1) The choices offered depend on the modules fitted and/or the options activated. See chap. 8.10.4 and chap. 8.16.
2) Function possible only for the DO1 and DO2 outputs on the M0:MAIN board
MODE: Choose the switching operating for the digital output selected.
configuring in "on/off" operating
PV: Choose a process input with 2 states, ON or OFF, associated with the output.
One of the "PVs" on the M0:MAIN board, available in "On/Off" operating, is the "warning" event. Such
an event is generated when the calibration date expires and/or during the monitoring of certain process
parameters (see chap. 8.11.8, 8.11.9. and 8.12.4 to 8.12.6). When the "warning" event is associated with
a digital output, the output switches whenever such an event is generated by the multiCELL. See also
chap. 9.3
One of the "PVs" in the conductivity module, available in "On/Off" operating, is "USP" (see
chap. 8.10.24).
INVERT: Invert the output or not.
DELAY: Choose the value of the time-out before the output is switched.
configuring in "hysteresis" operating
The output status changes when a threshold is reached:
• by increasing process input value, the output status changes when the high threshold is reached.
• by decreasing process input value, the output status changes when the low threshold is reached.
