Since RTE 34.15.3, the possibility of DUMP/RESTORE of all retentive memory has been added.

DUMP Procedure

NOTE: Deprecated. If possible, use RQ_RETMEM_SAVE_ONCE.

•Create the file RQ_RETMEM_SAVE and add it to the /DUMP/ directory present in the CF/SD.

NOTE: The file must be non-empty (just enter a character) and without an extension.

•Turn on the control and wait for the register write operation. During this operation the LED sequence will be: Display 05, L7 ON, L8 OFF --> Display 50, L7 OFF, L8 ON --> Display 00, L7 OFF, L8 OFF

•If the operation has a successful result, the file /DUMP/RETMEM_DUMP_yy_mo_dd_hh_mi_ss.STB will be created, containing the retentive memory copy of the control. The control will remain stationary in this condition, showing the sequence: Display 55, L7 OFF, L8 ON --> Display 51, L7 ON, L8 OFF

NOTE: The file name is referenced to the date and time of its creation (e.g., RETMEM_DUMP_17_07_21_11_05_19.STB indicates that it was created on July 21, 2017 at 11:05:19 a.m.).

NOTE: If you have a lost memory event, the file RETMEM_DUMP_yy_mo_dd_hh_mi_ss.STB.LS is generated instead from which you can trace the previous condition.

•Turn off the control, remove the flash, and use a CF/SD reader to save the newly created file. Finally, remove the /DUMP/RQ_RETMEM_SAVE file (otherwise the procedure would be repeated).

Single DUMP procedure

•Load a non-empty file named RQ_RETMEM_SAVE_ONCE into /DUMP/

•Turn the control off and on again

•Wait for the end of the save operation

•Turn the control off and on again

NOTE for internal use only: the RETMEM.EXE program is available to do analysis of the file contents.

RESTORE procedure

NOTE: Deprecated. If possible, use RQ_RETMEM_RESTORE_ONCE.

•Create the non-empty file RQ_RETMEM_RESTORE and add it to the /DUMP/ directory present in the CF/SD

•Place the RETMEM_DUMP_yy_mo_dd_hh_mi_ss.STB file created by the DUMP procedure in the /DUMP/ directory. Only one of these files should be present in the directory

•Turn on the control and wait for the register write operation. During this operation the LED sequence will be: Display 03, L7 ON, L8 OFF --> Display 30, L7 OFF, L8 ON --> Display 00, L7 OFF, L8 OFF

•If the operation results successfully, the contents of the file will be copied inside the retentive memory. The control will remain stationary in this condition, showing the sequence: Display 33, L7 OFF, L8 ON --> Display 51, L7 ON, L8 OFF

•Turn off the control, remove the flash, and use a CF/SD reader to erase the /DUMP/RQ_RETMEM_RESTORE file (otherwise the procedure would be repeated)

Single RESTORE procedure

•Load into /DUMP/ a non-empty file named RQ_RETMEM_RESTORE_ONCE

•Only one RETMEM_DUMP_yyy_mo_dd_hh_mi_ss.STB file should be present in the /DUMP/ directory

•Turn the control off and on again

•Wait for the end of the requested operation

•Turn the control off and on again
