Serial Network Backplane and Deterministic Messaging
The terminal utilizes high-velocity backplane communication components to process point-to-point DF1 and multi-node DH-485 serial protocols directly via the built-in RS-232 interface. Supporting variable I/O density scaling through local PLC register mapping, the hardware offloads display rendering from the host controller. Flash firmware compatibility ensures stable execution of application files across Series A through E hardware revisions while maintaining high-speed screen updates under continuous operational polling.
Frequently Asked Questions
Q: What is the mechanical actuation rating of the front membrane function keys?
A: The stainless-steel poly-domed membrane keypad and function keys (F1 through F8) are rated for up to 1,000,000 actuations at an operating force of 340 g.
Q: Can the RS-232 communication port operate simultaneously with external USB peripherals?
A: Yes, the RS-232 serial port handles dedicated controller communication (DF1/DH-485) while the USB peripheral ports independently support external keyboards, mice, or flash memory storage devices.
Q: What is the operational input voltage window for the 24 VDC power connection?
A: The terminal operates within a DC voltage range of 18 to 30 VDC, drawing a maximum power consumption of 25 W at 24 VDC nominal input.
Field Installation Guidelines
- Cut the enclosure door panel cutout precisely to 123 mm x 156 mm before securing the unit into a NEMA Type 12, 13, 4X or IP65 environment.
- Maintain a minimum clearance of 50 mm around all sides of the housing to ensure adequate convection airflow and avoid internal overheating.
- Connect the functional ground screw on the rear chassis to the enclosure central ground bar using 14 AWG (2.5 mm sq) stranded copper wire.
- Route RS-232 serial communication wiring and 24 VDC power lines in dedicated wireways, keeping them separated from high-voltage AC circuits and drive output leads.
