Input links are required across terminals DI2, +24V and DI3, +24V if the Digistart IS soft starter is being operated in Remote mode. In
Local mode, links are not required.
Digistart IS Pr 3O Comms in Remote selects whether the soft starter will accept Start, Stop or Reset commands from the
NOTE
Serial Network Master while in Remote mode. See the Digistart IS User Manual for parameter details.

If communication fails between the module and the network, the Bus Status LED will go off. When communication is
NOTE
restored, the Bus Status LED will come back on.
When a communications failure occurs, the soft starter may trip if the Communication Timeout parameter for the network is
NOTE
set greater than zero. When communication is restored, the soft starter must be reset.

Master Configuration

4.1

Master setup

Import the file "SSPM08A8.gsd" into your Master configuration tool. This file is available on the supplied CD or can be downloaded from
the website www.controltechniques.com
If your Master uses on-screen icons, two graphic bitmap files are available from the CD or can be downloaded from the
website www.controltechniques.com
The Profibus Module has a slave address range of 0 to 99.
NOTE
If the Profibus network fails, the module will leave data exchange mode after the network watchdog timeout period has expired. This
timeout period is set at the Master configuration tool.
A Communication Timeout parameter in the GSD file sets how soon after this event the soft starter will be forced into a trip state.
The user can adjust the Communication Timeout parameter in the GSD file to any setting between 0 and 100 seconds. The default
setting is 10 seconds.
If the Communication Timeout parameter is set to 0, the current state of the soft starter will remain unchanged on a network
NOTE
failure. This gives the user the option of operating the soft starter via local control, but is NOT failsafe.
4.2

Operating modules

The GSD file contains three operating modules, supporting data I/O structures as follows:
Table 4-1 Data structures
Data Structure
Soft Starter Control I/O on page 7
Soft Starter Monitoring I/O on page 8
Soft Starter Programming I/O on page 10
The Basic Module allows the user to start and stop the soft starter and read limited information on operating status.
The Extended Module defines additional bytes allowing the user to read soft starter operating data such as actual motor current and
motor temperature.
The Parameter Upload/Download Module allows the user to read and write soft starter parameter values (only applicable to Digistart IS
soft starters).
