5.1.1 Data block 0
When using DB0, bear in mind that the data may only be evaluated in the
2nd PLC task (PLC_PRG2/ OB20). This is necessary because the data is upda-
ted in DB0 before the 2nd task is called and the NC evaluates the data after
execution. The error interface is an exception as it is synchronized by a strobe
(error counter) and an acknowledgement signal (error acknowledgement).

Data word Name Direction Type of signal
001 Error acknowledgement PLC ® NC static
This data word can be used by the PLC to recognize error messages and to
acknowledge error messages if the PLC has to evaluate an output error mes-
sage. If DW001 is unequal to DW133 (error counter), a new error message is
pending. Once the PLC has evaluated the error message, DW001 must be set
to the value of DW133. This way, the error in the NC computer is acknowled-
ged.
Data word Name Direction Type of signal
016.00 – 095.15 Error text NC ® PLC static
From DW016 onwards, the error text of the currently pending error is stored
as null−terminated string.
Data word Name Direction Type of signal
096.00 – 127.15 Additional error information NC ® PLC static
From DW096 onwards, additional information (e.g. axis letter) on the cur-
rently pending error is stored, if applicable, as a null−terminated string.
