7.13 Data Control Instructions 7.13.1 LIMIT, LIMITP, DLIMIT, DLIMITP
7.13 Data Control Instructions
: Lower limit value (minimum output threshold value) (BIN 16/32 bits)
: Upper limit value (maximum output threshold value) (BIN 16/32 bits)
: Input value to be controlled by the upper and lower limit control (BIN 16/32 bits)
: Head number of the devices where the output value controlled by the upper and lower limit control will be stored (BIN 16/32 bits)
Function
LIMIT
(1) Controls the output value to be stored at the device designated by by checking whether the input value (BIN 16 bits)
designated by is within the range of upper and lower limit values specified by and or not.
Output value is controlled in the way shown below:
• When .................................
• When .................................
•When .....
(2) Values in the range from -32768 and 32767 can be designated at , , and .
(3) When control based only on upper limit values is performed, the lower limit value designated at is set at " 32678".
(4) When control based only on lower limit values is performed, the upper limit value designated at is set at "32767".
