4.2.1. Check Position, command „C“ (43h)
This command provides the alignment status of target versus current value. If the current value is within the
target tolerance window, the response will be „o“ (6Fh) for OK together with the current profile number. If the
current 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 current value within the tolerance window:
SOH Adr Cmd Status Profile no. = 05 EOT CRC
Response
01h 20h 43h
6Fh 30h 35h
04h A5h
Response if current value outside the tolerance window:
SOH Adr Cmd Status Profile no. = 05 EOT CRC
Response
01h 20h 43h
78h 30h 35h
04h 1D
Extended command Check Position „CX“
The command extension „Check Position CX “provides besides the alignment status target versus current value
also the contents of the status and error register as well as the current value. The profile number is not
transmitted.
Note: SPA N 141 does not provide any status or error register. For reasons of compatibility to other multicon
equipment here the permanent parameter 80h is transmitted, i.e. the 4 data bytes have no significance.
Example:
SOH Adr Cmd
SCmd
EOT CRC
Transmission
01h 20h 43h 58h 04h A8h
SOH Adr Cmd Stat. Status-Reg Error-Reg Current value = -12,50 EOT CRC
Response

04h B7h
4.2.2. Read parameter current value, command „R“ (52h)
This command is for readout the 6-digit current value (bottom line). The amount of data is always 6 bytes. In
case of a negative value, the “-“ sign (2Dh) together with 5 data bytes is replied. Positive values come as 6 data
bytes without sign. Values of less than 6 (5) digits will come with preceding zeroes.
Example: Current value = -32,50
SOH Adr Cmd EOT CRC
Transmission
01h 20h 52h 04h 40h
SOH Adr Cmd Current value = –32,50 EOT CRC
Response
