M8125 In-operation Output
M8125 remains on while the CPU is running.
M8130-M8132 Disconnect User Communication Connection
When SmartAxis is connected to a remote host with the user communication client and a special internal relay corresponding to
the connection is turned off to on, the connection is disconnected. Special internal relays M8130 through M8132 are allocated to
connections 1 through 3, respectively.
These relays are enabled only when user communication client is used. These relays have no effect for the user communication
server. Nothing happens for the 12-I/O type (CPU modules without Ethernet port) when these relays are turned on.
M8144 Timer Interrupt Status
When timer interrupt is enabled, M8144 is turned on. When disabled, M8144 is turned off.
M8150 Comparison Result Greater Than
When the CMP= instruction is used, M8150 is turned on when the value of device designated by S1 is greater than that of device
designated by S2 (S1 > S2). See page 4-2 (Advanced Vol.).
When the ICMP>= instruction is used, M8150 is turned on when the value of device designated by S2 is greater than that of
device designated by S1 (S2 < S1). See page 4-6 (Advanced Vol.).
M8151 Comparison Result Equal To
When the CMP= instruction is used, M8151 is turned on when the value of device designated by S1 is equal to that of device
designated by S2 (S1 = S2). See page 4-2 (Advanced Vol.).
When the ICMP>= instruction is used, M8151 is turned on when the value of device designated by S3 is greater than that of
device designated by S2 (S3 > S2). See page 4-6 (Advanced Vol.).
M8152 Comparison Result Less Than
When the CMP= instruction is used, M8152 is turned on when the value of device designated by S1 is less than that of device
designated by S2 (S1 < S2). See page 4-2 (Advanced Vol.).
When the ICMP>= instruction is used, M8152 is turned on when the value of device designated by S2 is less than that of device
designated by S1 and greater than that of device designated by S3 (S1 > S2 > S3). See page 4-6 (Advanced Vol.).
M8160-M8163 Button Input Status
While the ESC button and direction buttons on the SmartAxis Pro are simultaneously pressed, the corresponding special internal
relays M8160 through M8163 turn on. When no buttons are pressed, M8160 through M8163 turn off.
M8166-M8177 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 Chapter 5 “Special Functions” – “High-speed Counter” in the FT1A Series Pro/
Lite User's Manual. For details on the Touch high-speed counter, see Chapter # “Project Settings” – “#.## Functions” – “High-
speed Counter” in the FT1A Series Touch User's Manual.
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 (500 ms on
and 500 ms off).
M8122 100-ms Clock
M8122 always generates clock pulses in 100-ms increments,
whether M8001 is on or off, with a duty ratio of 1:1 (50 ms on and
50 ms off).
M8123 10-ms Clock
M8123 always generates clock pulses in 10-ms increments,
whether M8001 is on or off, with a duty ratio of 1:1 (5 ms on and
5 ms off).
