Originator
Originator (control system)
Type 1: A device capable of configuring target devices (targets) and simultaneously
connect to the targets.
Type 2: A device not capable of configuring target devices (targets). Safety-related
parameters, SNN and SCID are configured using an SNCT tool.
Passivation
In a safety-related peripheral equipment with outputs, the safety controller does not
transmit the output values provided by the safety program in the process image to the
fail-safe outputs in the event of a passivation but sends substitute values (e.g. 0)
instead.
Port
Connection
Address part that assigns data segments to a network protocol.
Router Network component for coupling several subnets.
SCCRC
Safety Configuration CRC
CRC that checks the Safety Open device configuration data.
SCID
Safety Configuration Identifier
SCCRC and SCTS combination used to uniquely identify a target and originator
configuration.
SCTS
Safety Configuration Time Stamp
Time/date stamp, identifies the time and date when a configuration was created or
changed.
SIL
Safety Integrity Level: Four discrete levels (SIL1 to SIL4). The higher the SIL of a
safety instrumented system, the lower the probability that the system cannot execute
the required safety functions.
