6.12.1 Description
Library
A library contains one or more function blocks. In order to be able to use a library’s
function blocks, the library must first have been integrated into the project. Only
one library may be integrated into a project. The maximum size of a library for the
PS program amounts to 16K WORD, for the PN program to 32K WORD.
Function block
Function blocks (FB) are program sections which, like a subprogram, can be called
up by the user program. They offer the possibility of first using created program
sections in any user programs. An FB must possess at least one input and one
output. An FB is created by means of the ladder diagram programming language in
the same way as the user program.
