I ntroduction
The SmartAXIS supports many features in addition to instructions/FB.
For functions that require advanced setup including the functions to upload, download, and protect user programs and the network
settings, first configure those settings on the Function Area Settings dialog, and then download the user program to the
SmartAXIS. Constant scan time and forced I/O can be used without advanced setup.
This chapter describes the SmartAXIS special functions, how to configure them, and examples of their use.

The SmartAXIS can be started/stopped with a specified input.
The device values of the SmartAXIS can be cleared with a specified input.
Whether to start or stop the SmartAXIS when the SmartAXIS is powered up
after the "keep" data in the RAM has been lost can be specified.
Whether to start or stop the SmartAXIS regardless of the M8000 status when
the SmartAXIS is powered up can be specified.
Whether to clear or keep the device values, such as counter current values,
when the SmartAXIS starts running can be specified.
Initializes data registers with values backed up in ROM.
The high-speed counters can be used to count input pulses from rotary
encoders or proximity switches regardless of the scan time.
The catch input can be used to receive short pulses from sensors regardless
of the scan time.
When a quick response to an external input is required, such as in positioning
control, the interrupt input can call a subroutine to execute an interrupt program.
The pulse frequency of input signals to input terminals can be counted
regardless of the scan time.
The input filter rejects short input pulses when the SmartAXIS is used with
input signals containing noises.
Analog voltage inputs, such as inputs from pressure sensors, can be read and
stored in special data registers as digital values.
When executing the same program repeatedly regardless of the scan time is
required, the timer interrupt can call a subroutine at specified time interval.
The inputs or outputs of the SmartAXIS can forcibly be turned on or off
regardless of the actual inputs and outputs status.
Communication mode and parameters for each communication port can be
configured for the SmartAXIS to communicate with external devices.
The user program in a memory cartridge can be downloaded to the ROM in
the SmartAXIS when the SmartAXIS is powered on.
DLOG and TRACE instructions/FBs can save the device values in CSV files and
store those files in an SD memory card inserted to the SmartAXIS.

MSG instruction/FB
The order of upper and lower words for 32-bit data can be specified.
The user program in the SmartAXIS can be protected with a password against
the user program upload or download.
The watchdog timer monitors the SmartAXIS operation and the watchdog
time preset value can be changed.
The scan time of the SmartAXIS can be made constant by specifying the
constant scan time.
The internal clock of the SmartAXIS can automatically be adjusted according
to the configured daylight saving time period.
The SmartAXIS can operate according to the current date and time and be
used in applications, such as lighting or air conditioning.
Configuring the network settings of the SmartAXIS is required to connect the
SmartAXIS to the network.
Communication mode and parameters for the Ethernet communication can be
configured for each connection so that the SmartAXIS can communicate with
other network devices over the Ethernet.
The remote host devices on the network that the SmartAXIS communicates
with can be registered and managed in the Remote Host List.
