Example
Read request: read out serial number of the Power Module (p7841[2])
To obtain the value of the indexed parameter p7841, you must fill the telegram of the
parameter channel with the following data:
• PKE, Bit 12 ... 15 (AK): = 6 (request parameter value (field))
• PKE, Bit 0 ... 10 (PNU): = 1841 (parameter number without offset)
Parameter number = PNU + offset (page index)
(7841 = 1841 + 6000)
• IND, bit 8 ... 15 (subindex): = 2 (index of parameter)
• IND, bit 0 ... 7 (page index): = 90 hex (offset 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.
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 (field, word))
• PKE, bit 0 ... 10 (PNU): = 4BA hex (1210 = 4BA hex, no offset, as 1210 < 1999)
• IND, bit 8 ... 15 (subindex): = 0 hex (parameter is not indexed)
• IND, bit 0 ... 7 (page index): = 0 hex (offset 0 corresponds to 0 hex)
• PWE1, bit 0 ... 15: = 0 hex
• PWE2, Bit 0 ... 15: = 1A hex (26 = 1A hex)
