EVICES
■
Inputs (I), Expansion Inputs (I)
Devices that input on/off information from external devices to the FC6A Series MICROSmart.
■
Outputs (Q), Expansion Outputs (Q)
Devices that output on/off information from the FC6A Series MICROSmart to external devices.
■
Internal Relays (M)
Bit devices used internally on the FC6A Series MICROSmart.
■
Special Internal Relays (M)
Bit devices used internally on the FC6A Series MICROSmart. Special functions are assigned to each bit.
■
Shift Registers (R)
Bit devices that are used with the SFR instruction and the SFRN instruction. The bit sequence of the data is shifted according to
pulse input.
■
Timer (T)
Timers used internally in the FC6A Series MICROSmart. There are three devices: Timer bits (symbol: T, unit: bit), timer preset
values (symbol: TP, unit: word), and timer current values (symbol: TC, unit: word).
These can be used as an on-delay timer or an off-delay timer. For details on timers (T), see "Using Timer or Counter as Source
Device" on page 3-6.
■
Counters (C)
Counters used internally in the FC6A Series MICROSmart. There are three devices: Counter bits (symbol: C, unit: bit), counter
preset values (symbol: CP, unit: word), and counter current values (symbol: CC, unit: word). These can be used as an adding
counter or a reversible counter. For details on counters (C), see "Using Timer or Counter as Source Device" on page 3-6.
■
Data Registers (D)
Word devices that are used for writing numerical data internally in the FC6A Series MICROSmart. These can also be used as bit
devices.
■
Special Data Registers (D)
Word devices that are used for writing numerical data internally in the FC6A Series MICROSmart. Special functions are assigned
to each data register. These can also be used as bit devices.
Notes:
•
Although the device symbol for internal relays (M0000 to M7997, M10000 to M21247) and special internal relays (M8000 to M9997) is the
same ("M"), the device characteristics are different. Special functions are assigned to each bit of the special internal relays.
•
Although the device symbol for the data registers (D0000 to D7999, D10000 to D61999, D70000 to D269999) and special data registers
(D8000 to D8899) is the same ("D"), the device characteristics are different. Special functions are assigned to each special data register.
