Special Functions
This section describes the functions of the FC6A Series MicroSmart.
I/O Related Functions
Catch Input
The catch input receives short input pulses from sensors without regard to the scan time. A maximum of 6 catch inputs can be
used.
Input Filter
The input filter can be adjusted, according to the width of input signals, to reject input noises. Selectable input filter values to pass
input signals are 0 ms, and 3 through 15 ms in 1 ms increments. The input filter rejects inputs shorter than the selected input filter
value minus 2 ms. This function is useful for eliminating input noises and bounce in limit switches.
Interrupt Input
The interrupt input can be used to call an interrupt program to respond to an external input that requires a response faster than
the ladder program scan time. A maximum of six interrupt inputs can be used.
Stop and Reset Inputs
The stop input is a function to stop ladder program execution. The reset input is a function to stop ladder program operation and
clear device values. Any input terminal on the FC6A Series MicroSmart can be designated as a stop or reset input to control the
FC6A Series MicroSmart operation.
Built-in Analog Input Function
This function acquires 0 to 10V DC analog input as a 0 to 1,000 digital value in a special data register. There is one built-in analog
input.
Analog Volume Function
This function acquires volume input as a 0 to 1,000 digital value in a special data register according to the position of the volume.
There is one analog volume.
Forced I/O
The inputs and outputs of the FC6A Series MicroSmart can be forced on or off. This function can be used to check the I/O wiring
or the user program operation.
