4 Data Structures
4.1 Operating Modes
The GSD file contains 3 operating modes, supporting data I/O structures as follows:
Data structure Basic mode Extended mode Parameter upload/download mode
Soft Starter Control I/O Data Structure ✓ ✓ ✓
Soft Starter Monitoring I/O Data Structure ✗ ✓ ✓
Soft Starter Programming I/O Data Structure ✗ ✗ ✓
The basic mode allows starting and stopping the soft starter and reading limited information on operating status.
The extended mode defines more bytes allowing to read soft starter operating data such as actual motor current and motor
temperature.
The parameter upload/download mode allows reading and writing soft starter parameter values.
