Grid Frequency area

Make the required choice in the Grid frequency drop-down menu.

Deactivate CJ channel area

Mark the Deactivate CJ channel check box if the Cold Junction channel shall not

be used and the supervision disabled.

Fix Junction Temperature area

Type the required value in the Fix Junction Temperature text field

Channel parameters tab

The Channel parameters tab shows the user parameters of the module. It shows

Filter time, Signal range and Cold junction temperature.

Channel area

Mark the Deactivate check box if the channel shall not be used.

Make the required choices in the Filter time, Signal range and Cold junction

temperature drop-down menus.

The service control is used for reading acyclic data and is only visible if the module

is configured via a CI840.

Redundancy Tab

The Redundancy Tab is only shown in Commissioning mode.

Module status area

In the Module status area you can see which I/O module that is addressed by

CI840. By clicking the Update button you update the status for which of the I/O

module that are the primary. The module has to be configured via a CI840.

If the AI880A are used in Safety applications there are restrictions on how to

access data and the HART parameter are recommended to be set to Read only.

Device specific HART commands are not predefined and can be implemented as

both read or write commands. If device specific commands are to be used the

parameter has to be set to Full mode.

Note: If the HART routing functionality of AI880A is not restricted by the

modules configuration settings (Read only or Disabled), the operation procedures

must include restrictions for use of this function.

If a write command is sent when the AI880A is in Read only mode the module

will return an error which is reported back to the AI880 DTM. The AI880 DTM

will display an error message “No connection” in the FBB view stating which

command that has failed. The AI880 DTM will also send an error report back to

the HART DTM and it is up to this DTM to decide how to act on the error
