7.17 Data operation instruction
Bit judgment of 32-bit data
DBON(P)
These instructions check whether (n) bit(s) of binary 32-bit data of the device specified by (s) are on or off, and output the
result to the device specified by (d).
■Descriptions, ranges, and data types
■Applicable devices
*1 T, ST, C cannot be used.
• These instructions check whether (n) bit(s) of binary 32-bit data of the device specified by (s) are on or off, and output the
result to the device specified by (d).
• When the result above is on, these instructions turn (d) on. When the result above is off, these instructions turn (d) off.
• When a constant (K) is specified in the device specified by (s), it is automatically converted into binary.
