Note:
Not all C functions and C function blocks are available for simulation. Section 5.2.2 and 5.2.3
describes C functions and C function blocks that are specific to the BL2500 and are not available for
simulation.
5.2 ISAGRAF SOFTWARE REFERENCE
This section presents information about the specific elements of the ISaGRAF Workbench Library for the
EMBEDDED
PLC BL2500 (I/O boards, C functions and C function blocks).
5.2.1 I/O Boards
ISaGRAF I/O board library for the BL2500 is included as part of the BL2500 BSP to make it easy to
communicate with the BL2500 supported inputs and outputs. These I/O boards are described in the
following sub-sections.
