What is an operator panel?
Operator panel — is a specialized Human-Machine Interface (HMI) device designed for operator interaction with industrial equipment. It serves as a link between a person and an automated control system, enabling monitoring and adjustment of process parameters. Modern operator panels are compact devices with a display and input controls that are installed directly on control consoles or mounted in automation cabinets.
Historically, the development of operator panels has evolved from simple text displays and indicator lamps to modern high-resolution multi-touch screens. This progress reflects the overall trend toward improving the informativeness and ergonomics of industrial process control.
Types of operator panels
By interaction interface type:
Button operator panel is equipped with physical buttons for interaction with the system. It is distinguished by high reliability and durability, making it an ideal choice for operation in harsh industrial environments. Button panels allow operators to work even while wearing gloves and are resistant to various contaminants. They are especially in demand at facilities with aggressive environments, high dust levels, or increased humidity.
Touch operator panel provides interaction with the system through screen touches. Its main advantage is an intuitive interface and flexibility in the arrangement of control elements. Touch panels are particularly effective in situations that require quick switching between different screens and functions. Modern models may support multi-touch gestures, expanding the capabilities of controlling complex systems.
By display type:
Monochrome operator panel is equipped with a single-color display, usually blue or green on a black background. It is an economical solution for standard monitoring tasks and features a long service life.
Color panels have displays capable of showing a wide range of colors. This improves data visibility and informativeness, allowing the use of color coding for quick recognition of equipment statuses and alarm signals.
By communication capabilities (RS 485 / RS 232 / Ethernet)
Panels with RS 232 / RS 485 interfaces provide reliable data transmission and network communication at industrial facilities. These protocols perform well over long distances and in environments with strong electromagnetic interference. RS 485 (Modbus RTU) is especially popular due to its ability to create networks with multiple devices and its high communication line noise immunity.
Panels with Ethernet interfaces allow devices to be integrated into modern enterprise network infrastructures. This opens opportunities for remote monitoring, data collection, and integration with higher-level systems. Support for standard network protocols such as Modbus RTU / TCP, OPC UA, and HTTP ensures compatibility with a wide range of software and equipment and enables simple network communication.

Modern operator panels are programmed using specialized software provided by the manufacturer. These development environments usually feature a graphical interface and extensive libraries of ready-made elements, simplifying the creation of user interfaces. The programming process includes several stages and parameters:
- Development of screen structure and navigation system
- Creation of graphical elements and mimic diagrams
- Configuration of communication with controllers and other devices
- Programming event processing logic and responses to operator actions
- Testing and parameter debugging
- Downloading the completed project to the operator panel
Many modern programming environments support operator panel emulation on the developer's computer, allowing interfaces to be tested before downloading them to a real device. The availability of RS 485 and RS 232 protocols makes it possible to create a reliable working network, while protection during operation reduces the likelihood of network errors.
Examples of Operator Panels
Samkoon Touch Panels SPLC-SK Series
The SPLC-SK series includes models with display sizes ranging from 4.3 to 15.6 inches. The standard configuration includes an Ethernet port and three COM ports (RS 232 / RS 422 / RS 485) for data exchange. This panel supports additional expansion modules such as Wi-Fi and 3G modules for remote communication with controllers. The software for interface and parameter programming is SAMKOON Tools. The manufacturer is the Chinese company SAMKOON.
Monochrome Panel SPLC-OP320-A-S
This model is a compact panel featuring a monochrome graphic LCD display and 20 function buttons on the housing for changing values during operation. The panel includes backlight control settings. It is equipped with RS 232 / RS 485 interfaces and is compatible with most PLCs from various manufacturers. Parameter changes can be protected with a password. This panel is also known as IP320. Connection to the PLC is made via a DB9 cable, which is available in our online store.
Frequently Asked Questions:
