A0XXXXYYh
Writing an object library
Writes the value of an object library
that can be written when the object
library is set as follows: Ins ID is set
to XXXX and Attr ID is set to YY.
An error code is returned if an
object library that cannot be read is
specified.
Set the write value for the object
library. (Note)
Set the upper 16 bits. (Note)
B0XX0000h
Variable mapping instruction code
Changes the reference object of

variable mapping for the 1st Output
data (Instance 150).
The characters XX in the instruction
code indicate the object to be
changed. Refer to section 6.2.4 (2)
for details.
