Fig. 7-1 Structure of the basic program
The PLC basic program is an integral component of the SINUMERIK 810D
tool box.
Set the “PLC memory” option if necessary.
There are two ways in which the completed PLC program can be loaded:
1. Load, test and edit the PLC program using SIMATIC STEP7 HiGraph (see
also Readme file on the basic program floppy).
2. Load an archived PLC program with PCIN or via MMC 101/102
