Siemens appendix Resetting the memory of Simotion D410, Data deleted by memory reset

Commissioning (software) 4.12 Deleting data

4.12.2Resetting the memory of SIMOTION D410

Introduction

A memory reset deletes all data from RAM on the SIMOTION D410 and non-volatile data in SRAM with the exception of the communication configuration (baud rates, network addresses, etc.). Data on the CompactFlash Card is retained if you reset the memory.

Reset the memory on SIMOTION D410 if

●You want to undo changes made to user data (programs, configuration data, parameter assignments) which you have not backed up by means of the "Copy RAM to ROM" command.

●The RUN/STOP LED is flashing (slow flashing) to indicate that SIMOTION D410 is requesting a memory reset.

●Non-volatile data does not match the project on the CF card and an error is generated (diagnostics buffer entry).

You can reset memory either in offline mode using the DIL switch of SIMOTION D410, or in online mode using SIMOTION SCOUT.

Data deleted by memory reset

The following data is deleted during a memory reset:

●User data (units, configuration data, parameters, task configuration)

●Technology packages

●Retain TO (absolute encoder adjustment)

●Retain variables

Retain variables in the interface or implementation section of a UNIT are declared with

VAR_GLOBAL RETAIN

Note

As a memory reset deletes all absolute encoder data the encoder must be re-adjusted after memory reset.
