Hi All , I have seen this conversion which says Real to integer - But from my understanding The PLC does not know real values it store analog values inside its memory in bits bytes word and so on by converting them to bits .. so when we are using word real what does mean ? Suppose I am saving the INPUT from a analog module (0 TO 10 V ) to a Data Block then what type of memory it should be (word , integer , real ) I need to make this program which work like this , There is a Potentiometer which gives output from 0-10 volts into the analog input module , first i want to map this to a Data Block (When i create the Data block what memory type should I choose ) Now i want to scale it to 0-5 Volts DC and move to another Data Block from that DB i want to move it to the Analaog output module |
