DINT to Real
The use of Scaling Block has been told by Mr. UMENCHO. Once you get the Real Value, Use comparator blocks to make Q0.0 ON/OFF |
