1) D = Default with DX 0 not loaded or block missing
2) xx = field length (number of data words occupied by the parameters)
3) For updating timers, please read the explanation on the following page
4) For parameters and their significance, see the table on page 7-12.
Note
The current PG software (STEP 5/ST Vers. 6 or STEP 5/MT
Vers. 2) for generating DX 0 using a screen form does not transfer
the parameters for interface error handling (2000 or 2001) and for the
selection
"Warm restart or retentive cold restart"
(4000 or 4001).
You can enter these parameters e.g. with the "output block" PG
function (do not forget to change the block length). You can no
longer edit a DX 0 modified in this way using the output screen form
of the current PG software.
