Group Monitor Stop Bits: Sampling will be stopped if the bit is turned
ON from the PLC.
Group Memory Overflow Flags: The flag will turn ON if the number of sam-
pled alarms exceeds the number of records to
store that is set in the NV Configuration. The
flag will remain ON until memory is cleared.
Group Memory Clear Bits: The recorded data will be cleared if the bit is
turned ON from the PLC. Do not turn OFF a
bit until the corresponding Memory Cleared
Flag turns ON.
Group Memory Cleared Flags: The PT will turn ON the corresponding flag
when the memory in the PT has been
cleared. The flag will not turn OFF until the
Memory Clear Bit has been turned OFF.
(1) If the Memory Overflow Flag turns ON, the Memory Clear Bit is turned ON
to clear memory contents.
