PLC and control in one panel. I/O according to your task.
HORNER XL4 PRIME combines PLC, 3,5″ color touch screen and five physical buttons. You control a small machine or fixture and monitor operating values from one place. You can choose from six designs: from the model without built-in I/O to variants with digital, analog and temperature inputs.
Standard Cscape for both PLC program and HMI screens is free with each panel. You do not buy a programming license. Optional communication and web features have their own license and firmware terms.

Verify XL4 PRIME on your own task.
Free loan of selected products for 14 days is arranged individually according to availability. We will confirm the specific model, date and conditions in advance. FOXON will help with the selection and the first project.
Introducing XL4 PRIME
The Horner short product video introduces the XL4 PRIME and its basic equipment. English.
Applications in small machines and systems
Pump switching according to time or event
Starting at a specified time, running for a set time or reacting to a level and other input signal. The operator sets the values and sees the pump status on the display.
Controlling a small machine or fixture
Starting the work cycle, continuity of individual steps and counting of pieces. The operator changes the length of the step or the number of repetitions on the panel.
Measurement and simple regulation
Display of pressure, temperature or other quantity and reaction to the set limit. The sensor type and signal range must match the selected built-in or extension I/O.
Local equipment monitoring
Input states, error messages and common settings on one display. You can prepare the range of screens and controls according to the specific device.
You create a function for your technology in Cscape. Select the necessary sensors and control elements according to the device.
Trial loan and training
Free loan by agreement
Free loan of selected products for 14 days is arranged individually according to availability. We will confirm the specific model, date and conditions in advance.
Training in Liberec
We train individuals and groups in our training room in Liberec. We will agree on the scope and date according to the experience of the participants and their tasks.

Selection of variant XL4 PRIME
Select the design according to the list of signals. The HEXP251C100 is the 0 model without the built-in I/O. Codes HEXP251C112 to HEXP251C116 indicate models 2 to 6 with different combinations of inputs and outputs. Prices and availability are listed above.
HEXP251C100No built-in inputs and outputs.
For control over a communication interface or with suitable expansion I/O.
HEXP251C11212 digital inputs, 6 relay outputs and 4 analog inputs (12 bits).
For tasks with relay contacts and measuring 0-10 V or current signals.
HEXP251C11312 digital inputs, 12 transistor outputs and 2 analog inputs (12 bits).
For control with transistor outputs and two analog signals.
HEXP251C11424 digital inputs, 16 transistor outputs and 2 analog inputs (12 bits).

HEXP251C11612 digital inputs, 12 transistor outputs, 6 universal analog inputs and 4 analog outputs.
For multiple analog and temperature signals as well as output values.
We will advise you on the selection of a suitable design and accessories according to the project.
Signal types and wiring limitations
The numbers and types of I/O relate to a specific order code. HEXP251C100 does not have a built-in I/O. 2, 3 and 4 models support analog inputs 0-10 V, 0-20 mA and 4-20 mA. Choose 5 or 6 for direct measurement of Pt100 and thermocouples. The analog channel mode must match the jumpers and configuration of the Cscape. The voltage and current terminals of the same analog output are not two independent channels. Quick features share selected digital channels. Check the connection, signal combination and current limits in the datasheet of the exact design.

Your first test task
When first verifying, start with one simple function. For example, an output that switches on for a set time after pressing a button or changing the input signal.
- Set the switching time on the display and show the input and output status.
- Handle the trigger condition and timer in the program.
- On the test load, verify switching on, switching off after a time has elapsed and changing the settings on the display.

Frequently asked questions
Do I need separate PLC or HMI?
XL4 PRIME contains both PLC and touch HMI. You do not need separate PLC and HMI for the same task. Built-in I/O depends on the code: HEXP251C100 does not have them, models 2 to 6 have different combinations of signals.
What is free and what is charged separately?
Standard Cscape is free with each panel. You can create the PLC program and the HMI screens without a paid programming license. Additional features have their own license terms. Free loan of selected products for 14 days is arranged individually according to availability. We will confirm the specific model, date and conditions in advance. Accessories, training and the work of technicians will be priced according to the scope.
Which design to choose for Pt100 or thermocouple?
For direct temperature measurement, select universal analog inputs of model 5 (HEXP251C115) or model 6 (HEXP251C116). We will compare the sensor type, number of channels and connection with the datasheet of the selected design.
How to decide between XL4 PRIME and CANVAS 4?
Compare the necessary signals, graphics, communication and any existing project. Both models have a compact 3,5″ display and buttons, but differ in the graphics system and conditions of extended functions. We will help you choose a model for a specific technology.
Can you assess migration from an older XL4?
Send the full order number of the original panel, version Cscape and available project. We will verify the I/O configuration, assembly, communication and the necessary modifications to the project.
How can I check trial loan availability?

VIDEO: Tips and tricks for setting up HORNER PLCs with display, inputs and outputs
HORNER PLCs combine machine control, operator display and inputs/outputs in one device. If you need a compact solution for a smaller machine, part of a production line, a test station or modernization of older equipment, you do not have to source and combine a separate PLC, HMI panel and I/O modules.
The manufacturer’s training videos show how to connect the panel, work in Cscape, set up communication, use WebMI and work with basic inputs and outputs. They are especially useful during initial commissioning, so you do not have to figure everything out by trial and error.

Review: Cscape Software for Horner PLCs with Integrated HMI
For efficient work with Horner panels (PLCs with integrated HMI), you need a reliable and intuitive programming tool. The Cscape software allows configuration of both the PLC and the integrated HMI within a single environment—and it’s free. Once again, we asked specialist Jaroslav Blažek (blaja.cz) to take a closer look at the software. You can find out how the installation and registration went in his review.
