Extend Telegrams And Change Signal Interconnection - Siemens SINAMICS G120 Operating Instructions Manual

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 fill 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 = index1)
● IND, bit 0 ... 7 (page index): = 0 hex (offset 0 ≙ 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))

Extend telegrams and change signal interconnection

When you have selected a telegram, the inverter interconnects the corresponding signals
with the fieldbus interface. Generally, these interconnections are protected so that they
cannot be changed. With the appropriate inverter settings, these interconnections can be
changed.
Extend telegram
Every telegram can be extended, by "attaching" additional signals.
Procedure
Proceed as follows to extend a telegram:
1. Using STARTER or an operator panel, set parameter p0922 = 999.
2. Set parameter p2079 to the appropriate value of the corresponding telegram.
3. Interconnect additional PZD send words and PZD receive words with signals of your
choice via parameters r2050 and p2051.
You have extended the telegram.
