6.3 Soft Starter Programming I/O Data Structure
The Soft Starter Programming I/O Data Structure allows the user to upload (read) and
download (write) soft starter parameter values over the network.
CAUTION
Do not change the default values of the Advanced parameters (parameter group
20). Changing these values may cause unpredictable behaviour in the soft starter.
Outputs
Master > Slave output bytes are structured as follows.
Byte
