Function description
Cycle time
management
Minimum cycle time
Makes the cycle time consistent.
Monitoring the cycle time
Monitors the cycle time.
CPU Unit
built-in
functions
Inputs
High-speed
counter
inputs
High-speed pulse inputs
High-speed pulses from devices such as a rotary encoder are counted.
The counted values are stored in the Auxiliary Area.
Interrupt tasks can be executed when target is reached or by range comparison.
Input pulse frequency
measurement
The frequency of pulses input by the PRV instruction is measured.
Interrupt inputs
Relevant interrupt tasks are executed during the cycle when the CPU Unit built-in inputs
turn ON or turn OFF.
Quick-response inputs
Inputs can be read without being affected by cycle time.
Use the quick-response inputs to read signals shorter than the cycle time.

refreshing
Cyclic
refreshing
The CPU Unit’s built-in I/O are cyclically refreshed.
Immediate
refreshing
I/O refreshing by immediate refreshing instructions
Input response times
Input constants can be set for Basic I/O Units.
The response time can be increased to reduce the effects of chattering and noise at input
contacts. The response time can be decreased to enable detecting shorter input pulses.
Outputs
Pulse
outputs
(Models
with
transistor
outputs
only)
Pulse control
A pulse signal is output and positioning or speed control is performed with a servo driver
that accepts a pulse input.
Continuous mode for speed control or independent mode for position control can be used.
There are functions for changing to positioning during speed control and for changing the
target value during positioning.
Origin positioning
Origin searches and origin returns
PWM outputs
(Models with transistor outputs only)
Pulses for which the duty ratio (ratio between ON time and OFF time during one pulse
cycle) can be set are output.
Normal
outputs
Load OFF function
All of the outputs on the CPU Unit’s I/O can be turned OFF when an error occurs in RUN
or MONITOR mode.
Built-in
analog
Analog input
Convert analog signal into digital value range from 0 to 6,000.
Analog output
Convert digital value range from 0 to 6,000 into analog signal.

refreshing
Cyclic refreshing
The Expansion I/O Units and Expansion Units are cyclically refreshed.
Refreshing by IORF
I/O refreshing by IORF instruction
Load OFF function
All of the outputs on Expansion I/O Units and Expansion Units are turned OFF (0000 hex)
when an error occurs in RUN or MONITOR mode.

Input response times
The response time can be increased to reduce the effects of chattering and noise at input
contacts. The response time can be decreased to enable detecting shorter input pulses.
Expansion
Units
Unit error detection
Errors in Expansion Units are detected. The CPU Unit is notified that the Expansion Unit
stopped due to an error.
Memory
management
functions
Holding I/O memory when changing operating modes
The status of I/O memory can be held when the operating mode is changed.
The forced-set/reset status can be held when the operating mode is changed.
Automatic backup to the backup memory
(built-in EEPROM)
Automatic backup of ladder programs and parameter area to the backup memory
(built-in EEPROM)
Communic
ations
Peripheral
USB port
Peripheral bus (toolbus)
For communications with programming device (CX-Programmer).
Serial port (N/NA-type only)
--
Host Link (SYSWAY) communications
Host Link commands can be sent from a PT or a computer to read/write I/O memory, and
perform other operations for PLC.
No-protocol communications
I/O instructions for communications ports (TXD/RXD instructions) can be used for data
transfer with peripheral devices such as bar code readers.
NT Link communications
I/O memory in the PLC can be allocated and directly linked to various PT functions,
including status control areas, status notification areas, touch switches, lamps, memory
tables, and other objects.
Serial PLC Links
Up to ten words per Unit can be shared by up to nine CPU Units, including one Polling Unit
and eight Polled Units.
Note:
Programmable Terminal (PT) cannot be connected.
Modbus-RTU Easy Master function
Modbus-RTU commands are sent by the Modbus-RTU Master function. Modbus slaves,
such as inverters, can be easily controlled with serial communications.
Interrupt
Scheduled interrupts
Tasks can be executed at a specified interval (1.0 ms min., Unit: 0.1 ms).
Interrupt inputs
Interrupt tasks are processed when the built-in input turns ON or OFF.
High-speed counter interrupts
This function counts input pulses with the CPU Unit’s built-in high-speed counter and
executes an interrupt task when the count reaches the preset value or falls within a preset
range (target value or zone comparison).
