Hi

I have a TD320 that appears to have the V table corrupted. I have a backup of the data needed but each time I connect to READ or WRITE the Block V data I get an error RECEIVE TIMEOUT.

All other communication to the PLC seems OK. I can monitor the program and see the currect data stored in the TD320 but I am currently unable to restore this data.

Any ideas what the problem could be?

Regards
Mark

Hi,
did you try to download a "empty" PLProg application and than download again your application?

Best Regards.

Hello

I have not tried this. It is not something I would automatically try. Why would this help?

Yes, this could help, but if it doesn't solve it could be a hardware problem. Please check the TD Special Marker 1 for the hardware issue.

Best regards.

I tried entering an empty program but this made no difference to the problem of writing data to V table.

I have entered the values manually through the data monitor window. One at a time. I have now added an option for the customer to backup/restore to EEPROM on a protected page on the TD, as the machine is sometimes not used for up to 18 months.

Hi,
maybe the TD320 battery needs to replace it. If you want to replace the battery, please contact our repair tecnical support by this follow link:
