PROGRAMMING
* 1 The following is a processing example for error completion.
From the QJ71MB91 buffer memory (address: 0C18
H
to 0C19
H
), the programmable controller CPU
obtains data such as an error code identified at the time of automatic communication parameter
setting.
(b) Program example for data transfer between QJ71MB91 and programmable
controller CPU
The program example is shown below.
When data transfer between the QJ71MB91 and programmable controller CPU is
set in the Auto refresh setting of GX Configurator-MB, this program is not
required.
Figure 9.12 Program example for error completion of automatic communication parameters
Figure 9.13 Program example for data transfer between QJ71MB91 and programmable controller CPU
Data such as an error
code are fetched into
programmable
controller CPU
devices.
Processing for error
completion
Data to be stored in the programmable controller CPU are as follows:
