5.11.6 SSI encoder evaluation
The decentralised controllers 8400 protec HighLine and 8400 protec EMS are provided with a
synchronous serial interface (SSI) for evaluating SSI encoders. All SSI encoders that use the
Stegmann SSI protocol are supported.
• Supported bit rates for SSI communication: 100 ... 1000 kbps
• Supported data word widths: 1 ... 31 bits (effective)
• Supported output code of the SSI encoder: Gray or binary
• The SSI encoder can be used as position encoder or master encoder with a minimum cycle time
of 1 ms.
• The received SSI data words are made available to the application via the LS_MultiEncoder
system block for being further processed in the function block editor. They can also be fed
automatically into the control loop with a corresponding parameterisation.
Parameterisation dialog in the »Engineer«
When pressing the SSI configuration... button in the encoder/feedback system dialog box, you get to
the parameterisation dialog for configuring the SSI encoder:

The technical data of the synchronous serial interfaces (SSI) can be found in the 8400
hardware manual.
• The hardware manual has been stored in electronic form on the data carrier supplied
with the 8400 drive controller.
