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.

All conditions below are necessary to recover from an error that has occurred
in a safety input.
• The cause of the error must be removed.
• The error latch time must have passed.
• The input signal must return to an inactive state and there must be no error condition
detected. (e.g., by pressing the emergency stop switch or opening a door)

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.

Remote I/O AllocationsSection 3-2
From among the I/O data, safety connections for up to four items, including
one output, can be allocated for the Master Unit and standard connections for
up to two items can be allocated for the Master Unit.
IMPORTANT Communications with up to 15 Safety Controllers for each connection can be
performed using multi-cast connection. If four connections are used, however,
only a maximum of 30 Safety Controllers total can communicate with the
DST1-series Safety I/O Terminals. Up to two safety connections can be used
with the DST1-XD0808SL-1.

3-2-5Changing 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.
50
Remote I/O AllocationsSection 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.
NoteFor 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.
Check that extended display is set.
Make selections for the input connection and output
connection to be used.
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.

!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.
70
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.
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.

5-4-6Dimensions
The following figures show the dimensions of the DST1-XD0808SL-1 (unit:
mm).
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.
6-1-2Input 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
NoteFor details on reaction times for the entire system, refer to the DeviceNet
Safety System Configuration Manual (Cat. No. Z905).
6-1-3Output 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
NoteFor details on reaction times for the entire system, refer to the DeviceNet
Safety System Configuration Manual (Cat. No. Z905).
6-1-4Local 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.
