The DST1-series Safety I/O Terminals support the DeviceNet Safety protocol
and provide various functions for the Safety System. The DST1-series Safety
I/O Terminals allow the user to construct a safety control/network system that
meets the requirements for Safety Integrity Level (SIL) 3 according to IEC
61508 (Functional Safety of Electrical/Electronic/ Programmable Electronic
Safety-related Systems) and the requirements for Safety Category 4 accord-
ing to EN 954-1.
The DST1-series Safety I/O Terminal's safety I/O data is transmitted through
safety I/O communications conforming to the DeviceNet Safety Protocol, and
the data processing is performed in conducted in the Safety Network Control-
ler (NE1A-SCPU01).
Also, the status of the safety I/O data can be monitored in a standard PLC in
an existing DeviceNet network using standard I/O communications or explicit
message communications.
The DST1-XD0808SL-1 Logic Terminal has built-in logic functions. This
enables direct control of local outputs from local inputs, allowing reaction time
to be shortened.
