2085-IF4 channel configuration page
After adding the 2085-IF4 expansion module to the controller project, four
Channel <x>
nodes are created on the 2085-IF4
page. Select Channel <x>
to view and configure the channel settings.Setting | 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:
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:
The default setting is Engineering units . |
Input filter | Specifies the input filter type for the channel. Options are:
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. |
