Setting of system information (control devices)

When a bar code reader is connected, the system information (control devices) are required to
be set.
Set the system information in "Common Setting" in the screen creation software.
Bar code input
Bar code input invalid
Bar code input read completed b6 of "head read device"
- Bar code input (GOTà PC)
Because this signal becomes ON when the data read by the bar code reader is stored in
the PC, the write timing can be confirmed using this signal. To set to OFF this bar code
input signal, set to ON the bar code input read completed signal.
- Bar code input read completed (PC à GOT)
This signal sets the bar code input signal from ON to OFF.
- Bar code input invalid (PC à GOT)
When this bit becomes ON after a bar code is input, the bar code input becomes invalid.
The data read by the GOT is cleared.
