Read request: Read out serial number of the Power Module (p7841[2])
To obtain the value of the indexed parameter p7841, you must 󹪝ll the telegram of the parameter
channel with the following data:
• PKE, Bit 12 … 15 (AK): = 6 (request parameter value (󹪝eld))
• PKE, Bit 0 … 10 (PNU): = 1841 (parameter number without o󹪜set)
Parameter number = PNU + o󹪜set (page index)
(7841 = 1841 + 6000)
• IND, bit 8 … 15 (subindex): = 2 (index of parameter)
• IND, bit 0 … 7 (page index): = 90 hex (o󹪜set 6000 corresponds to 90 hex)
• Because you want to read the parameter value, words 3 and 4 in the parameter channel for
requesting the parameter value are irrelevant. They should be assigned a value of 0, for
example.

Figure 8-16 Telegram for a read request from p7841[2]
Write request: Change restart mode (p1210)
The restart mode is inhibited in the factory setting (p1210 = 0). In order to activate the automatic
restart with "acknowledge all faults and restart for an ON command", p1210 must be set to 26:
• PKE, bit 12 … 15 (AK): = 7 (change parameter value (󹪝eld, word))
• PKE, bit 0 … 10 (PNU): = 4BA hex (1210 = 4BA hex, no o󹪜set, as 1210 < 1999)
• IND, bit 8 … 15 (subindex): = 0 hex (parameter is not indexed)
• IND, bit 0 … 7 (page index): = 0 hex (o󹪜set 0 corresponds to 0 hex)
• PWE1, bit 0 … 15: = 0 hex
• PWE2, Bit 0 … 15: = 1A hex (26 = 1A hex)

Figure 8-17 Telegram, to activate the automatic restart with p1210 = 26
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 (󹪝eld, word))
• PKE, bit 0 … 10 (PNU): = 348 hex (840 = 348 hex, no o󹪜set, as 840 < 1999)
