Default value:
Because a SINUMERIK 840C is always equipped with a PLC (135 WB), bit 0 of MD 5038 must
always be set to 1 and bits 1 to 7 to 0. With 1 in bit 0 of MD 5039, the control indicates that
the PLC has been recognized.

The dynamic limit switch for ELG following axes can be operated without
dead-time compensation in certain cases. Not the actual value but the
precalculated "actual value" is used for calculation. The function is activated
via MD 5029.0 and axis-specifically via MD 584*.1.
