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.
Master > Slave output bytes are structured as follows.
Table 5-7 Programming output byte structure

Slave > Master input bytes are structured as follows.

Parameter access level is defined as follows:
0 = Read only
1 = Operator (Digistart IS parameter groups 1 to 14)
2 = Supervisor (Digistart IS parameter groups 15 and 16)
This operating module only functions with Digistart IS soft starters.

Profibus Diagnostics and Modes

6.1

Profibus diagnostic telegram and flag

The Profibus Module supports external diagnostics. The following telegram will be sent to the Master if the soft starter trips or if a
parameter is changed at the soft starter.

Byte 0 User diagnostic length (Always set = 3)
Byte 1 Trip code
Byte 2
Changed parameter number (Digistart IS only)
6.1.1 Trip code
When the soft starter trips, a diagnostic flag is set at the Master and the trip code is reported in Byte 1. When the soft starter is reset, the
diagnostic flag and trip code data are reset = 0, provided the trip condition does not still exist (see Soft Starter Monitoring I/O Data
Structure on page 8 for trip codes).
6.1.2 Changed parameter number
If a parameter is changed via the keypad, the affected parameter number is reported in Byte 2. When the Master reads or writes the
changed parameter, Byte 2 is reset = 0.
A changed parameter number does not set a diagnostic flag.
