Numerics used for device Nos.
PC units use the numerics shown in the table below for device Nos.
For example, in an FX PC, device Nos. for input (X) and output (Y) are represented in octal, and device Nos.
for internal relay (M), timer (T), counter (C), etc. are represented in decimal.
Internal devices of the GOT-F900
They are built in the GOT-F900 main unit as intrinsic devices.
The DU/WIN-E whose version is Ver. 2.50 or later supports them.
You can rewrite internal devices of the GOT-F900 using the status observation, switch and numeric input
functions, and use them for the conditions for lamp indication, numeric display and switch.
Because these internal devices are not related to the connected PLC or microcomputer board, they are
available in any connectable PLC (including microcomputer board).
GB 0 to GB 131 and GD 0 to GD 99 are used for the processing inside the GOT-F900.
