Safety I/O
Safety inputs
The DST1-ID12SL-1 supports 12 safety inputs.
The DST1-MD16SL-1 supports 8 safety inputs.
The DST1-MRD08SL-1 supports 4 safety inputs.

Functions
SECTION 5
DST1 Series
Specifica-
tions
Input circuit diagnosis
Diagnoses internal circuits and external devices and wiring using test
pulses.
Input delays (ON or
OFF)
The input time constant can be set from 0 to 126 ms in units of 6 ms. This
function can be used to reduce the effects of chattering and external
noise.
Dual channel evalua-
tion
Dual channel evaluation can be used to evaluate the discrepancy time
between two associated local input data items or input signals.
Test outputs
Four independent test outputs are supported. Test outputs are used in
combination with safety inputs. Depending on the settings, they can also
be used as signal output terminals.

Functions
SECTION 5
DST1 Series
Specifica-
tions
Broken wire detection
(terminal T3 only)
Broken wires can be detected for terminal T3.
Overcurrent detection
and protection
When an overcurrent is detected, the output is turned OFF to protect the
circuit.
Safety outputs
The DST1-MD16SL-1 supports 8 safety outputs.
The DST1-MRD08SL-1 supports 4 safety outputs.
The DST1-XD0808SL-1 supports 8 safety outputs.

tion of Safety
Functions
SECTION 5
DST1 Series
Specifica-
tions
Output circuit diagnosis
(See note.)
Diagnoses internal circuits and external devices and wiring according to
test pulses.
Overcurrent detection
and protection (See
note.)
When an overcurrent is detected, the output is turned OFF to protect the
circuit.
Dual channel evalua-
tion
When an error occurs at one of two associated local outputs, the dual
channel evaluation sets the two outputs to the safe state without relying on
a user program.
DeviceNet Communications
Safety Slaves
DST1-series Terminals can be operated as DeviceNet Safety Slaves. Not
only specified I/O areas, but also internal status information can be
assigned in Safety Masters.
Standard Slaves
DST1-series Terminals can be operated as Standard Slaves. Not only
specified I/O areas, but also internal status information can be assigned in
Standard Masters.
Explicit message commu-
nications
Internal status information can be read by using a service for explicit mes-
sages.

Explicit Mes-
sages
Automatic baud rate detec-
tion
The baud rate is automatically set to the baud rate of the network.
-
System Startup and Error Recovery Support
Error history
Internally saves information on errors that are detected.
Online monitoring
Internal status information and I/O data can be read using the Network
Configurator.
