Reading an object library
Reads the value of an object library
that can be read 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.
The read value of the requested object
library is stored. (Note)
The upper 16 bits of the value is
stored. (Note)
Note.
If the size of an object to be read is smaller than 32 bits, 0 is stored in the remaining areas.

execution completion
(Status DO 10, bit 1)
Respond code
Set a writing instruction code (refer to (2) in this section) in Instruction code, set the data to be written
(data to be executed) in Writing data in hexadecimal, and turn on Instruction code execution demand
(Control DI 10, bit 1).
Turning on Instruction code execution demand (Control DI 10, bit 1) writes the data set with Writing data
to the item corresponding to the writing instruction code. After the writing is completed, Instruction code
execution completion (Status DO 10, bit 1) turns on.
If an instruction code out of the specifications is set in Instruction code, an error code (_ _ 1 _) is set in
Respond code.
Turn off Instruction code execution demand (Control DI 10, bit 1) after Instruction code execution
completion (Status DO 10, bit 1) has turned on.
Until Instruction code execution completion turns on after Instruction code execution demand is turned
on, do not change the values set in Instruction code and Writing data. Turn off Instruction code execution
demand while Instruction code execution completion is on.
