Write request: Assign digital input 2 with the function ON/OFF1 (p0840[1] = 722.2)
In order to link digital input 2 with ON/OFF1, you must assign parameter p0840[1] (source,
ON/OFF1) the value 722.2 (DI 2). To do this, you must populate the telegram of the
parameter channel as follows:
● PKE, bit 12 ... 15 (AK): = 7 hex (change parameter value (field, word))
● PKE, bit 0 ... 10 (PNU): = 348 hex (840 = 348 hex, no offset, as 840 < 1999)
● IND, bit 8 ... 15 (subindex): = 1 hex (CDS1 = Index 1)
● IND, bit 0 ... 7 (page index): = 0 hex (offset 0 corresponds to 0 hex)
● PWE1, Bit 0 ... 15: = 2D2 hex (722 = 2D2 hex)
● PWE2, Bit 10 ... 15: = 3F hex (drive object - for SINAMICS G120, always 63 = 3f hex)
● PWE2, Bit 0 ... 9: = 2 hex (Index of Parameter (DI 2 = 2))
