Siemens SIMATIC HMI KP300 Basic Mono PN

The Siemens SIMATIC HMI KP300 Basic Mono PN is an entry-level, keypad-operated panel designed for simple HMI tasks.¹ It is part of the Siemens Basic Panel line and is specifically engineered for use with PROFINET networks, making it a perfect companion for the S7-1200 or S7-1500 PLC series.²

The “KP” stands for Keypad, and the “PN” stands for PROFINET.

1. Display and Visuals

Despite being a monochrome display, the KP300 features a unique multi-color backlighting system that allows for visual status signaling.³

• Screen Size: 3.6-inch.⁴

   

• Display Type: FSTN LCD (Monochrome).⁵

   

• Resolution: ⁶$240 \times 80$ pixels.⁷

   

• Backlight Colors: You can program the backlight to turn White, Green, Red, or Yellow. This is highly effective for alerting operators to alarms (Red) or warnings (Yellow) from a distance.

2. Interface and Operation

This is a non-touch unit. All interactions are handled through high-quality tactile buttons:

• Function Keys: 10 freely configurable function keys (F1–F10) with tactile feedback.⁸

   

• Alphanumeric Entry: Numeric keypad layout similar to a mobile phone for entering setpoints and text.⁹

   

• Durability: Physical keys are often preferred in environments where operators wear heavy gloves or where the screen might be subject to splashes.

3. Connectivity and Communication

• PROFINET (PN): Features 1x RJ45 port (10/100 Mbps). It uses the industrial Ethernet standard, allowing for easy integration into existing office or plant networks.

• Software: Programmed exclusively via WinCC (TIA Portal). It is supported in the “Basic” edition of WinCC, which is the most affordable version.

4. Technical Specifications

5. Key Advantages

• Cost Efficiency: One of the most affordable HMI solutions in the Siemens lineup.

• Compact Footprint: Ideal for small control boxes or “local” control stations on large machines.

• Global Compatibility: Supports a wide range of languages, including Asian and Cyrillic character sets.

• TIA Portal Integration: Being part of the TIA Portal ecosystem means you can share tags directly between the PLC and HMI, significantly reducing programming time.¹²

   

Maintenance Tip:

If the HMI is not appearing in your TIA Portal “Accessible Devices” list, ensure that you have set a compatible IP Address and Profinet Name on the device itself. You can do this by entering the “Control Panel” on the HMI screen during the boot-up phase.
