This section describes the functions of the FC6A Series MICROSmart.
I/O Related Functions
Catch Input
The catch input function is used to receive shot pulses (minimum pulse width: 5 μs) that is shorter than the user program scan
time. A maximum of 6 catch inputs can be used.
Note: The scan time is the time duration for executing one cycle of the user program that is cyclically executed.
Input Filter
The input filter is the function to reduce the influence from the bounce or noise on input contacts by adjusting the filter width
according to the input signal width. The input filter of 0 ms (no filter) or 3 to 15 ms (1 ms increments) can be configured for
individual input.
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 digital value in a special data register. There is one built-in analog input.
Analog Potentiometer 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 potentiometer.
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.
