Saving constant to memory location
« on: November 02, 2015, 03:33:39 PM »
I'm working on a temperature control application and haven't done PLC programming for a while so rusty. I'd like to save the temperature set points to a memory location so they can be viewed and changed from the display on the DL06. I'd load default values initially that can be changed by the operator.  I need to be able to read the memory location out to compare to the current temperatures. I've been trying to load (LD) the constant (K690) to the accumulator and then OUT to a memory location but can't find a memory location that the program will accept and that I can read out.

Any help is appreciated.

After typing 'OUT' and pressing Enter press the '/' key (under the question mark) to change it to an OUT to a word (V memory) type instruction.
An output is a PLC's way of getting its inputs to change.

the same '/' key also will toggle a contact between NO and NC. It will also cycle through the inline compare type instructions. A versatile key.
