The Data Offset contains the info block size information. The software
expects the info block to consist of 70 bytes. So the first word of the
info block must have the value 70 (= 46h).
The Object Type word consists of four nibbles (1 nibble = 4 bits):
- lowest nibble: Object Version (must be 3)
- lower middle nibble: Type of Object (Curve = 0h)
- higher middle nibble: X dimension Code
- highest nibble: Y dimension Code

Table 7 Curve Info Block: Object Type
According to the definitions above the Object Type has the following
value:
- Position vs. Time curve: 0003h
- Cam profiles (Pos vs. Enc. Pos.): 0103h
Other object types are not supported yet.
The number of setpoints of the profile is given as 16bit value. The
minimal number of setpoints is 2.
This value defines the size of one setpoint. Position values are
defined in 32bit format (32bit = 4 bytes).
