4.2.1. Check Position „C“ (43h)
This command provides the alignment status of target versus actual value. If the actual value is within the target
tolerance window, the response will be „o“ (6Fh) for OK together with the current profile number. If the actual
value is outside the tolerances, „x“ (78H) followed by the current profile number will be replied.
Example: (active profile number = 05)
SOH Adr Cmd EOT CRC
Transmission
01h 20h 43h 04h 0Ah
Response if actual value is within the tolerances:
SOH Adr Cmd Stat. Profile no.=05 EOT CRC
Response
01h 20h 43h 6Fh 30h 35h 04h A5h
Response in case of actual value is outside the tolerances:
SOH Adr Cmd Stat. Profile no.=05 EOT CRC
Response
01h 20h 43h 78h 30h 35h 04h 1D
4.2.2. Read actual value „R“ (52h)
This command is utilized to read the 5-digit actual value (bottom line of display). The amount of data 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 of less than 5 (4) digits will come with preceding zeroes.
Please note that N 150 provides a 5-digit actual value.
Example: Actual value = -32.50
SOH Adr Cmd EOT CRC
Transmission
01h 20h 52h 04h 40h
SOH Adr Cmd Actual value = –32.50 EOT CRC
Response
01h 20h 52h 2Dh 30h 33h 32h 35h 30h 04h 54h
4.2.3. 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
transmitted as 5-digit number (see example 3). Please consider that SPA targets comprise 5 digits only.
Example 1: Read active target (profile number = 12; target = 12.50)
SOH Adr Cmd EOT CRC
Transmission
01h 20h 53h 04h 2A
SOH Adr Cmd Profile no. = 12 Target = 12.50 EOT CRC
Response
01h 20h 53h 31h 32 30h 30h 31h 32h 35h 30h 04h 3E
Response upon clearing all targets:
SOH Adr Cmd Profile no. =
FFh
Target = FFFFFFh EOT CRC
Response
01h 20h 53h 3Fh 3F 3Fh 3Fh 3Fh 3Fh 3Fh 3Fh 04h 2Ah
Example 2: Read specific target (profile number = 17; target = 12.50)
SOH Adr Cmd Profile no. = 17 EOT CRC
Transmission
01h 20h 53h 31h 37h 04h 16h
SOH Adr Cmd Profile no. = 17 Target = 12.50 EOT CRC
Response
01h 20h 53h 31h 37h 30h 30h 31h 32h 35h 30h 04h BCh
Example 3: Write specific target (profile number = 17; target = -12.50)
