Product Description:
The 5A5000.01 is a plug-in storage and communications board manufactured by B&R Automation for integration into controllers within the 5A5 Hard Disks series. Mounted in an industrial PC backplane, the module provides local memory and fieldbus links so machine builders can archive recipe data and exchange messages between axes or external devices. In an automation cell it acts as a compact hard disk substitute while extending the controller with CAN and serial channels, enabling data logging, diagnostics, and security key management without extra peripherals.
The board occupies an ISA 16-bit slot, allowing direct memory-mapped transactions with x86-based mainboards at standard bus cycles. CAN networking is handled by an Intel 82527 controller that uses the CAN 2.0b standard, so the controller can send extended identifiers and use remote frames for parameter polling. Removable media is supported through the PCMCIA interface; the single slot accepts type I, II, or III cards and can operate in tri-state mode when the host bus is idle. For asynchronous links, the module incorporates a 16-byte FIFO per channel, reducing interrupt load when both serial ports stream data at higher baud rates.
The on-board backup cell uses a Lithium chemistry to maintain the real-time clock and safeguard the 256 kB of SRAM that stores recipes and fault snapshots during power loss. Both serial connectors can be switched between RS232/RS422 signaling, and they are electrically isolated to block ground loops. A single card slot limits the footprint, while the Dallas hardware security key sits on the internal LPT2 header so licensing cannot be removed from the front. This layout helps maintain stable communication when the board operates alongside other grounded devices in the same cabinet.
