Horner XL4 Firmware Update – All In One

We will now look at changing the firmware on our Horner APG XL4 controller. The firmware update will give users the newest version of the operating system which adds new benefits to the controller. The firmware update is also required when changing communications between CsCan and CANopen. CsCan is a peer-to-peer network by Horner Electric based upon the Can network. CANopen is a communication protocol industry standard used in the CAN network.
Changing firmware will remove all programs and settings in the controller. Ensure that you have a backup of your information. Please refer to the release notes for the features that will be set with the firmware update.

Horner XL4 HTTP Web Server – All In One

The Horner APG XL4 all in one controller through the Ethernet port can set up a HTTP server. This HTTP (Hypertext Transfer Protocol) server can be used for distributed and controlled information presented to and from the controller to the network. The server can have security for the information presented. We use HTML (Hypertext Mark-up Language) on the server to create this Client / Server communication. Using the program on the process tank application we created previously, we will be controlling and displaying information to the network. A web browser on a computer, tablet, smart tv, or phone can be used to view and control this information in our Horner APG XL4 controller.

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 of the HMI communication. Let’s look at all of the areas in the controller.
