BIN 32-bit block data comparisons
DBKCMP(P)
Processing details
• This instruction compares BIN 32-bit data stored in n-point devices starting from the device specified by (S1) with BIN 32-bit
data stored in n-point devices starting from the device specified by a constant and (S2) and then stores the result into the
nth device specified by (D) and up.
nth device specified by (D) and up.
• The comparison operation is conducted in 32-bit units.
• The constant in the device specified by (S1) can be between -2147483648 and 2147483647 (BIN 32-bit data).
• The constant in the device specified by (S1) can be between -2147483648 and 2147483647 (BIN 32-bit data).
• Specify (D) out of the range of n-point devices starting from the device specified by (S1) and (S2).
• QnU(D)(H)CPU, QnUDE(H)CPU: the serial number (first five digits) is "10102" or later
• Q00UJCPU, Q00UCPU, Q01UCPU, QnUDVCPU: Supported
• Q00UJCPU, Q00UCPU, Q01UCPU, QnUDVCPU: Supported
(S1): Data to be compared or head number of the devices where the data to be compared are stored (BIN 32 bits)
(S2): Head number of the devices where the comparison data are stored (BIN 32 bits)
(D): Head number of the devices where the comparison operation result will be stored (bits)
n:
(S2): Head number of the devices where the comparison data are stored (BIN 32 bits)
(D): Head number of the devices where the comparison operation result will be stored (bits)
n:
Number of comparison data blocks (BIN 16 bits)

• If the comparison condition has been met, the corresponding devices specified by (D) will be turned on.
• If the comparison condition has not been met, the device designated by (D) will be turned OFF.
• If the comparison condition has not been met, the device designated by (D) will be turned OFF.
