Product Description:

The PP2MB1/3 is a motherboard stage from B & R Automation within the PP Motherboards series. Serving as the central processing board inside Power Panel operator terminals and other compact controllers, it hosts the CPU, memory, and I/O connectors needed for machine visualization and sequence control. By integrating computing resources on a single PCB, it supports compact panel designs and reduces the need for separate processing hardware in distributed industrial automation nodes.

At its core, the board carries a Geode SC2200 processor that runs at 266 MHz, providing x86-compatible instruction support for the Automation Runtime operating system. Working RAM is supplied by 64 MB SDRAM, allowing local data buffering, recipe handling, and HMI graphics. Nonvolatile program storage is delivered through 2 MB of onboard flash, while frequently updated variables reside in 256 kB of SRAM so they survive warm restarts. A 4 MB shared graphics frame buffer renders screen content without requiring a discrete GPU, and one Type I CompactFlash slot accepts removable media for software loading or log retrieval. Two sixteen-position mode and node rotary switches permit address assignment directly on the panel.

Network and service interfaces are concentrated along the front edge. An RJ45 jack presents a 10/100 Mbit/s Ethernet channel for PLC programming or SCADA traffic, while a male nine-pin port supplies an RS232 serial link for legacy devices and service access. Two USB Type-A receptacles conform to the USB 1.1 standard and provide host connections for a keyboard, mouse, or storage devices. The real-time clock is maintained by a Renata 950 mAh lithium cell, and a capacitor-backed circuit provides a 10 ms power-failure buffer so the controller can complete task shutdowns during a brief loss of input power.
