6.1 Comparison Operation Instructions
BIN 16-bit data band comparisons
ZCP(P)
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) is
compared with the lower limit value (S1) and upper limit value (S2).
• 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.
Precautions
• Set a value smaller than the upper limit value (S2) as the lower limit value (S1). If the lower limit value (S1) is larger than the
upper limit value (S2), the upper limit value (S2) will be handled as the same value as the lower limit value (S1).
• 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 16 bits)
(S2): Start number of the devices where the upper limit value is stored (BIN 16 bits)
(S3): Head number of device where data for comparison or comparison data is stored (BIN 16-bit)
(D): Head number of device where the comparison results are stored (Bit)
