M8132 High-speed Counter 1 (I0-I2) Current Value Underflow (ON for 1 scan)
When the current value of high-speed counter 1 drops blow 0 while two-phase high-speed counter is enabled, M8132 turns
on for one scan.
M8133 High-speed Counter 2 (I3) Comparison ON Status (ON for 1 scan)
When the current value of high-speed counter 2 reaches the preset value, M8133 turns on for one scan.
M8134 High-speed Counter 3 (I4) Comparison ON Status (ON for 1 scan)
When the current value of high-speed counter 3 reaches the preset value, M8134 turns on for one scan.
M8135 High-speed Counter 4 (I5-I7) Reset Status (ON for 1 scan)
When reset input I5 is turned on while high-speed counter 4 is enabled either in two-phase or single-phase high-speed
counter mode, M8135 turns on for one scan to indicate that the high-speed counter 4 current value is reset. When reset
input special internal relay M8046 is turned on, M8135 does not turn on.
M8136 High-speed Counter 4 (I5-I7) Current Value Overflow (two-phase high-speed counter) (ON for 1 scan)
High-speed Counter 4 (I5-I7) Comparison ON Status (single-phase high-speed counter) (ON for 1 scan)
When the current value of high-speed counter 4 exceeds 65535 while two-phase high-speed counter is enabled, M8136
turns on for one scan.
When the current value of high-speed counter 4 reaches the preset value while single-phase high-speed counter is enabled,
M8136 turns on for one scan.
M8137 High-speed Counter 4 (I5-I7) Current Value Underflow (ON for 1 scan)
When the current value of high-speed counter 4 drops blow 0 while two-phase high-speed counter is enabled, M8137 turns
on for one scan.
M8140, M8141, M8142, M8143 Interrupt Input Status
When interrupt inputs I2 through I5 are enabled, M8140 through M8143 are turned on, respectively. When disabled, these
internal relays are turned off.
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 operand designated by S1 is greater than that
of operand designated by S2 (S1 > S2). See page 10-2.
When the ICMP>= instruction is used, M8150 is turned on when the value of operand designated by S2 is greater than that
of operand designated by S1 (S2 < S1). See page 10-4.
M8151 Comparison Result Equal To
When the CMP= instruction is used, M8151 is turned on when the value of operand designated by S1 is equal to that of
operand designated by S2 (S1 = S2). See page 10-2.
When the ICMP>= instruction is used, M8151 is turned on when the value of operand designated by S3 is greater than that
of operand designated by S2 (S3 > S2). See page 10-4.
M8152 Comparison Result Less Than
When the CMP= instruction is used, M8152 is turned on when the value of operand designated by S1 is less than that of
operand designated by S2 (S1 < S2). See page 10-2.
When the ICMP>= instruction is used, M8152 is turned on when the value of operand designated by S2 is less than that of
operand designated by S1 and greater than that of operand designated by S3 (S1 > S2 > S3). See page 10-4.
M8154, M8155, M8156, M8157 Catch Input ON/OFF Status
When a rising or falling input edge is detected during a scan, the input statuses of catch inputs I2 through I5 at the moment
are set to M8154 through M8157, respectively, without regard to the scan status. Only one edge is detected in one scan.
For the catch input function, see page 5-18.
