Horner XL4 User Interface – All In One
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.
Horner XL4 Numbering System and Addressing
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 … Read more
The 7 Essential Parts of a PLC System
We will now look at the parts of a PLC system. When I was in school PLCs were just in their infancy. We were taught that the PLC consisted of the central processing unit (CPU), analog and digital inputs, and outputs. Everything was programmed with dedicated handheld devices and/or software devices on specialized hardware. We … Read more
Horner XL4 Establishing Communication
We program the Horner XL4 OCS all-in-one controller by using Cscape. We will now use our Cscape software to establish communication. Last time we customized Cscape with icons to make it easier to find, communicate and control the unit. There are two different ways to communicate to the XL4 OCS controller, Ethernet and Serial. There … Read more
Horner XL4 Cscape Software Setup – All In One
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.
Horner XL4 Installing the Software Cscape
The Horner XL4 OCS all-in-one controller is programmed using Csape. Cscape (Control Station Central Application Programming Environment) This single programming software package is designed to be easy to use and maintain. We will now install this programming package onto our computer.
Horner XL4 System Hardware – All In One
The Horner XL4 OCS is an All-in-one controller. This means that this modern unit combines a logic controller, operator interface, I/O and networking all into one package. This OCS (Operator Control Station) family was first released in 1998. New features to the line-up have been added over the years. Today the OCS family has a … Read more
