Comparing 32-Bit Binary Block Data - Mitsubishi MELSEC iQ-F FX5 series Programming Manual

Comparing 32-bit binary block data

DBKCMP(P)(_U)
These instructions perform a comparison operation between the (n) point(s) of 32-bit binary data starting from the device
specified by (s1) and the (n) point(s) of 32-bit binary data starting from the device specified by (s2), and store the operation
result in the device specified by (d).

Processing details
• These instructions perform a comparison operation between (n) point(s) of 32-bit binary data starting from the device
specified by (s1) and (n) point(s) of 32-bit binary data starting from the device specified by (s2), and store the comparison
result in (n) point(s) of data starting from the device specified by (d).
• The relevant (n) point(s) of data starting from the device specified by (d) are turned ON when the comparison conditions are
met and turned OFF when the comparison conditions are not met.
