Convenient Functions
Calendar/Clock
The FC6A Series MicroSmart features a real-time clock on-board. Using the calendar and clock function, the FC6A Series
MicroSmart can operate according to the current date and time. These functions can be used to control a time schedule for lighting
or air conditioning equipments.
The FC6A Series MicroSmart also supports daylight savings time and the date and time of the switch can be freely set to allow for
use in any region.
User Program Read/Write Protection
The user program in the FC6A Series MicroSmart can be protected against reading and/or writing by including a password in the
user program. This function is effective for security of user programs.
"Keep" or "Clear" Designation of FC6A Series MicroSmart Data
This function specifies whether or not to keep FC6A Series MicroSmart device values when there is a power interruption.
Devices that can be specified as kept are internal relays, shift registers, counter current values, and data registers.
RUN/STOP Selection at Startup when "Keep" Data is Lost
When the backup battery is dead, all data to be kept are lost. The user can select whether the FC6A Series MicroSmart starts to
run or not to prevent undesirable operation at the startup.
Log Data
Device values of the FC6A Series MicroSmart can be saved as CSV files on the SD memory card. The DLOG instruction saves device
values to the SD memory card. The TRACE instruction accumulates device values at each scan and saves them to the SD memory
card at the desired timing.
Constant Scan Time
The variations in scan time that occur when the user program is running can be made constant.
Timer Interrupt
The timer interrupt can be used to call an interrupt program at a predetermined interval of time without being affected by the scan
time.
Script Function
This function allows programming complicated processing with conditional branching, logical operations, arithmetic operations,
and functions as text. Devices can also be read and written. Execute scripts using the SCRPT instruction.
Recipe Function
This function allows the values of device settings to be written to a CSV file to create a recipe file. The values of device settings can
be read from a recipe file and reflected in the FC6A Series MicroSmart devices.
Applicable devices are word devices such as timers, counters, and data registers.
SNTP Function
The current time can be acquired from an SNTP server.
USB Boot Function
This function starts the FC6A Series MicroSmart with power supplied from the USB cable.
This allows the user program and system software to be updated.
During USB boot, USB communication and the SD memory card can be used.
PID Control Function
PID control performs temperature control and other types of control using a PID (proportional-integral-derivative) calculation
algorithm. The FC6A Series MicroSmart can perform PID control by automatically calculating the optimal PID value using the auto
tuning function.
Function Switch
The FC6A Series MicroSmart is equipped with a function switch which can be used to run or stop the user program. The button can
be used for any desired purpose by using the on/off status of the function switch stored in the special internal relay.
