Timers and counters are used in the majority of PLC programs. We will not look at how timers and counters can be programmed in the Horner XL4 OCS all-in-one controller. Continue Reading!
We will now look at the Horner XL4 user interface. The HMI (Human Machine Interface) part of the XL4 all in one controller will be what the operator views. We will look at the features of the display and learn how our program will control what the display will show. Continue Reading!
We will now look at the Horner XL4 numbering system and addressing. Data is stored in 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. Continue Reading!
The Horner XL4 OCS all-in-one controller is programmed using Cscape. Cscape (Control Station Central Application Programming Environment) We will now set up the Cscape software so we can easily communicate and program our controller. Continue Reading!
