6.9.3 Other HCI-HAO features
 Planar transformer for galvanic isolation from HART bus.
 Malfunctioning of the HCI-HAO card (or any linked cards) is reveiled
on the HART bus by means of the device status.
 If any fatal errors occur during operation - which will run the program
into an undesired situation - then a software reset (Warm Reset) is
given to the HCI-HAO software. During this situation, the output of
the module remains at the desired level till the software starts normal
working. Handling of a fatal error is a general FlexConn function.
This will update the appropriate entity as well.
 Unit conversions for the linked variables are possible. All the linked
variables available through linking (data read from other FlexConn
boards) are in SI units. Accepted units are listed in the table below.
 Analog output read back mechanism, which is used to indicate any
errors in the analog output section. An error can be indicated using
the control relay on the FII-DO module over the CAN bus. If some
error is found in the DAC read back, then the same is updated in
function 2 (sensor) health, as per following details in status and
status codes:
 Active and Passive mode of operation for Loop current.
 Multi-drop mode supported to connect more than one HART-
compatible device on HART bus. For operating the device in Multi-
Drop mode, user needs to select the polling address to a non-zero
value. Making the polling address to a non-zero value makes the
output current mode to
Fixed_4_20_MA (4 mA fixed). Non-zero polling
address will automatically make the output current mode to
Fixed_4_20_MA.
