1-4 User I/O
The ID Controller is equipped with two user outputs that can be turned ON/OFF
by a command from the host controller, and also two user inputs whose ON/OFF
status can be read. These I/Os can be manipulated independently of each other,
so that ON/OFF signals can be processed easily and at low cost by a host com-
puter. The following figure shows an example in which the ID Controller is used
for batch reading of test data.

Outline of Operation
1, 2, 3... 1. When there is a workpiece to be tested, the PC controlling the line instructs
the conveyor to stop the workpiece at a predetermined place.
2. When the workpiece has been stopped, the PC issues a signal indicating
that the line control action has been completed.
3. A host computer reads the signal to the ID Controller through a user input,
and reads the test data.
4. When the test data has been read, the host computer issues a data collec-
tion completion signal through the user output of the ID Controller.
5. In response to the data collection completion signal, the PC sends the work-
piece to the next process.
