Introduction
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.

Function area
settings
Catch input
The catch input can be used to receive short pulses from sensors regardless
of the scan time.

Interrupt input
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.
5-34
Frequency measurement
The pulse frequency of input signals to input terminals can be counted
regardless of the scan time.
5-36
Input filter
The input filter rejects short input pulses when the SmartAXIS is used with
input signals containing noises.
5-38
Analog input
Analog voltage inputs, such as inputs from pressure sensors, can be read and
stored in special data registers as digital values.
5-39
Timer interrupt
When executing the same program repeatedly regardless of the scan time is
required, the timer interrupt can call a subroutine at specified time interval.
5-41
Forced I/O function
The inputs or outputs of the SmartAXIS can forcibly be turned on or off
