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)

Beispiel 2: Read target of a specific profile (profile number = 17; target = 12,50)
SOH Adr Cmd Profile =17 EOT CRC
Transmission
01h 20h 53h 31h 37h 04h 16h
SOH Adr Cmd Profile =17 target = 12,50 EOT CRC

Example 3: Set target in a specific profile (profile number = 17; target = -12.50)
SOH Adr Cmd Profile =17 target = -12,50 EOT CRC
Transmission
01h 20h 53h 31h 37h 2Dh 30h 31h 32h 35h 30h 04h FBh
SOH Adr Cmd Profile =17 target = -12,50 EOT CRC
Response
01h 20h 53h 31h 37h 2Dh 30h 31h 32h 35h 30h 04h FBh
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.
Example 4: As example 3, but using command „SP“
