Operand Allocation Numbers - IDEC FC4A-C10R2 User Manual

LLOCATION
Introduction
This chapter describes allocation numbers available for the
cial internal relays and special data registers are also described.
The is programmed using operands such as inputs, outputs, internal relays, timers, counters, shift registers,
MicroSmart
and data registers.
Inputs (I) are relays to receive input signals through the input terminals.
Outputs (Q) are relays to send the processed results of the user program to the output terminals.
Internal relays (M) are relays used in the CPU and cannot be outputted to the output terminals.
Special internal relays (M) are internal relays dedicated to specific functions.
Timers (T) are relays used in the user program, available in 1-sec, 100-ms, 10-ms, and 1-ms timers.
Counters (C) are relays used in the user program, available in adding counters and reversible counters.
Shift registers (R) are registers to shift the data bits according to pulse inputs.
Data registers (D) are registers used to store numerical data. Some of the data registers are dedicated to special functions.

Operand Allocation Numbers

Available I/O numbers depend on the type of the
ules can be used with only the 24-I/O type CPU module among all-in-one type CPU modules. All slim type CPU modules
can be used with I/O modules to expand the I/O points. For details of I/O, internal relay, and special internal relay num-
bers, see page 6-3.

Notes:
•
The least significant digit of input, output, internal relay, and special internal relay operand number is an octal number (0
through 7). Upper digits are decimal numbers.
•
The allocation numbers of expansion inputs and outputs start with I30 and Q30, respectively.
•
Note that input and output allocation numbers are not continuous between the CPU module and expansion I/O modules.
•
The 24-I/O type CPU module (FC4A-C24R2 and FC4A-C24R2C) can add a maximum of 64 I/O points, and use a maximum
of 88 points of inputs and outputs in total.
