Caution
• When using 32-bit counters (including 32-bit high-speed counters)
For comparing 32-bit counters and 32-bit high-speed counters (C200 to C255), make sure to use an instruction for
32-bit operation (DBKCMP=, DBKCMP>, DBKCMP<, DBKCMP<>, DBKCMP<=, or DBKCMP>=).
If an instruction for 16-bit operation (BKCMP=, BKCMP>, BKCMP<, BKCMP<>, BKCMP<=, or BKCMP>=) is used,
an operation error is caused (error code: K6705).
• Note that the 32-bit value [n+1, n] is valid when D or R is specified as "n" in a 32-bit instruction.
In the case of "DBKCMP = D0 D100 M0 R0", "n" is [R1, R0].
Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in
D8067.
• When the range of "n" ("2n" in 32-bit operation) points starting from
corresponding device range (error code: K6706)
• When the range of "n" points starting from
• When data registers starting from
from S (error code: K6706)
