Autoscrolling Function - ABB JDF300 Operating Instruction

16 J D F 3 0 0 | F I E L D I N D I C ATO R | O I/ J D F 3 0 0 - E N R E V. B
In case no inputs are enabled, the display will appear as follows:
Where the Diagnostic code 003 and the maintenance icon identify the anomalous condition. Refer to the diagnostic section for
more info about diagnosis capability of the JDF300.
Below are displayed three images relating the steps occurring when the user press the Z button in order to move from an input to
the next one.
At Step 1, when the Z button is released after it has been pressed while the JDF300 displays the IN1 (Linked – IN1L), the JDF300
moves to Step 2. On the display it appears an intermediate view for a couple of seconds having the aim to make evident to the user
that the JDF300 is switching to a new input as displayed at Step 3 relating the next valid input IN3 (Not Linked – IN3N).
Together with the input number, it changes also the Variable's TAG and Unit according at what configured in the HMITB for the new
Step 1
input.
IMPORTANT
The L and N letters after the input number, specify if the displayed variable is received from an upward linked block via Pub/ Sub
communication (L) or if the value is contained in the INx parameter of the MAO block written via Client/Server communication (N)

Autoscrolling Function

The S button is used to enable or disable the Auto scrolling function of the JDF300.
When the "HMI_IN_SEQUENCE" is switched to ON via FF communication or through the S button, the Autoscrolling function is
enabled.
IMPORTANT
While the "HMI_IN_SEQUENCE" is enabled (ON), the Z button stops its function until the "HMI_IN_SEQUENCE" is disabled again.
After the S button is held down for at least 0.5 seconds, when released, it enables or disable the automatic scrolling of the MAO
inputs.
If the "HMI_IN_SEQUENCE" is disabled (OFF), the S button enable the Auto scrolling and its symbol
of the display.
When the Autoscrolling is enabled, the actual "MAO_CHANNEL" remains unchanged for other 6 or 12 seconds after that, according
to the "HMITB_IN_ENABLED" bits, the "MAO_CHANNEL" is written with the number of the next enabled/valid Input.
This condition remains stable for other 6 or 12 seconds after that the same operation above described is repeated again.
After the Input 8 is evaluated and, if necessary, displayed, the next step returns to the Input 1 again.
The two different interval of time of 6 or 12 seconds for the changing of the "MAO_CHANNEL" are user selectable. The
default interval is 6 seconds when the "HMITB_SEQUENCE_SPEED" is set to Fast, while the interval became 12 seconds when
"HMITB_SEQUENCE_SPEED" is set to Slow.
With the device in this condition, the new pressing of the S button writes OFF in the "HMI_IN_SEQUENCE" disabling the automatic
scrolling. The auto scrolling symbol disappear from the display, the "MAO_CHANNEL" remains set to the last input selected before
the "HMI_IN_SEQUENCE" disabling and the Z button returns to execute its normal function.
