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)
● IND, bit 8 ... 15 (subindex): = 2 (Index of the parameter)
● IND, bit 0 ... 7 (page index): = 90 hex (offset 6000 ≙ 90 hex)
● Because you want to read the parameter value, words 3 and 4 in the parameter channel
