Maintenance Functions of DST1-series Safety I/O Terminals
Section 1-7
1-7-2
Monitoring the Run Hours
Description
A DST1-series Safety I/O Terminal totals the number of hours the internal cir-
cuit power is supplied and internally saves it in non-volatile memory. If the
cumulative time reaches the set threshold value, the Unit Maintenance Flag
will turn ON in the General Status.
• Measurement time:
0 to 429,496,729.5 hours
(stored data: 0000 0000 to FFFF FFFF hex)
• Measurement unit:
0.1 hour
The user can monitor this information using the Network Configurator and
explicit messages.
Note
• The run hours monitoring function totals the time when the power supply
to the DST1-series Safety I/O Terminal (network power) is ON. This does
not include the time when the power is OFF.
• The DST1-series Safety I/O Terminals measure time internally in 0.1-hour
increments. When the Threshold Run Hours parameter is set on the Net-
work Configurator and when the run hours are monitored, however, the
time will be in 1-hour increments.
