4.2.5. Read / write parameter offset, command „U“ (55h)
This command is to read or write the offset that is added to the true current value. First however the function
must be enabled in command bit parameter ‚a’ (61h).
Example 1: Read offset
SOH Adr Cmd EOT CRC
Transmission
01h 20h 55h 04h 26h
Example 2: Write offset
SOH Adr Cmd data (offset = –20,00) EOT CRC
Transmission
01h 20h 55h
2Dh 30h 32h 30h 30h 30h
04h C3h
Response in both examples:
SOH Adr Cmd data (offset = –20,00) EOT CRC

4.2.6. Read / write parameter profile number, command „V“ (56h)
This command is to readout the number of the presently active profile respectively for altering the profile.
Example 1: Read active profile (active profile number = 38)
SOH Adr Cmd EOT CRC
Transmission
01h 20h 56h 04h 20h
SOH Adr Cmd Profile no. = 38 EOT CRC
Response
01h 20h 56h
33h 38h
04h 28h
Response after reset upon deletion of all profiles:
SOH Adr Cmd Profile no. = FF EOT CRC
Response
01h 20h 56h
3Fh 3Fh
04h 16h
Example 2: Transmit new profile (new profile number = 17)
SOH Adr Cmd Profile no. = 17 EOT CRC
Transmission
01h 20h 56h
31h 37h
04h 3E
SOH Adr Cmd Profile no. = 17 EOT CRC
Response
01h 20h 56h
31h 37h
04h 3E
Example 3: Transmit new profile by broadcast command to all N 141 (Identifier = 99 (83h); new profile no. =
17)
SOH Adr Cmd Profile no. = 17 EOT CRC
Transmission
01h 83h 56h
31h 37h
04h 04
Response Not confirmed
To verify whether the new profile has been accepted by all N141 utilize check command „C“ (43h).
