288 Additional parameter data
Fieldbus addresses
Refer to the User’s Manual of the fieldbus adapter.
Pointer parameter format in fieldbus communication
Value and bit pointer parameters are transferred between the fieldbus adapter and
drive as 32-bit integer values.

32-bit integer value pointers
When a value pointer parameter is connected to the value of another parameter, the
format is as follows:
For example, the value that should be written into parameter 33.02 Superv1 act to
change its value to 01.07 Dc-voltage is
0100 0000 0000 0000 0000 0001 0000 0111 = 1073742087 (32-bit integer).
When a value pointer parameter is connected to an application program, the format is
as follows:
Note: Value pointer parameters connected to an application program are read-only
via fieldbus.
Type Data type. See enum, INT32, Bit pointer, Val pointer, Pb, REAL, REAL24,
