Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is
stored in D8067.
• When any device number other than the head device number of a sector of extension file registers is set to
(error code: K6706)
• When a memory cassette is not connected (error code: K6771)
• When the protect switch of the memory cassette is set to ON (error code: K6770)
• When the collation result after data writing is "mismatch" due to omission of initialization or for another
reason (error code: K6770)
When this error occurs, the current values (data) of extension registers (R) may be lost. To avoid the data
loss, back up the data of extension registers (R) in advance using the following procedure:
1) Set the PLC mode to STOP.
2) Create a new project in GX Developer.
This step is not necessary if it is alright to overwrite the current project.
3) Read the contents of extension registers (R) to GX Developer.
[1]Select “Online”
→
“Read from PLC..." to
display the “Read from PLC” window.
[2]Click “Parameter” and “Device data” to
put a check mark to each of them.
[3]Click [Execute] button to execute reading.
[4]When reading is completed, save the
project.
4) Change the current program inside the PLC to
the program shown in “1. Cautions on writing
data to a memory cassette” in “Cautions” on
the previous page.
*1. In some versions of GX Developer, "FX3UC" is
offered as the PLC type.
5) To the PLC, write the data which was temporarily withdrawn to GX Developer.
[1]Select “Online”
→
“Write to PLC...” to
display the “Write to PLC” window.
[2]Click “Parameter” and “MAIN” to put a
check mark to each of them.
[3]Click [Execute] button to execute writing.
*2. In some versions of GX Developer, "FX3UC" is
offered as the PLC type.
6) Change the PLC mode from STOP to RUN, execute the program, and store the data to extension file
registers inside the memory cassette.
