3.10 Using libraries
Introduction
As with standard blocks, you have the option of storing F-blocks which you wish to reuse as
master copy or types in global libraries or in the project library.
Additional information can be found in the help for STEP 7 under "Using libraries".
Reusing F-blocks which have already been tested and accepted
Please note the following when reusing F-blocks which have already been tested and if
applicable also accepted:
● Document the signature and start value signature of the F-block after you have compiled,
tested and possibly accepted the F-block.
● Document the version set for "Instructions (without their own version)" in the Safety
Administration Editor under "Settings"/"System library elements used in safety program".
For documentation purposes, you can create a safety summary of the safety program you
used to create the F-block.
● When re-using the F-block, carefully ensure that the signature and start value signature of
the F-block have not been changed.
For F-blocks with instructions for which a version is indicated in the "Version" column of the
"Instructions" task card, you must also note the following:
● Document the versions of these instructions that were set at the time the F-block was
compiled and on the basis of which the F-block was tested and, if applicable, approved.
You can use the safety summary for documentation purposes.
● When using the F-block again make sure that the documented versions are set for these
instructions in the "Instructions" task card.
● If versions other than the documented versions are set for these instructions, you must
check yourself whether the F-block still works with these versions as intended.
To do so, identify any differences between the versions based on the online help on the
instructions.
You need to have the F-block retested and accepted. Additional information on the
instruction versions can be found in the help for STEP 7 under "Fundamentals for instruction
versions".
To help you manage F-blocks that you wish to reuse and that have already been tested and if
applicable accepted, we recommend that you save these blocks as types in a global library.
