Product overview
The WoMaster HE7 is an all-in-one HMI PLC integrating a 7-inch touch screen with a programmable logic controller. It supports STEP 7-MicroWIN SMART and S7-200 SMART instructions, and provides multiple wired interfaces for machine and system integration.

Key features

• Integrated 7-inch TFT touch display (800 x 480) for local operation and visualization
• STEP 7-MicroWIN SMART compatibility (S7-200 SMART instruction set). Exclusions: certain wizards (motion/web/data logging/PROFINET) and specific communication library items
• Opto-isolated digital I/O with positive/negative trigger support
• High-speed counters and dual high-speed pulse outputs for motion and counting applications
• Built-in real-time clock with power-off data retention (replaceable button battery)
• Multiple communication ports: Ethernet (PLC & HMI ports), RS485 (2 ports), USB; supports S7-TCP, PUT/GET, OUC, MODBUS TCP/RTU, PPI, USS and free-port modes
