22.7.1 Devices in GOT-F900
The table below shows intrinsic devices built in the GOT-F900.
Because these internal devices are not related to the devices of the connected PLC or the
memory of a microcomputer board, they are available without regard to the connected
equipment.
These internal devices in the GOT-F900 can be rewritten by the status monitoring function, the
switch function and the numeric value input function, and used for lamp indicator, numeric
value display, switch condition, etc.
Applicable screen creation software
The GT Designer is available from the first version. The DU/WIN is available from Version 2.50
and later.
