Appendix 9.1.4 Development tool
GX Works2 (Simple project) ver 1.12N or later is required to develop sequence
programs using FBs.
POINT
Depending on the FB library, supporting versions of GX Works2 may differ.
For details, refer to the download page of each FB.
Appendix 9.1.5 FB specifications and precautions
The following specifications and precautions must be understood prior to using FBs.
1. An FB cannot be used in another FB.
2. Because an FB specific process is added when an FB is arranged, the
number of steps increases when compared to a ladder created without an FB.
3. FBs cannot be used in an interruption program.
4. FBs whose execution does not complete within a scan cannot be used in the
FOR to NEXT instruction loops or subroutine programs.
