Valid Values
Ch[x].InputRange
SINT
Channel’s operating range.
• 0 = -10…10V
• 1 = 0…5V
• 2 = 0…10V
• 3 = 0…20 mA (default)
Ch[x].NotchFilter
SINT
Notch Filter removes line noise for the channel.
There is a relationship between this setting and the RPI
setting. For more information on Notch Filter, see
• 0 = 10 Hz
• 1 = 50 Hz
• 2 = 60 Hz (default)
• 3 = 100 Hz
• 5 = 1000 Hz
• 6 = 20 Hz
• 7 = 15 Hz
• 8 = 500 Hz
• 9 = 5000 Hz
• 10 = 5 Hz
Ch[x].AlarmDisable
BOOL
Disables all alarms on the module.
• 0 = Enabled
• 1 = Disabled (default)
Ch[x].ProcessAlarmLatch
BOOL
Latches all Process alarms if they are configured not to
clear until explicitly unlatched.
• 0 = Latching disabled (default)
• 1 = Latching enabled
Ch[x].RateAlarmLatch
BOOL
Latches all Rate Alarms when set so that they do not clear
until explicitly unlatched.
• 0 = Latching disabled (default)
• 1 = Latching enabled
Ch[x]. Disable
BOOL
Disables the channel.
• 0 = Enabled (default)
• 1 = Disabled
Ch[x].Sourcing
BOOL
When in current mode, indicates if channel is Sinking or
Sourcing.
• 0 = Sinking (default)
• 1 = Sourcing
Ch[x].SynchronizeSampling
BOOL
Determines if the sampling of the channel is synchronized
with other channels configured as synchronized.
• 0 = Not synchronized (default)
• 1 = Synchronized
Ch[x].DigitalFilter
INT
Time Constant for a First Order Lag filter.
0…32,767 ms
(0 = default)
