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 "n" ("2n" in 32-bit operation) devices starting from , , and/or exceed the
corresponding device range (error code: K6706)
• When "n" ("2n" in 32-bit operation) devices starting from overlap "n" ("2n" in 32-bit operation)
devices starting from (error code: K6706)
• When "n" ("2n" in 32-bit operation) devices starting from overlap "n" ("2n" in 32-bit operation)
devices starting from (error code: K6706)
Program example
In the program shown below, the constant "8765" is subtracted from the data stored in D100 to D102 when
X010 is set to ON, and the operation result is stored in D200 and later.
