Embedded PLC Application Kit from Rabbit

Posted in Development Tools, Zilog, PLC, SBC
On Saturday, November 4, 2006

The Rabbit Embedded PLC Application Kit supports industrial programming languages such as; Sequential Function Chart (SFC), Function Block Diagram (FBD), Ladder Diagram (LD), Structured Text (ST), and Instruction List (IL) and Flow Charts (FC).

The Kit gives you everything you need to get started programming a Rabbit Semiconductor SBC with the ISaGRAF PLC programming system. Included in the kit is the BL2500, an advanced single-board computer that incorporates flash memory, SRAM, digital I/O ports, analog I/O, RS-232/RS-485 serial ports and a 10/100baseT Ethernet port.

The BL2500 single-board computer provides control and automation engineers with a powerful and low-cost embedded solution, suitable for high-volume applications such as factory equipment control, access control, HVAC, and vending machines.

The BL2500’s compact board size of 100 x 100 mm is easily mountable in standard 100 mm DIN rail trays. External connections are provided via polarized friction locking connectors, enabling rapid assembly using wire harnesses.
