uint16
Loss of signal position
(100=10.0%)
40050 0 R/W 0-1001
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.
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".
uint16 Modbus timeout (s) 40051 60 R/W 0-65535
Time without a valid Modbus message is seen (to any
address) before "loss of signal" motion is engaged
when in Modbus control mode. Only active in Modbus
control mode. 0=disabled
uint16 Dual contact timeout (s) 40052 60 R/W 0-3600
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
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.
