#IDENT RD [ AX <axis_ name> | AXNR <expr> ID <i dent_nr> P = <v ariable> TYP <expr> DEC <expr> <drive_type>]
AX<axis_name> Name of the SERCOS axis
AXNR<expr> Logical axis number of the SERCOS axis, positive integer
ID<ident_nr> Identification number in SERCOS format, e.g. S-0-0047 or P-0-0129
<variable> Variable to which the value to read is to be saved.
e.g. P-parameter or V.P. , V.L. or V.S. variables.
TYP<expr> Data type of the value (2 or 4 byte length):
Valid values | Significance |
|---|---|
2 | 2 bytes data length |
4 | 4 bytes data length |
DEC<expr> Number of places after the decimal point; positive integer
<drive_type> Drive type
Valid IDs | Significance |
|---|---|
SERC | Sercos drive (currently only drive permitted) |
Programming example
:
#IDENT RD [AX X ID S-0-0104 P=P1 TYP 4 DEC 2 SERC] or
#IDENT RD [AXNR 1 ID S-0-0104 P=V.P.KV_WERT TYP 4 DEC 2 SERC]

No plausibility check as regards the logical axis number, the identification number and the programmed attributes data type and places after decimal point is conducted. The operator is solely responsible for making the correct entries. |
