S-DIAS Safety SSI Absolute Value Encoder SSI 021
The S-DIAS Safety SSI absolute value encoder module SSI 021 provides
the values of two absolute value encoders to the Safety CPU as well as the
non-Safe CPU (standard PLC). Since hardware version 2.0 rotary encoders
are supported.
The 2-channel Safety function is implemented by processing the position
values in the so-called Safety core (two micro controllers with cross
communication).
The connection to the Safety CPU (SCP 011 / SCP 111) is made via the
internal Safety but, which is completely independent of the S-DIAS bus.
The components supply the Safety CPU values, such as position, speed
and absolute value limit violation. For a detailed listing of the function and
settable parameters, see the module description in the SafetyDesigner.
The SSI 021 parameters are set via the program in the default PLC (bit
length of the SSI signal, SSI frequency, ...) and therewith, participants in
the S-DIAS bus of the standard PLC as well as on the internal Safety bus
of the Safety CPU. Stand-alone mode with a Safety CPU (without standard
PLC) is therefore not possible.
The safety-related component of the module meets the requirements for SIL3 in accordance
with EN IEC 62061 and PL e, cat. 4 in accordance with EN ISO 13849 (with two-channel
use).
