We will now look at the Horner XL4 numbering system and addressing. Data is stored into different memory type locations called registers. The registers can be either bits or words (16bit). Multiple registers can be used together to store a 32 bit value. (Double word) This all in one controller has several additional registers to handle some of the HMI communication. Let’s look at all of the areas in the controller.
Cscape uses the conventional method of addressing similar to other controllers.
%[type][offset]
% - required character
[type] - register type - R, I, Q, etc. see below
[offset] - this is the address of the register
Example: %R33
Note: You can also use [offset][type] for the format. So 33R is the same as %R33.
This series on the Horner XL4 all-in-one controller (PLC) will go step by step through learning how to use this innovative unit.
