7: DEVICE ADDRESSES
Introduction
This chapter describes device addresses available for the SmartAXIS. Special internal relays and special data registers are also
described.
The SmartAXIS is programmed using devices such as inputs, outputs, remote inputs, remote outputs, internal relays, timers,
counters, shift registers, and data registers.
Inputs (I) are relays to receive input signals through the input terminals.
Remote inputs (I) are relays to receive input signals from external devices connected to the remote I/O slaves.
Outputs (Q) are relays to send the processed results of the user program to the output terminals.
Remote outputs (O) are relays to send output signals to external devices connected to the remote I/O slaves.
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.
Special data registers (D) are dedicated to special functions.
Device Addresses
Available I/O numbers depend on the type of the SmartAXIS.
Notes:
*1 The least significant digit of input, output, internal relay, and special internal relay device address is an octal number (0 through 7). Upper digits
are decimal numbers.
*2 Out of data registers D0 through D1999, D1000 through D1999 cannot be designated as "keep" types. Retained in STOP→RUN, but zeroed out
when the power is turned on.
*3 When you use data register ROM backup, you can initialize the data registers with the values backed up in ROM. For details, see Chapter 5
"Special Functions" – “Data Register ROM Backup” on page 5-9.
