BIN 32-bit data band comparisons

• LCPU: The serial number (first five digits) is "16042" or later.

• QnUDVCPU: The serial number (first five digits) is "16043" or later.

(S1): Start number of the devices where the lower limit value is stored (BIN 32 bits)

(S2): Start number of the devices where the upper limit value is stored (BIN 32 bits)

(S3): Head number of device where data for comparison or comparison data is stored (BIN 32-bit)

(D): Head number of devices where the comparison results are stored (Bit)

Internal device

Processing details

• One of (D), (D)+1, and (D)+2 turns on depending on the results (small, within the band, large) after comparison data (S3),

(S3)+1 is compared with the lower limit values (S1), (S1)+1 and the upper limit values (S2), (S2)+1.

• When the contact turns off, "(D) to (D)+2" hold the conditions immediately before the contact turns on and off.

Operation error

• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.

Error details

The range of 3 points from the device specified in (D) exceeds the range of

the corresponding device.

• Set values smaller than the upper limit values (S2), (S2)+1 as the lower limit values (S1), (S1)+1. If the lower limit values

(S1), (S1)+1 are larger than the upper limit values (S2), (S2)+1, the upper limit values (S2), (S2)+1 will be handled as the

same values as the lower limit values (S1), (S1)+1.
