4.2.4. Read actual value „R“ (52h)
This command is for reading the 5-digit actual value (bottom display). Data amount is always 6 bytes. In case of
a negative value, the minus sign (2Dh) together with 5 data bytes is replied. Positive values are represented by
6 data bytes without sign. Values inferior to 5(4) digits will come with preceding zeroes. Please note that N 153
provides a 5-digit actual value.
Example: Actual value = -32.50

4.2.5. Read / write target (profile) „S“ (53h)
This command is utilized to read the presently active target (profile value) respectively to read or write a specific
target. Data are composed by profile number (2 bytes) and target (6 bytes). Note: Negative targets are transmit-
ted as 5-digit number (see example 3). Please consider that SPA targets comprise 5 digits only.

Note: Instead of command „S“ also command „SP“ may be utilized. The function is fully identical to command
“S”. In case command SD is utilized it might be easier to apply command SP due to their identical protocol
length. Please consider that with anterior or other multicon devices command „SP“ maybe is not available.
