CAUTION:
Avoid writing <=>
continuously, such
as ramping set
points or repetitive
loops, to the
Series 981-984
EEPROM memory.
Continuous writes
may result in
premature control
failure, system
downtime and
damage to pro-
cesses and
equipment.
NOTE:
The number of
decimal places
returned by many
of these com-
mands is deter-
mined by the DEC1
or IN1 setting.

apply to Modbus
