WTOB (FNC141)

Devices storing the combination source data may be equivalent to devices storing the combined data.

After combination, however, the high-order byte (8 bits) of the combination source data stored in the devices used for

the combination destination data is erased and overwritten with the data acquired by combining the high-order byte (8

Because these combination source devices are

also used for the combination destination, "ABH"

and "CDH" are erased and overwritten.

An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in

• When the combination source devices

• When the combined data destination devices

code: K6706)

When "n" is an odd number, the number of a rounded up value decides the numer of devices. (error code: K6706)

Program example

In the program shown below, the low-order byte (8 bits) data stored in D20 to D25 is combined, and stored in D10 to

The high-order bytes is ignored.

Separates consecutive 16-bit data in byte units (8 bits).

The high-order bytes is ignored.
