3.6.4.2 Assignment of user data areas P0 ... P4
Data type in P0 / byte 3
Parameter value in P3 and P4
Depending on the data type, the parameter value assigns 1 ... 8 bytes. The data is stored in the Little-
Endian format, i.e. first the low byte or low word, then the high byte or high word:
Range Byte 1 Byte 2 Byte 3 Byte 4
P0 Status/error code Data type Reserved
P1 Index Reserved Reserved
P2 Subindex Reserved Reserved*
P3 Parameter value
P4 Parameter value
* When the data type VISIBLE_STRING is transmitted, byte 4 contains the number of the characters attached.
ID Data type Data length
0x01 INTEGER_8 1 byte
0x02 INTEGER_16 2 bytes
0x03 INTEGER_32 4 bytes
0x04 INTEGER_64 8 bytes
0x05 UNSIGNED_8 1 byte
0x06 UNSIGNED_16 2 bytes
0x07 UNSIGNED_32 4 bytes
0x08 UNSIGNED_64 8 bytes
0x09 FLOATING_POINT 4 bytes
0x0A VISIBLE_STRING max. 256 bytes
0x0B OCTET_STRING max. 256 bytes
