7.1 General Notes on FCs / FBs
Block Library
The functions (FCs) and function blocks (FBs) described here are supplied with the
STEP 7 basic package unless indicated otherwise.
The following list shows the numbers of the FCs as they are supplied with the
configuration tool. You can change these numbers.
Under SIMATIC_NET_CP, you can also see which folders contain blocks after
installing the NCM S7 for Industrial Ethernet option (default setting in STEP 7
Setup). Please note that you must use different FCs for the S7-300 and S7-400
(separate libraries).
