Checking The Bit Status In 32-Bit Binary Data - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

Checking the bit status in 32-bit binary data

DBON(P)
RnPCPU
RnCPU RnENCPU
(Process)
• The RnCPU and RnENCPU with firmware version "17" or later support these instructions. (Use an engineering tool with version "1.020W" or later.)
These instructions check whether (n) bit(s) of the specified device are on or off, and stores the result in the device specified by
(d).
