M8000: Start Control M8000 controls the run/stop status of the ladder program. When M8000 is on, the user program is run. When M8000 is off, the user program is stopped. The run/stop status is determined by M8000 and by using the stop/reset input function. For details, see Chapter 1 “Run/Stop the User Program” on page 1-19. M8000 maintains its status when the FT2J is powered down. When data to be maintained during a power failure disappears, the ladder program restarts operation as selected in Function Area Settings > Run/Stop Control > Run/Stop Selection at Keep Data Error or Watchdog Timer Error. For details, see Chapter 28 “Run/Stop Selection at Keep Data Error or Watchdog Timer Error” in the WindO/I-NV4 User’s Manual.
M8001: 1-sec Clock Reset While M8001 is on, M8121 (1-sec clock) is always off.
M8002: All Outputs OFF While M8002 is on, all outputs are off. The self- holding circuit created in the ladder program is also off.

M8000: Start Control M8000 controls the run/stop status of the FC6A. The CPU is set to run when M8000 is turned on, and the CPU is set to off when M8000 is turned off. See Chapter 1 “Run/Stop the User Program” on page 1-19. However, the function switch, stop input, and reset input have precedence over start control. M8000 maintains its status when the CPU is powered down. When data to be maintained during a power failure disappears after the CPU has been off for a period longer than the battery backup duration, the CPU restarts operation as selected in Configuration > Run/Stop Control > Run/Stop Selection at Keep Data Error. For details, see Chapter 5 “Run/Stop Selection at Keep Data Error” in the “FC6A Series MICROSmart User’s Manual”.

M8001: 1-s Clock Reset While M8001 is on, M8121 (1-s clock) is always off.

M8002: All Outputs OFF While M8002 is on, all outputs are off. The self- holding circuit created in the ladder program is also off.

M8003: Carry/Borrow When a carry (Cy) or borrow (Bw) results from executing an addition or subtraction instruction, M8003 is turned on. For details, see Chapter 3 “Carry and Borrow” on page 3-10″.

M8014: Calendar/Clock Data Read Error Flag When an error occurs while calendar/clock data is read from the internal clock to the special data registers (D8008 to D8021), M8014 is turned on. It is turned off when reading completes normally.
M8016: Calendar Data Write Flag When M8016 is turned on after writing data to the calendar data (write-only) special data registers (D8015 to D8018), the calendar data (year, month, day, day of the week) is written to the internal clock.
M8017: Clock Data Write Flag When M8017 is turned on after writing data to the clock data (write-only) special data registers (D8019 to D8021), the clock data (hours, minutes, seconds) is written to the internal clock.
M8020: Calendar/Clock Data Write Flag When M8020 is turned on after writing data to the calendar/clock data (write-only) special data registers (D8015 to D8021), the calendar data (year, month, day, day of the week) and the clock data (hours, minutes, seconds) is written to the internal clock.
M8021: Clock Data Adjust Flag When M8021 is turned on, the clock is adjusted with respect to seconds. When M8021 is turned on, if the seconds are between 0 and 29, the seconds will be set to 0 and the minutes remain the same. When M8021 is turned on, if the seconds are between 30 and 59, the seconds will be set to 0 and 1 will be added to the minutes.
M8022: User Communication Receive Instruction Cancel Flag (Port 1) While M8022 is on, user communication (receive instruction) executing on Port 1 is canceled.
M8023: User Communication Receive Instruction Cancel Flag (Port 2) While M8023 is on, user communication (receive instruction) executing on Port 2 is canceled.
M8024: BMOV/WSFT Executing Flag While the WSFT (word shift) instruction or the BMOV (block move) instruction is executing, M8024 is turned on. When completed, M8024 is turned off.
M8025: Maintain Outputs While Stopped When the FC6A is stopped while running with M8025 turned on, the outputs maintain their runtime status. When set to run again, M8025 is automatically turned off.

M8153 to M8160: Catch Input ON/OFF Status When the rising or falling input edge of the input contact specified as the catch input is detected during a scan, the input contact status is captured. The detectable edges are once per scan. M8153 = Group 1/I0 status M8154 = Group 2/I1 status M8155 = Group 3/I3 status M8156 = Group 4/I4 status M8157 = Group 5/I6 status M8160 = Group 6/I7 status
M8172 to M8175: Transistor Source Output Overcurrent Detection When overcurrent output occurs in a transistor protection source output on the CPU module, a special internal relay (M8172 to M8175) is turned on. The following special internal relays have been allocated with four outputs set as one group. If overcurrent output occurs in any of the special internal relays, it is turned on. Even if the overcurrent output has been cleared, these special internal relays are not reset to off. To reset a special internal relay to off, create programming to do so in the ladder program. M8172 = Group 1 (Q0 to Q3) status M8173 = Group 2 (Q4 to Q7) status M8174 = Group 3 (Q10 to Q13) status M8175 = Group 4 (Q14 to Q17) status
M8184: Change HMI Module Network Settings Trigger When M8184 is turned on, the values stored in D8437 to D8456 are set as the HMI module IP address. The IP address is not set just by changing the values of D8437 to D8456. For details on changing the HMI module network settings, see Chapter 3 “Network settings by HMI module special data registers” in the “FC6A Series MICROSmart Communication Manual”.
M8185: In Daylight Saving Time Period When the daylight saving time function is enabled, M8185 is on during the daylight saving time period. When outside of the daylight saving time period, M8185 is off.
When the daylight saving time function is disabled, M8185 is off.
M8186: Ethernet Port 1 Executing Auto Ping M8186 is on when the auto ping on Ethernet port 1 is operating. M8186 is off when auto ping is stopped. For details on auto ping, see Chapter 3 “Auto Ping Function” in the “FC6A Series MICROSmart Communication Manual”.
M8187: Ethernet Port 1 Auto Ping Stop Flag While M8187 is on, the auto ping on Ethernet port 1 is stopped. While M8187 is off, auto ping is executed. At that time, auto ping is executed from the smallest remote host number specified in the remote host list, regardless of the previous end status.
M8190: Change CPU Module Ethernet Port 1 Network Settings Trigger When M8190 is turned on, the values stored in D8303 to D8323 are set as the IP Settings/DNS Settings of Ethernet port 1 on the CPU module. The IP address is not set just by changing the values of D8303 to D8323. For details on changing the IP Settings/DNS Settings of Ethernet port 1 on the CPU module, see Chapter 3 “Network settings by special data registers” in the “FC6A Series MICROSmart Communication Manual”.
M8191: SNTP Acquisition Flag When M8191 is turned on, the time information is acquired from the SNTP server.
M8192 to M8197: Interrupt Input Edge These relays turn on when an interrupt occurs with the rising edge of an interrupt input. They turn off when an interrupt occurs with the falling edge of an interrupt input.
