6 - 126 Service Manual
All the HART-compatible devices connected over the HART bus
must have different polling addresses. Multi-drop mode is supported
only in Passive mode of loop configuration. When the output current
mode is set to
Standard_4_20_MA, the polling address of the device
must be made zero.
 When the device is not in multi-drop mode (
STANDARD_4_20_MA mode
selected) then the output current follows the changes in linked PV
value.
 Scanning of each linked available PV, SV, TV and QV on the CAN-
bus with frequency of 1 Hz. That means all the available linked
variables are scanned every 1 second.
 The analog output is refreshed every 1 second, even if there is no
change in the scanned variables. So, the watchdog for analog output
is automatically implemented. If the output is not refreshed within 45
seconds then a watchdog to analog output is generated and the
output is forced to 0 mA.
 During startup, the analog output of the HCI-HAO module is kept low
(< 0.5 mA). This value will be there till initialization takes place. Once
the normal operation starts the output will follow the linked PV
depending upon the output mode setting.
 Manual overwrite mechanism. This is a standard FlexConn func-
tionality. Separate configuration and command entities are defined
for this. See 6.9.5 - Board Commissioning.
6.9.4 Calibration of the HCI-HAO
A calibration provision is given, which is used to accurately map the
analog output between 4 -20 mA using the two range values entered for
Primary Variable.
Following table lists all entities required for calibration.
NOTE: Commands used in the following calibration
procedure can be executed either by using the CAN
tool, the SmartView, or Engauge.
Calibrate the analog output of the HCI-HAO as follows:
☛ Connect loop resistor at connector CN2
☛ Power up HCI-HAO board
