These functions are provided by the DST1-XD0808SL-1.
The DST1-XD0808SL-1 provides basic logic parameters, such as AND
and OR. This enables direct control of local outputs from local inputs,
reducing reaction time.
The output time constant can be set from 0 to 300,000 ms, in increments
of 100 ms.
Any of the following outputs can be set: Same or inverse values for safety
output terminal and another safety output, output indicating operating
mode, output indicating normal status, and reset request outputs.
The present, bottom, and peak values for the network power supply volt-
age can be recorded in the DST1-series Terminal.
The total ON time (unit: 0.1 h) of the internal circuit power can be calcu-
lated and recorded in the DST1-series Terminal.
The user can record a name or comment for each DST1-series Terminal,
using up to 32 characters.
The user can record a name or comment for each I/O terminal, using up to
32 characters.
The date on which maintenance was last performed can be written in the
DST1-series Terminal.
Can be used to check whether the I/O power is ON.
Can be used to count the number of times each input or output contact
changes from OFF to ON (maximum resolution of 50 Hz) and to record the
total in the DST1-series Terminal.
Can be used to calculate the total ON time for each input or output contact
(unit: s) and to record the total in the DST1-series Terminal.
Not including test output terminals.
