Monitoring the Contact Operation Counters
Description
A DST1-series Safety I/O Terminal totals the number of times each safety
input contact, test output contact, and safety output contact turns ON and
internally saves the data in non-volatile memory. If the value of a counter
reaches the threshold value, the Connected Component Maintenance Flag in
General Status will turn ON.
• Measurement count:
0 to 4,294,967,295 counts
(stored data: 0000 0000 to FFFF FFFF hex)
• Measurement unit:
Operations
• Maximum resolution:
166.7 Hz
The user can monitor this information using the Network Configurator and
explicit messages.
Note
• One contact cannot be used at the same time for both the time and
count monitoring functions. Select only one of these in the
Mainte-
nance Counter Mode Choice
.
• If the
Maintenance Counter Mode Choice
