4.2.4. Read current value „R“ (52h)
This command reads the 6-digit current value (lower line of display). Data length is always 6 bytes. In case of a
negative value, the negative sign (2Dh) will be returned together with 5 data bytes. Positive values come in 6
data bytes without sign. Values inferior to 6 (5) digits will come with leading zeroes.
Example: current value = -32.50

4.2.5. Read / write target (profile) „S“ (53h)
This command reads the presently active target, sets a specific target respectively reads out latter. Data com-
prise profile number (2 bytes) and target (6 bytes). Important: Negative targets come as a 5 digit number (see
example no. 3)
Example 1: read target of the current profile (current profile number = 12; target = 12.50)

Note: Instead of command „S“ you may also use command „SP“. Functionality is fully identical to command
„S“. Due to the equal length of protocol it might be easier using SP in conjunction with command SD.
