3-1 Set I/O Parameters
The DST1-series Safety I/O Terminals have five parameter groups: General
Parameters, Safety Input Parameters, Test Output Parameters, Safety Output
Parameters, and Operating Time Parameters.
The settings in each parameter group are listed in the following tables. All parameters
are set using the Network Configurator.
Note: Parameters directly related to safety are marked with (s) in the left column.
3-1-1 General Parameters
Parameter name Value Description Default
S Safety Output Error
Latch Time
0 to 65,530 ms
(in increments of
10 ms) This parameter is common to all the
safety outputs.
It sets the time to latch the error state
when an error occurs in these outputs.
Even when the cause of the error has
been removed, the error state will remain
latched for the time set here. 1,000 ms
S Safety Input Error
Latch Time
0 to 65,530 ms
(in increments of
10 ms) This parameter is common to all safety
inputs and test outputs.
It sets the time to latch the error state
when an error occurs in these
inputs/outputs. Even when the cause of
the error has been removed, the error
state will remain latched for the time set
here. 1,000 ms
Clear OFF Test Output Idle
State
Keep output data
This parameter is common to all test
outputs for which the Test Output
Channel Mode is set to
Standard Output .
It sets the output state of the test output
when idle data is received.
Clear
OFF
Unit Name 32 characters max. This parameter sets a user-chosen name
for the DST1-series Safety I/O Terminals.
The set name is saved in the
DST1-series Safety I/O Terminals and
displayed in the network configuration. None
Threshold Network
Power Voltage 8.0 to 30.0 V This parameter sets the threshold of the
network power voltage. When the voltage
falls below the set threshold voltage, the
corresponding bit in general status turns
ON. 11 V
Threshold Run Hours 0 to 429,496,729
hours
This parameter sets the threshold for unit
operating hours. When the operating
hours exceeds the set threshold, the
corresponding bit in general status will
turn ON.
0 hours
Last Maintenance
date 1972/01/01 to
2038/01/19 This parameter saves the maintenance
date in the DST1-series Safety I/O
Terminals.
1972/01/01
