.
For produce/consume with status the producing/consuming UDTs must be
identical. This means that not only must elements of the UDT be of the same
type but the UDT name itself must be identical in both controllers.
HART
HART variables can be configured on each analogue input and output channel
to monitor the HART field device.
Make sure that your HART field devices support HART command 0 ('read
unique ID') and HART command 3 ('read current and four dynamic
variables'). The AADvance controller uses these commands to communicate
with the HART devices.
The AADvance analogue input and output modules use HART command
#03 to collect data from the field device as specified by Revision 5 of the
HART specification. The extra data available from HART-enabled field
devices is reported to the application in custom data structures:
T9K_AI_HART and T9K_AI_HART_FULL.
The structures supply the following data:
Loop current in milliamps
Process measurement in engineering units
Errors on HART communication seen by the field device
Status of the field device
Time since the most recent update, in milliseconds
You can use the loop current variable for diagnostic checks in the application,
to compare the value of the variable with the value on the 4 to 20 mA loop and
react if there is a discrepancy. You can also monitor the status of the field device
and use this to report diagnostic errors and manual configuration changes.
Bindings and the SNCP
Network
Bindings are based on a producer/consumer model. The controller consuming
the data establishes a binding link with the controller producing the data and
manages all of the sending and receiving of data. It schedules the sending and
receiving of data, sending the diagnostic data, managing the safety response if
IMPORTANT Only use CIP produce/consume between AADvance and ControlLogix
Controllers. For data being exchanged between AADvance Controllers use
bindings and SNCP network.
IMPORTANT The update rate for HART data from field devices is slower than the update
rate for the 4 to 20 mA analogue signal itself. HART data can take a
maximum of 4 seconds to update, depending on the device type and
configuration.
