Description
The 16-bit output value stored in the area specified by D is controlled based on whether or not the 16-bit input
value specified by S3 falls within the range bounded by the upper and lower limits set in S2 and S1.
The output value is determined based on the following conditions:
− When the lower limit S1 is greater than the input value S3, the lower limit value S1 is stored in D as the
output value.
− When the upper limit S2 is less than the input value S3, the upper limit value S2 is stored in D as the
output value.
− When Lower limit S1
Input value S3 Upper limit S2, the input value S3 is stored in D as the
output value.
Output value D
[S2]
[S1]
Input value S3
Lower limit S1
Upper limit S2
To perform upper limit control only, set K−32768 (or H8000) for the lower limit S1.
To perform lower limit control only, set K32767 (or H7FFF) for the upper limit S2.
Flag conditions
・Error flag (R9007): Turns on and stays on when:
・Error flag (R9008): Turns on for an instant when:
− The area specified using the index modifier exceeds the limit.
− S1 > S2.
・= flag (R900B): Turns on when the result of processing is between the upper and lower limits.
