ICMP>= (Interval Compare Greater Than or Equal To)
Applicable CPU Modules
Valid Devices
For the valid device address range, see pages 6-1 and 6-2
(Basic Vol.).
Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
When T (timer) or C (counter) is used as S1, S2, or S3, the timer/counter current value (TC or CC) is read out.
When F (float) data type is selected, only data register and constant can be designated as S1, S2, and S3.
When F (float) data type is selected and S1, S2, or S3 does not comply with the normal floating-point format, a user program execution error will
result, turning on special internal relay M8004 and ERR LED on the CPU module.
When the data of S1 is smaller than that of S3 (S1 < S3), a user program execution error will result, turning on special internal relay M8004 and ERR
LED on the CPU module.
For user program execution errors, see Chapter 4 “User Program Execution Errors” on page 4-21.
Special Internal Relays M8150, M8151, and M8152 in ICMP>=
Three special internal relays are available to indicate the comparison result of the ICMP>= instruction. Depending on the result,
one of the three special internal relays turns on. S1 must always be greater than or equal to S3 (S1
S3).
When more than one ICMP>= or CMP= instruction is used, M8150, M8151, or M8152 indicates the result of the instruction that
was executed last.
Data type W or I:
S1
S2
S3
D1 on
Data type D, L, F:
S1·S1+1
S2·S2+1
S3·S3+1
D1 on
When input is on, the 16- or 32-bit data designated by S1, S2, and S3 are
compared. When the condition is met, destination device D1 is turned on.
When the condition is not met, D1 is turned off.

When a bit device such as I (input), Q (output), M (internal relay), or R (shift register) is designated as the
source, 16 points (word or integer data type) or 32 points (double-word or long data type) are used.
When a word device such as T (timer), C (counter), or D (data register) is designated as the source, 1 point
(word or integer data type) or 2 points (double-word, long, or float data type) are used.
The destination uses only one output or internal relay regardless of the selected data type.

When S2 > S1, M8150 turns on.
When S2 < S3, M8151 turns on.
When S1 > S2 > S3, M8152 turns on.
