90 Application Note ET9300
Index Name Base Data Type Bit Size
0x000A OCTET_STRING ARRAY [0..n] OF BYTE 8*(n+1)
0x000B UNICODE_STRING ARRAY [0..n] OF UINT 16*(n+1)
0x0260 ARRAY_OF_INT ARRAY [0..n] OF INT 16*(n+1)
0x0261 ARRAY_OF_SINT ARRAY [0..n] OF SINT 8*(n+1)
0x0262 ARRAY_OF_DINT ARRAY [0..n] OF DINT 32*(n+1)
0x0263 ARRAY_OF_UDINT ARRAY [0..n] OF
UDINT 32*(n+1)
A padding entry is described with the notation ”pad_x” where x defines the bit size from 1 to 15.
13.4.6 Default/Min/Max
Default/Min/Max values shall be hexadecimal values. They shall have a leading “0x” and be of big
endian format.
13.4.7 M/O/C, B/S and rx/tx
The column “M/O/C” defines if an entry is mandatory optional or conditional. This value is only set in
the ESI file and has no influence to the slave application.
The column “B/S” specifies if an entry is a backup or setting object.
The column “rx/tx” specifies if an entry is rx or tx PDO map able.
13.4.8 Access
Defines the access rights via CoE. The access (read, write, readwrite) can be identical in PreOp,
SafeOp, Op. Or they can be different in some states. Example: A configuration value may be readable
and writeable in PreOp, but must not be changed any more in Op.
the allowed values are listed in Table 23: Entry access rights.
Table 23: Entry access rights
The state-dependent access rights shall be separated by a comma (,).
13.5 ENUM
Enums shall be defined in the index range 0x800 to 0xFFF (see also ETG.1000-6).
The used name and data type shall be “DTXXXXENYY”. XXXX is the index of the enumeration and
YY the used bit size.
