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
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)
s
SOH Adr Cmd Profile no. = 17 Target = -12.50 EOT CRC
Transmission
01h 20h 53h 31h 37h 2Dh 30h 31h 32h 35h 30h 04h FBh
SOH Adr Cmd Profile no. = 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“ also command „SP“ may be utilized. The function is fully identical to command
“S”. If 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.
Example 4: As in example 3 but utilizing command „SP“
SOH Adr Cmd Sub Profile no.=17 Target = -12.50 EOT CRC
Transmission
01h 20h 53h 50h 31h 37h 2Dh 30h 31h 32h 35h 30h 04h 29h
SOH Adr Cmd Sub Profile no.=17 Target = -12.50 EOT CRC
Response
01h 20h 53h 50h 31h 37h 2Dh 30h 31h 32h 35h 30h 04h 29h
Direct positioning „SD“
This command may be utilized for direct positioning operations. Only the target less any profile number is
transmitted to SPA. The profile number after the command “S” is replaced by sub command “D” ( = dimension).
Motor start enable requires transmitting in addition motor start command “D”.
Example 4: Write position value for direct positioning operation (less profile)
SOH Adr Cmd Sub Position value = 278.25 EOT CRC
Transmission
01h 20h 53h 44h 30h 32h 37h 38h 32h 35h 04h 6Bh
SOH Adr Cmd Sub Position value = 278.25 EOT CRC
Response
01h 20h 53h 44h 30h 32h 37h 38h 32h 35h 04h 6Bh
Note: The position value is saved in the non-volatile memory and will be retained in case of power failure. In this
case the previously selected profile is utilized again.
