Parameter
Description
Channel
The channel number to which this configuration applies.
Disable
Select to disable channel configuration or clear to enable channel configuration.
Disable the channel to help prevent erroneous fault reporting, such as open wire fault, and to help prevent the FLT LED for that channel from illuminating.
Sensor Type
Select the sensor type for the channel:
  • Magnetic / Inductive Pickup
  • Vortex Flowmeter
  • 24V DC IEC Type 3
Threshold Voltage
Select the threshold voltage for the channel. Options vary depending on the selected sensor type for the channel:
Sensor type
Options
Magnetic / Inductive Pickup
  • 50 mV AC
  • 75 mV AC
  • 100 mV AC
  • 150 mV AC
  • 250 mV AC
  • 500 mV AC
Vortex Flowmeter
  • 3 V
  • 6 V
24V DC IEC Type 3
11 V DC
Digital Filter (ms)
Enter the time constant for a first order lag filter used to smooth noise transients on the input with a range from 0…32767 milliseconds. When set to 0, no filtering takes place.
Open Wire Detection
Select to turn on open wire detection for the channel or clear to turn off open wire detection for the channel.
This check box is turned off if the sensor type is
Vortex Flowmeter
.
Disable Alarms
Select to disable the module from generating process alarms or rate alarms. Clear to enable the module to generate process alarms or rate alarms.
Diagnostics
Select to open the
Ch0x Diagnostics
 dialog box and view diagnostic information.
Latch fault until reset via output tag
Select to turn on
Latch fault until reset via output tag
 or clear to turn off
Latch fault until reset via output tag
 for all channels.
  • Selected: The I/O channel holds safety input fault indications until it checks if a fault exists. If the fault is removed, the channel only clears the fault status after detecting that the ResetFault, in the channel consume assembly, has a rising edge. Otherwise, the channel continues to check if a fault exists.
  • Cleared: The I/O channel holds safety input fault indications for one second before checking if a fault exists. If the fault is removed, the channel clears the fault status. Otherwise, the channel continues to check if a fault exists.
