1.3 ABOUT THIS MANUAL

This manual provides instructions for installing, testing, configuring and interconnecting the Z-World SBC
BL2500 running the
EMBEDDED
ISaGRAF Workbench.
This User's Manual is divided into the following chapters:
•
This chapter provides and overview of the
as conventions used and reference documents.
•
Chapter 2, Getting Started: Explains how to install the different
sample application.
•
Chapter 3, Running Sample Applications: Provides instructions how to run the different types of
sample applications and also how to create a PLC application using the ISaGRAF Workbench.
•
Chapter 4, Hardware Reference: Provides a detailed description of the I/Os and communication ports
present in the SBC BL2500 and how to configure them in order to work with

BL2500 with Rabbit core module RCM3200 (10/100BaseT, 512K Flash, 256K +
512K SRAM, 44.2 MHz clock speed). Z-World P/N: 101-0602
- 16 Digital Inputs
- 8 Digital Outputs
- 1 Analog Input (connected through AD0): 10 bits resolution, 0 – 3.3 V
- 1 Analog Output (connected through DA1): 10 bits resolution, 0 – 3.3 V
Modbus RTU over TCP/IP using static IP address
Modbus RTU over RS232 (using serial port E) or RS485 (using serial port D):
- Baud rate: 19200, 9600, 4800, 2400, 1200 or 600 (configurable through
PLC Utility)
EMBEDDED
- Parity: None
- Data bits: 8
- Stop bits: 1
- Flow Control: None
Minimum polling period time is 1 cycle duration for Modbus TCP and 2 x cycle
duration for Modbus RTU over RS232/RS485. Cycle duration corresponds to the
time that kernel executes one cycle (read inputs → execute logic → update
outputs)
- Digital Input scan time is approx. 200 µs.
- Analog Input scan time is approx. 83 ms.
- Digital Output update time is approx. 30 µs per output.
- Analog Output update time is approx. 120 µs.
- Boolean instruction execution time is approx. 30 µs.
- Program execution overhead is approx. 100 µs per program.
Maximum size of ISaGRAF application database is 50000 bytes.
Size of ISaGRAF real-time database (holds variables, SFC engine data, C function
and function blocks data) is 10000 bytes.
Free root memory on the BL2500 is approx. 9000 bytes.
PLC firmware kernel total code size is approx. 260000 bytes.
