Channels view parameters (5034-OF4IH)

The
Channels
view include these parameters:
Parameter
Description
Channel
Displays the channel number to which this configuration applies.
Disable
Determines whether the channel is disabled. Disable channels to prevent erroneous fault reporting, such as No Load or Open Wire faults, and to prevent the fault indication from the channel status indicator.
Output Type
Sets the output type for the channel. Available options are:
  • Voltage
  • Current
Output Range
Sets the output range for the output type. Ranges vary based on the selected Output Type.
Enable HART
Enables communication to HART devices.
Output State During Program Mode
Determines the channel action when the controller transitions to Program Mode or Inhibit mode.
  • Hold Last State causes the output to remain at the last value that is sent from the controller before being placed in Program Mode or Inhibit mode.
  • User Defined Value forces the output to whatever value is entered in the field. The value is entered on Chxx in the engineering units defined by the scaling parameters for the channel.
Output State During Communication Fault Mode
Determines the channel action when a communication fault occurs.
  • Hold Last State causes the output to remain at the last value that is sent from the controller before loss of communication.
  • User Defined Value forces the output to whatever value is entered in the field. The value is entered in the engineering units defined by the scaling parameters for the channel.
Enable No Load Detection
Determines whether No Load Detection is enabled for the channel.
  • If selected, module detects when a wire is disconnected from the channel or a missing load for the output channel.
  • If cleared, the module does not detect when a wire is disconnected from the channel or a missing load for the output channel.
IMPORTANT:
This option is available only if the Input Type is Current.
High Signal
Sets one of the four constants in the scaling equation. High Signal is in terms of the input signal units and corresponds to High Engineering when scaled.
Low Signal
Sets one of the four constants in the scaling equation. Low Signal is in terms of the input signal units and corresponds to Low Engineering when scaled.
Engineering Units
Sets the unit of measurement for High Engineering and Low Engineering.
High Engineering
Sets one of the four constants in the scaling equation. High Engineering corresponds to High Signal and helps determine the engineering units that the signal values scale into.
Low Engineering
Sets one of the four constants in the scaling equation. Low Engineering corresponds to Low Signal and helps determine the engineering units that the signal values scale into.
Recalculate Units
Recalculates new values to the following configuration parameters in Engineering Units based on the new Scaling constants.
  • Low Clamp
  • High Clamp
  • User Defined Value in Program Mode
  • User Defined Value in Fault Mode
  • Final Fault State Value
  • Ramp Rate
  • Channel Offset
TIP: This option is enabled when any of the four Scaling constants is changed.
