Non-volatile data
Non-volatile data is used with the objective of retaining user- and system-relevant data when
SIMOTION D410 is in de-energized state. You will find information about the area that can
be used for non-volatile data in the
SIMOTION SCOUT
Configuration Manual.
Non-volatile data available in SIMOTION devices:
Table 2- 1 Content of non-volatile data
Non-volatile data Content
Kernel data
• Last operating state
• IP parameters (IP address, subnet mask, router address)
• DP parameters (PROFIBUS DP address, baud rate)
• Diagnostics buffer
Retain variables
• Variables in the interface or implementation section of a unit declared
with VAR_GLOBAL RETAIN
• Global device variables set with the "RETAIN" attribute
Retain TO Absolute encoder offset
DCC blocks SAV blocks and user-defined blocks with retain behavior.
("SAV = SAVE", blocks for the non-volatile data backup)
Note
DCC SIMOTION blocks with retain behavior act like retain variables in terms of copying RAM
to ROM, performing a memory reset, downloading, backing up non-volatile SIMOTION data
(_savePersistentMemoryData), and backing up data such as retain variables.
With DCC SINAMICS blocks, data are only backed up using FRAM, i.e. not
_savePersistentMemoryData.
For additional details, please refer to the
DCC Programming
Programming Manual.
The SIMOTION D410 backed-up data have the following features:
