5.2.6 Functions
Functions are executed by calling them from parent, child, or grandchild drawings using the FSTART
command.
Functions can be called from any drawing, and the same function can be called at the same time from
different types of drawings and from different levels of drawings. Another completed functions can
also be called from functions.
Using functions has the following advantages.
• Easier creation of user program components
• Easier writing and maintenance of user programs
Functions include standard system functions that are already in the system and user functions that are
defined by the user.
( 1 ) Standard System Functions
The transmission and other functions listed below are already created as standard system functions.
Standard system functions cannot be changed by users.
( 2 ) User Functions
The functions (programs) and the function definitions can be changed (programmed) freely by users.
The maximum number of user functions that can be defined is 500 drawings.
