Value of 1 will initiate span calibration. Will
R/W 0,1
automatically set back to 0.
Position to which valve plug will be driven upon loss of
signal. Loss of signal is based upon the active control
mode. 0-1000=0-100.0% with 1 implied decimal point.
R/W 0-1001 In on/off mode 0-499 will result in movement to 0%
while 500-1000 will result in movement to 100%. A
value of 1001 in any control mode is the setting for
"lock-in-last."
Time without a valid Modbus message is seen (to any
address) before "loss of signal" motion is engaged
R/W 0-65535 when in Modbus control mode. Only active in Modbus
control mode.
0=disabled
Time without a digital signal being low (contact made)
from either digital input as viewed by voltage level on
the digital input terminals. If neither contact has been
R/W 0-3600 made (pulled input low) within the timeout period, the
valve plug will be moved to the loss-of-signal position.
Only active in the local, on-off, dual contact mode.
0=disabled.
