■DBK-
• This instruction subtracts BIN 32-bit data stored in the n-point devices starting from the device specified by (S2) or a
constant from BIN 32-bit data stored in n-point devices starting from the device specified by (S1), and then stores the
operation result into the nth device specified by (D) and up.

• Block subtraction is performed in 32-bit units.
• The constant in the device specified by (S2) can be between -2147483648 to 2147483647 (BIN 32-bit data).
• If the value specified by n is 0, the instruction will be not processed.
• Specify (D) out of the range of n-point devices starting from the device specified by (S1) and (S2). However, (S1) and (S2)
can specify the same device.

Operation error
• In any of the following cases, an operation error occurs, the error flag (SM0) turns on, and an error code is stored into SD0.

4100
A negative value is specified for n.
4101
The points specified in n exceed those of the corresponding device specified
in (S1), (S2), or (D).
The ranges of devices starting from the one specified in (S1) and (D) overlap
by n points. (except when the same device is specified in (S1) and (D)).
The ranges of devices starting from the one specified in (S2) and (D) overlap
by n points. (except when the same device is specified in (S2) and (D)).
