M8030-M8061 Special Internal Relays for High-speed Counter
Special internal relays used for the high-speed counter.
For details on the Pro/Lite high-speed counter, see "High-Speed Counter" on page 5-13.
M8070-M8075 Interrupt Input Status [Ladder program only]
Turns on when the corresponding user interrupt is allowed. When interrupt inputs are disabled, these internal relays are turned off.
M8070=Interrupt input I0 status, M8071=Interrupt input I2 status, M8072=Interrupt input I3 status
M8073=Interrupt input I5 status, M8074=Interrupt input I6 status, M8075=Interrupt input I7 status
This function cannot be used when FBD program is selected as the programming language.
M8076 SD Memory Card Access Stop Flag
Access to the SD memory card is stopped when M8076 is turned off to on.
M8080-M8085 Interrupt Input Edge (ON: Rising, OFF: Falling) [Ladder program only]
This flag indicates whether the interrupt input is triggered with a rising edge or falling edge.
This function cannot be used when FBD program is selected as the programming language.
M8090-M8095 Catch Input ON/OFF Status
When a rising or falling input edge is detected during a scan, the input statuses of catch inputs Group 1/I0 through Group 6/I7 at
the moment are set to M8090 through M8095, respectively, without regard to the scan status. Only one edge is detected in one
scan. For the catch input function, see "Catch Input" on page 5-32.
M8100-M8102 User Communication Receive Instruction Cancel Flag [Ladder program only]
When M8100, M8101, or M8102 is turned on, all ERXD instructions ready for receiving user communication through connection 1,
connection 2, or connection 3 are disabled, respectively.
This function cannot be used when FBD program is selected as the programming language.
M8110-M8112 Connection Status
When SmartAXIS and a network device are connected via the maintenance communication server, user communication server/
client, or Modbus TCP server/client, the connection status turns on. When no network devices are connected, the connection
status turns off.
These relays are always off for the 12-I/O type (SmartAXIS without Ethernet port).
M8120 Initialize Pulse
When the CPU starts operation, M8120 turns on for a period of one scan.
M8121 1-sec Clock
While M8001 (1-sec clock reset) is off, M8121 generates clock
pulses in 1-sec increments, with a duty ratio of 1:1 (500ms on and
500ms off).
M8122 100-ms Clock
M8122 always generates clock pulses in 100ms increments,
whether M8001 is on or off, with a duty ratio of 1:1 (50ms on and
50ms off).
M8123 10-ms Clock
M8123 always generates clock pulses in 10ms increments,
whether M8001 is on or off, with a duty ratio of 1:1 (5ms on and
5ms off).
M8124 Timer/Counter Preset Value Changed
When timer or counter preset values are changed in the CPU module RAM, M8124 turns on. When a user program is
downloaded to the CPU from WindLDR or when the changed timer/counter preset value is cleared, M8124 turns off.
When a timer or counter is designated as a destination of an advanced instruction, the timer/counter preset value is also changed.
M8125 In-operation Output
M8125 remains on while the CPU is running.
