Interrupt Code
(Hex)
Base Screen
Output when the screens are switched according to the
change in the switching device values assigned to 1/2.

20H
independently without being interlocked.
(Example of output)
When all the switching device values assigned to
the Base Screen and Overlap Window1/2 are
changed, 3 special interrupt codes are output.
21H Output when Numerical/ASCII Input is completed.
Output when Recipe data transfer (read-out, write-in) is
22H
completed.
Output when Bar code, RFID data has been imported
23H
into GOT
(2) Communication detail setting when connecting
multiple GOTs
For the following items, set the same settings to
the n+1th GOT interface as the CH No.1 of n-th
GOT.
• Transmission Speed
• Data Bit
• Stop Bit
• Parity
Set each [Host Address] for the GOT.
(3) Communication interface setting by the Utility
The communication interface setting can be
changed on the Utility's [Communication setting]
after writing [Communication Settings] of project
data.
For details on the Utility, refer to the following
manual.
User's Manual of GOT used.
(4) Precedence in communication settings
When settings are made by GT Designer3 or the
