■Functions Used
●Smart FB Library (Only CP1L)
Smart FB Library (smart function block library) is a set of components provided by
OMRON as an FB (function block). By using Smart FB Library, OMRON PLC and
FA component functions can be easily used in PLC programs.
When using serial ports for communication between an inverter and a PLC, substantial
knowledge of communication command specifications and communication procedures
are generally required in creating the program. In such cases, Smart FB Library can be
used to significantly simplify the programming process.
Smart FB Library for V1000/A1000 Inverter
*FB used in this example.
Note Documentation (PDF file) on Smart FB Library functions can be found in the
[FBL] - [omronlib] - [Inverter] - [INVRT] - [Serial] folder. For details on the Smart FB
Library, refer to this file.
