An Example of HI302 Usage
7.4
9. The HART communication should start immediately after the parameter changes to TRUE.
This may be easily checked by the irregular blinking in the green CH#1 LED, according to
the HART transactions. Note that the CH#2 and CH#3 LEDs blink at the ¼ Hz frequency,
to indicate that there is no HIRT block using the channel.
10. See that the BLK_EXEC_STATE parameter, on IDENTIFICATION, moves to UPDATING.
If not, check if the block is being executed. The MODE_BLK.ACTUAL parameter should
be AUTO.
11. After identifying the device and filling up the HIRT block, the HI302 will continually send
the HART 33 command, since this is the polling command by default, by which default the
polling is enabled. See that the BLK_EXEC_STATE parameter must be on UPDATED to
that matter. If not, the initial sequence of HART commands wasn’t executed successfully
and there must be some configuration problem. Watch carefully the parameter values and
check if they correspond to what they are supposed to be, according to the device
installed. Then, all the values available in the block may be read.
