Introduction
1. INTRODUCTION
1.1 WHAT IS EMBEDDED PLC?
The EMBEDDED PLC system turns a Rabbit-based controller, such as the Coyote BL2500 Single-Board-
Computer (SBC), into a high performance and yet inexpensive Programmable Logic Controller (PLC).
The Target PLC can be programmed using the EMBEDDED PLC – ISaGRAF? Workbench in any of the
standardized automation control programming languages IEC 61131-3:

EMBEDDED
PLC – ISaGRAF Workbench becomes an alternative to Dynamic C to program Rabbit-based
controllers.
The EMBEDDED PLC system consists of two parts:
?
?
The Target PLC : A SBC BL2500 powered with the RabbitCore? module RCM3200 (Rabbit 3000
microprocessor, 44.2 MHz clock speed, 512K Flash, 256K Battery-backed SRAM, 512K Fast SRAM
and 10/100BaseT) and loaded with the EMBEDDED PLC Firmware Kernel (or refer to as the Kernel).
The Firmware Kernel is distributed as a .bin
file which is loaded to the Target through the
EMBEDDED PLC Utility. The Kernel runs the
PLC application in a loop (reading inputs →
evaluate the logic → updating outputs) and
also provides the communication interface
between the Target and the Workbench.
The ISaGRAF Workbench : The Workbench
provides a complete PLC programming
environment, including an editor for each of
the PLC programming languages,
downloading PLC application to the target,
simulation, program-debugging tools and
on-line monitoring of the PLC application.
1.2 BL2500 OVERVIEW
The BL2500 is an advanced Single Board Computer that incorporates flash memory, SRAM, digital I/O
ports, A/D converter input, D/A converter outputs, RS232/RS485 ports and Ethernet interface (10/100
Mbps). The BL2500 SBC gives PLC designers extremely low-cost embedded control for high-volume
applications such as product control, 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 via polarized locking industry standard Molex? type connectors enable rapid
assembly with wire harnesses. These connectors also provide dependable cable harness connectivity to
I/O.
Main features of the EMBEDDED PLC Firmware Kernel running on the BL2500 Target PLC, are shown in
Table 1.
