The devices that can be used
with the D+ command are circled.
The No. of steps of the D+ command is indicated.
This is a No. of steps required for the store in the controller.
In programming with MELSEC PLC development tool (GX Developer),
the displayed No. of steps may be different from this No. of steps.
Description such as "4/5" indicates that the No. of steps is different
depending on the designation device. For the 32-bit command, two
steps are required for the constant. In the example for the D+ command,
if S2 is the word device, the No. of steps will be 4 steps, and if S2 is the
constant, the No. of steps will be 5 steps.
