HI302-O – Configuring the MAO Block
The HI302-O has 8 HART channels in parallel to circuits that control the loop current and
the actuators connected to them. The input parameter value should always be written in
percentage of Span. The following parameters should be configured:
•
MODE_BLK : Set on AUTO.
•
CHANNEL : Standard value equal to 0.
See the Function Block manual for more details on configurations and options.
Starting the HI302 Operation
After configuring the block, download it. Upon the download completion, set the
HCFG.COMM_ENABLE parameter on TRUE to enable the configuration and start the
HART communication.
IMPORTANT
After the download is carried out, the configuration should be saved in the non-volatile
memory. The saving is automatic and starts with the download. It takes around 20
minutes, according to the configuration size. While the yellow LED is lit, the HI302 can’ t
be turned off or reset, or else, a new download is needed.
If the user has devices whose configuration is already in the HI302 memory, go to the
chapter about operation and functioning theory. In case the user has to set a specific
configuration, see the chapter about advanced configuration, first. For more details on how
to configure the HI302, visit our
