CAUTION:
Avoid writing <=>
continuously,
such as ramping
set points or
repetitive loops, to
the Series 996-999
EEPROM memory.
Continuous writes
may result in
premature control
failure, system
downtime and
damage to
processes and
equipment.
NOTE:
The number of
decimal places
returned by many
of these com-
mands is deter-
mined by the
DEC1, DEC2, IN1
or IN2 setting.
