Operation and I/O Design

Operation and I/O Design Operation and I/O Design Operation and I/O Design
In General, looking at an old type hopper scale design, the simplest indicator only
displayed the weight value, other system devices communicated the control signal with
each I/O interface. And the key operations and monitoring the system were controlled
separately.
The indicator AD-4402 has an I/O interface to control the system, sub-display to
monitor system information, main display to display weighing data and keys to control
the system, in one unit.
The indicator is designed so as to be able to select arbitrary keys and terminals to
control the system from the front panel keys and the I/O interface with the menu
function. The function of keys and terminals can be designed in the same way.
The system information of the sub-display can be selected in at the function list.

Suppose that the I/O, keys and sub-display are as follows:
Batch start:
Emergency stop key:
Dribble signal :
Batch finish signal :
Not used recipe code
Use default setting for the sub-display
Setup
Step 1 Enter the function list.
Step 2 Select the menu F1 key.([Function] - [Function setting] - [General] - [Other] - [F1 key])
Step 3 Select [6] of
Step 4 Select [13] of
Step 6 Select the menu terminal B1.
([Function] - [Function setting] - [Control I/O Function] - [Output] - [OUT (B1)])
Step 8 Select [6] of
Step 9 Select [14] of
Step 10 Set [6] of "Not used recipe code" at
([Function] - [Function setting] - [Sequence] - [Basic] - [Recipe mode])
Step 11 Select [0] of the default menu and store it.
([Function] - [Function setting] - [General] - [Sub-display] - [Weighing display])
Step 12 Press the ESC key several times to return to the weinghing mode.
Operation and Response
When the F1 key is pressed, a batch weighing is started and terminal B1 works.
When the F2 key is pressed, batch weighing is stopped.
When the final weight has been achieved, terminal B2 is turned on.
