devices do Not turn ON when the safety output line is grounded.

For the DST1-MRD08SL-1, isolating transformers, such as TR1, that are used to
isolate between overvoltage categories III and II must conform to IEC60742, and
the insulation between the primary input and secondary output must satisfy at
least the basic insulation standards of overvoltage category III. One side of the
secondary output of the isolating transformer must be grounded to prevent
electrical shock in case of short-circuiting to the ground or to the frame of the
isolating transformer. To protect the isolating transformer and to prevent electri­cal shock in case of short-circuiting to the frame, insert fuses according to

1-1-1 About the DST1-series Safety I/O Terminals

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 accord­ing 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 Control­ler (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.

1-4-1 DST1-series Safety I/O Terminals

Safe State

The following status is treated as the safe state by the DST1-series Safety I/O
Terminals.

• Safety outputs: OFF

• Output data to network: OFF

Therefore, the DST1-series Safety I/O Terminals must be used for applica­tions in which it enters into safe state when the safety outputs turn OFF and
the output data to the network turns OFF.

Self-diagnosis Functions

Self-diagnosis is performed when the power is turned ON and periodically
during operation. If an error occurs, it will be treated as a fatal error (the MS
indicator will light in red), and the safety outputs and output data to the net­work will turn OFF.

Access Control by Password

After configuration data had been downloaded and verified, the configuration
data within the DST1-series Safety I/O Terminals can be protected by a pass­word.

Safety Inputs with Test Pulses (Input Circuit Diagnosis)

A test output is used in combination with a safety input. Specify the corre­sponding test output terminal to use as the test source. The test output termi­nal is used as a power supply to connect an external input device to the safety
input terminal.

A test pulse is output from the test output terminal to diagnose the internal cir­cuit when the external input contact turns ON. Using this function, short-cir­cuits between input signal lines and the power supply (positive side), and
short-circuits between input signal lines can be detected.

Setting Dual Channel Mode and Discrepancy Time

The consistency between signals on two channels can be evaluated. Either of
the following settings can be selected. This function monitors the time during
which there is a discrepancy in the logic between the two channels set as dual
channels. If the length of the discrepancy exceeds the set discrepancy time (0
to 65,530 ms, in increments of 10 ms), the safety input data and the individual
safety input status will turn OFF for both inputs.

IMPORTANT The dual channel function is used with 2 consecutive inputs that start from

even input numbers: inputs 0 and 1, inputs 2 and 3, inputs 4 and 5, etc.

Input Delays

ON Delay

An input signal is treated as being OFF during the ON delay setting time (0 to
126 ms, in increments of 6 ms) after the input contact’s rising edge. The input
will turn ON only if the input contact remains ON after the ON delay time has
elapsed. This helps prevent chattering of the input contacts.

OFF Delay

An input signal is treated as being ON during the OFF delay setting time (0 to
126 ms, in increments of 6 ms) after the input contact’s falling edge. The input
will turn OFF only if the input contact remains OFF after the OFF delay time
has elapsed. This helps prevent chattering of the input contacts.

1-4-3 Safety Outputs

Safety Outputs with Test Pulses (Output Circuit Diagnosis)

When the output is ON, the test pulse is turned OFF for 470 µs in a cycle of
648 ms. Using this function, short-circuits between output signal lines and the
power supply (positive side) and short-circuits between output signal lines can
be detected.

If an error is detected, the safety output data and the individual safety output
status will turn OFF.

IMPORTANT To prevent the test pulse from causing the connected device to malfunction,

pay careful attention to the input response time of the device.

Dual Channel Setting

When both channels are normal, the outputs can be turned ON.

Description of Safety Functions Section 1-4

The status is treated as normal when both channels are normal. If an error is
detected for one channel, the safety output data and the individual safety out­put status will turn OFF for both channels.

Error Recovery

All conditions below are necessary to recover from an error that has occurred
in a

safety output.

• The cause of the error must be removed.

• Error latch time must have passed.

• The output signals to the output I/O tags from the user application that
correspond to the safety output must go inactive.

1-4-4 I/O Status Data

In addition to I/O data, the DST1-series Safety I/O Terminals support status
data to check the I/O circuits. The status data includes the following data, for
which remote I/O communications can be performed.

• Normal Flags (ON when there is no faults in the internal circuit and the
external wiring)

• An AND Flag of the Normal Flags

• Output monitors (the actual output ON/OFF status)

Normal Flags

Normal Flags indicates whether each safety input, safety output, or test output
is normal (normal status: ON, error status: OFF).

1-5 Logic Functions

The DST1-XD0808SL-1 supports logic functions.

1-5-1 Overview

Safety logic control can be easily performed by setting a combination of I/O
data from local I/O terminals and remote I/O data from a Standard Master or
Safety Master with the logic operations supported by the DST1-XD0808SL-1.
In addition, the safety status can be monitored from standard controls by
using the safety output terminals as additional outputs and outputting data
such as error information.

