M8130-M8132 Disconnect User Communication Connection [Ladder program only]
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. This function cannot be used when FBD program is selected as
the programming language. 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 (SmartAXIS without Ethernet port) when these relays are turned on.
M8144 Timer Interrupt Status [Ladder program only]
When timer interrupt is enabled, M8144 is turned on. When disabled, M8144 is turned off.
This function cannot be used when FBD program is selected as the programming language.
M8150 Comparison Result 1 [Ladder program only]
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 Chapter 7 "Data Comparison Instructions" - "Special Internal Relays M8150, M8151, and M8152
in CMP=" in the "SmartAXIS Ladder Programming Manual".
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 Chapter 7 "Data Comparison Instructions" - "Special Internal Relays M8150, M8151, and
M8152 in ICMP>=" in the "SmartAXIS Ladder Programming Manual".
This function cannot be used when FBD program is selected as the programming language.
M8151 Comparison Result 2 [Ladder program only]
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 Chapter 7 "Data Comparison Instructions" - "Special Internal Relays M8150, M8151, and M8152
in CMP=" in the "SmartAXIS Ladder Programming Manual".
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 Chapter 7 "Data Comparison Instructions" - "Special Internal Relays M8150, M8151, and
M8152 in ICMP>=" in the "SmartAXIS Ladder Programming Manual".
This function cannot be used when FBD program is selected as the programming language.
M8152 Comparison Result 3 [Ladder program only]
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 Chapter 7 "Data Comparison Instructions" - "Special Internal Relays M8150, M8151, and M8152
in CMP=" in the "SmartAXIS Ladder Programming Manual".
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 Chapter 7 "Data Comparison Instructions"
- "Special Internal Relays M8150, M8151, and M8152 in ICMP>=" in the "SmartAXIS Ladder Programming Manual".
This function cannot be used when FBD program is selected as the programming language.
M8154: Write Data Register values to ROM
This special internal relay is used for the data register ROM backup. When M8154 is on at the end of scan, the values of all data
registers are written to ROM. After writing values, the execution status is stored in D8133 and M8154 turns off. For details, see
Chapter 5 "Special Functions" – "Data Register ROM Backup" on page 5-9.
M8155: Read Data Register values from ROM
This special internal relay is used for the data register ROM backup. When M8155 turns on at the end of scan, the values in the
corresponding ROM are read and stored in the data registers specified by D8184 (start address to read) and D8185 (number of
registers to read). After reading values, the execution status is stored in D8133 and M8155 turns off. For details, see Chapter 5
"Special Functions" – "Data Register ROM Backup" on page 5-9.
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 "High-Speed Counter" on page 5-13.
