2085-IF8 channel configuration page

After adding the 2085-IF8 expansion module to the controller project, eight
Channel <x>
nodes are created on the
2085-IF8
page. Select
Channel <x>
to view and configure the channel settings.

Description
Enable channel
Turns the channel on or off. When the channel is turned on, the settings on the
Channel <x>
page are available.
When the channel is turned off, the input variables of the channel are not removed from the global variable grid.
The channel is turned on by default.
Input range
Specifies the voltage or current input ranges for the channel. Options are:
  • 0 mA to 20 mA
  • 4 mA to 20 mA
  • –10 V to 10 V
  • 0 V to 10 V
When the input range is set to
–10 V to 10 V
,
Data format
must be
Raw/proportional data
or
Engineering units
.
The default setting is
4 mA to 20 mA
.
Data format
Specifies the input format for the channel. Each data format selection has its assigned default values. When your selection changes, the parameters on the
Channel <x>
page update to the default values. Options are:
  • Raw/proportional data
  • Engineering units
  • Percent range
The default setting is
Engineering units
.
Input filter
Specifies the input filter type for the channel. Options are:
  • No filter
  • 2-point moving average
  • 4-point moving average
  • 8-point moving average
  • 50/60 Hz rejection
The default setting is
50/60 Hz rejection
.
Alarm
Alarm limits are configured in descending order from
High high alarm
to
Low low alarm
.
High high alarm
Turns the high high alarm for the channel on or off and sets the limit for the high high alarm. Turn on the alarm if you want to configure the alarm limit. You must turn on
High alarm
to configure
High high alarm
.
By default, the high high alarm is turned off. The default value for the high high alarm limit is
20.999 mA
. You must set the alarm limit to a value that is within the
Input range
you selected. The high high alarm limit must be equal to or greater than the high alarm, low alarm, or low low alarm limit.
The corresponding alarm status bit (HHA#) is set when the input value for the channel surpasses the designated high high alarm limit. The bit is cleared when the input value drops to the same level or below the designated alarm limit.
High alarm
Turns the high alarm for the channel on or off and sets the high alarm limit. Turn on the alarm if you want to configure the alarm limit.
By default, the high alarm is turned on. The default value for the high alarm limit is
20.000 mA
. You must set the alarm limit to a value that is within the
Input range
you selected. The high alarm limit must be equal to or greater than the low alarm limit.
The corresponding alarm status bit (HA#) is set when the input value for the channel surpasses the designated high alarm limit. The bit is cleared when the input value drops to the same level or below the designated alarm limit.
Low alarm
Turns the low alarm for the channel on or off. Turn on the alarm if you want to configure the alarm limit.
By default, the low alarm is turned off. The default value for the low alarm limit is
4.000 mA
. You must set the alarm limit to a value that is within the
Input range
you selected.
The corresponding alarm status bit (LA#) is set when the input value for the channel falls below the designated low alarm limit. The bit is cleared when the input value rises to the same level or exceeds the designated low alarm limit.
Low low alarm
Turns the low low alarm for the channel on or off. Turn on the alarm if you want to configure the alarm limit. You must turn on
Low alarm
to configure
Low low alarm
.
By default, the low low alarm is turned off. The default value for the low low alarm limit is
3.201 mA
. You must set the alarm limit to a value that is within the input range you selected. The low low alarm limit cannot surpass the low alarm limit.
The corresponding alarm status bit (LLA#) is set when the input value for the channel falls below the designated low low alarm limit. The bit is cleared when the input value rises to the same level or exceeds the designated low low alarm limit.
