Devices (Sequence CPU and BASIC CPU)
The device names that can be used in PC link commands are given below. In ladder
programs, present values of timers and time-up relays are represented the same way as
in T0001. However, in PC link commands, they are represented differently, as in
TP00001 and TU00001. Although present value of timers are count-down timers in the
FA-M3, you can also use the present value of the count-up timers (TI00001) for display
on a higher-level computer. (This applies similarly to counters).

*1: Present value of count-up timer/counter (=preset value – present value of count-down timer/counter)
*2: Preset values of timers and counters can only be read but cannot be written.
*3: You can access the common area as D registers or I relays on the BASIC CPU (F3BP20-0N/F3BP30-0N).
