Call example
As far as the time is concerned, the basic program must be executed before the user
program. It is, therefore, called first in OB 1.
The following example contains the standard declarations for OB 1 and the calls for the basic
program (FC2), the transfer of the MCP signals (FC19), and the acquisition of error and
operating messages (FC10).
