I've created a library object where blocks are in FB and FC. From that library, I want to use some of the blocks in CFC. But I'm not able to get that. *Is there any way of implementing S7 Library in CFC?* In CFC I'm not getting the Library nor the S7 Program element. FYI I've attached the zip file. Thanx and Regards Attachment CFC.zip (158 Downloads)

Here each FB consist of one or several standard FBs and compiled into user FB using CFC compiler. This is described in the CFC online help under the topic "Creating block types".

Thanx and Regards Hello, You can use the CFC with a S7-CPU and with a FM458, by generating a chart container for the module _(S7-CPU or FM458). But both "target systems" will use there own libaries. For S7-CPU you will find only a few blocks for a FM458 you will find about 300 FBs. As far as I know it is possible to gererate own FBs for a S7-CPU and import them in CFC, but I never made it. For the FB458 you can generate own FBs by combinating the standard FBs. This is called "Plan in Plan" or"new FB out of FB charts" (this is the translation of the german name, I don't know theenglish name for it.)People who used STRUC call them "macros". With the FB generator (not included in D7-SYS, extra product) you can write FBs in (ANSI) C.
