Siemens SIMATIC HMI Smart 700IE V3

The Siemens SIMATIC HMI Smart 700IE V3 is a high-performance, cost-effective 7-inch touch panel designed specifically for the Asian market. It is part of the “Smart Line” family, engineered to work seamlessly with the Simatic S7-200 SMART PLC.

The V3 (Version 3) is the latest iteration of this series, featuring improved hardware, a faster processor, and better screen quality compared to the older V1 and V2 models.

1. Display and Visuals

• Screen Size: 7-inch Widescreen (16:9).¹

   

• Display Type: TFT LCD with 64,000 colors.

• Resolution: 800 x 480 pixels (WVGA), which is much sharper than older basic panels.

• Backlight: LED backlight with a long service life (approx. 20,000 hours), featuring adjustable brightness.

2. Connectivity and Ports

The Smart 700IE V3 is designed for modern networking but retains legacy support:²

• Ethernet Port (RJ45): Built-in 10/100 Mbps port.³ This is the primary way to connect to S7-200 SMART PLCs or other controllers via Siemens’ industrial protocols.

   

• Serial Port (Isolated): A 9-pin D-sub port that supports RS-232, RS-485, and RS-422. This allows it to talk to older PLCs or third-party devices using Modbus RTU.

• USB 2.0 Port: Located on the back, used for high-speed project downloads, firmware updates, or connecting a mouse/keyboard.⁴

   

3. Hardware Performance

• Processor: High-speed 600 MHz ARM processor, ensuring smooth screen transitions and fast data processing.

• Memory: Built-in storage for complex graphics, alarm logging, and historical data trends.

• Installation: Designed for horizontal (landscape) or vertical (portrait) mounting to fit different machine layouts.

5. Key Features

• S7-200 SMART Integration: Features optimized drivers for the S7-200 SMART PLC, making tag importing and communication setup very fast.

• Data Logging: Supports real-time and historical data trending, which is vital for monitoring pressure, temperature, or production speeds.

• Alarm Management: Sophisticated alarm system with support for alarm classes, history, and acknowledgment.

• Multilingual: Supports multiple languages, including English and Chinese, switchable at runtime.

Maintenance & Troubleshooting:

• Firmware Update: If the HMI displays a “Loader” screen or version mismatch, you may need to perform a “ProSave” firmware update using the WinCC Flexible SMART software.

• Touch Calibration: If the touch becomes inaccurate, you can enter the “Control Panel” during the startup phase to re-calibrate the screen.