3-2-5 Changing Default Standard I/O Assembly Data (DST1-XD0808SL-1

Only)

With the DST1-XD0808SL-1, a Network Configurator can be used to change
the default standard I/O assembly data (Default Connection Path). This func­tion is enabled for communications with a Standard Master which cannot
change I/O assembly data. This kind of Standard Master can perform stan­dard I/O communications with a Standard Slave using default I/O assembly
data only. This function must be used to perform I/O communications using
other I/O assembly data.

Remote I/O Allocations Section 3-2

CS/CJ-series DeviceNet Unit

A CS/CJ-series DeviceNet Unit can change I/O assembly data, so there is no
need to use this function to change the default standard I/O assembly data.
Even if this function is used to change the data, the CS/CJ-series DeviceNet
Unit settings will be given priority.

Note For details on making these settings, refer to the CS/CJ-series DeviceNet Unit

Operation Manual (Cat. No. W380).

Using a Standard Master That Cannot Actively Change the Default Standard I/O
Assembly Data

Set the initial standard I/O assembly data (Default Connection Path) when
using the Network Configurator to set the configuration.

1,2,3... 1. Open the Edit Device Parameters Window of the DST1-XD0808SL-1.

From Default Connection Path, select the I/O assembly data for the type of
connection (Poll, BitStrobe, COS, Cyclic) to be used for I/O communica­tions with the Standard Master. “Null” means that I/O assembly data is not
to be used, i.e., that the data size is 0 bytes.

2. Download the specified configuration to the DST1-XD0808SL-1.

3. Set the Standard Master so that the connection type (Poll, BitStrobe, COS,
or Cyclic) and I/O data size agree with the settings that were made in step
1 above.

Note “Null” means that I/O assembly data is not used, i.e., that the data size is 0

bytes. The output connection size for a Bit-Strobe connection is always 0
bytes.

Check that extended display is set.

Make selections for the input connection and output
connection to be used.

IMPORTANT • Supply power to both V0 and V1. The states of the relay contacts are

internally monitored from the power supply of V 0.

• Power supply terminal V1 for the outputs is internally monitored. Supply
the voltage in the specified range (20.4 to 26.4 VDC). If the voltage is sup­plied outside this range, voltage will not be supplied to the output circuits.

!WARNING

For the DST1-MRD08SL-1, isolating transformers, such as TR1, that are used to
isolate between overvoltage categories III and II must conform to IEC60742,
and the insulation between the primary input and secondary output must sat­isfy at least the basic insulation standards of overvoltage category III.

One side of the secondary output of the isolating transformer must be
grounded to prevent electrical shock in case of short-circuiting to the ground
or to the frame of the isolating transformer.
To protect the isolating transformer and to prevent electrical shock in case of
short-circuiting to the frame, insert fuses according to transformer specifica­tions, i.e. at points F1, F2, and F3.

For Model DST1-MRD08SL-1, Insert a fuse rated at 3.15 A or less for each out­put terminal to protect safety output contacts from welding.

Confirm the fuse selection with the fuse manufacturer to ensure the depend­ability of the characteristics of the connected load.

Reaction Time Section 6-1

6-1 Reaction Time

6-1-1 Reaction Time Concept

The reaction time is the maximum time required for stopping an output, taking
into account errors that may occur in safety chains (logical connections for
creating safety devices, consisting of input devices, control devices including
remote I/O devices, and output devices). The safety distance is found based
on the reaction time.

6-1-2 Input Reaction Time

The input reaction time is the time from when an input terminal signal is
changed until an output is sent to the network. The input reaction time is
determined as follows:

Input reaction time = 16.2 ms + Input ON/OFF delay time

The input reaction time for the safety input logic result of the DST1­XD0808SL-1 is as follows:

Input reaction time = 22.2 ms + Input ON/OFF delay time

Note For details on reaction times for the entire system, refer to the DeviceNet

Safety System Configuration Manual (Cat. No. Z905).

6-1-3 Output Reaction Time

The output reaction time is the time from when a network signal is received
until the output terminal is changed. The output reaction time is determined as
follows:

Output reaction time (DST1-MD16SL-1) = 6.2 ms

Output reaction time (DST1-MRD08SL-1) = 26.2 ms

Output reaction time (DST1-XD0808SL-1) = 6.2 ms + Output ON/OFF
delay time

Note For details on reaction times for the entire system, refer to the DeviceNet

Safety System Configuration Manual (Cat. No. Z905).

6-1-4 Local Input and Local Output Reaction Times

The DST1-XD0808SL-1 can stop local outputs according to local input status
by using logic operations. In such cases, the Unit can independently calculate
the reaction time.

Local input or output reaction time = 18.7 ms + Input ON/OFF delay
