Product Description:

The 4MP181.0843-03 mobile operator terminal is produced by B&R Automation within the 4MP Mobile Panels series. It is a handheld interface module intended to bring visualization, parameter entry, and acknowledgment functions directly to machinery without a fixed cabinet-mounted screen. Through an integrated TFT display and touch surface, users can monitor process variables, initiate machine sequences, and perform diagnostics while remaining beside the equipment. This portability shortens setup time and supports troubleshooting in automated conveying, packaging, or assembly cells.

The panel uses a Geode SC2200 processor that runs at 266 MHz. This embedded CPU works with 64 MB SDRAM to host the visualization runtime and fieldbus drivers without delays caused by external storage access. Graphics are rendered on an 8.4 in TFT color screen that delivers a native resolution of 640 × 480 pixels, which is sufficient to present detailed alarm lists and schematics on a compact surface. Image clarity is supported by a contrast ratio of 250:1 and a luminance of 120 cd/m², so the contents remain readable under typical factory lighting. Analog resistive touch technology allows gloved operation, and a Hampshire Serial 12-bit controller converts finger pressure into cursor coordinates for the control application.

For system connectivity, the integrated MacPhyter DP83816 Ethernet controller links the panel to PLC networks at 10 or 100 Mbit/s, while a serial COM1 port supports point-to-point diagnostics up to 115 kbit/s. Removable data can be loaded through a Type I CompactFlash slot or the front-accessible USB 1.1 interface for service keys. The electronics draw from a nominal supply of 24 VDC, which simplifies cabinet power distribution. Backlight output is specified to fall to half after 50,000 h, which suits long operating intervals for factory HMIs.
