n Switch address value 0xFD during the start of SM560-S allows deleting user data from the Flash memory
of SM560-S. The user data are finally deleted after SM560-S powering off/on is executed. This can be
needed if user data are corrupt and could lead to a SAFE STOP state of SM560-S. SM560-S goes to
SAFE STOP state after start-up and 0xFD command execution.
n Switch address value 0xFC during the start of SM560-S allows deleting all SM560-S data, which
includes, in addition to boot project and user data, also SM560-S password and defined power dip value
from the Flash memory. This means that SM560-S will be brought to its original state. The data are finally
deleted after SM560-S powering off/on is executed. SM560-S goes to SAFE STOP state after start-up
and 0xFC command execution.
The switch address value range 0xF0 ... 0xFB is reserved for future internal system functions.
NOTICE!
Usage of switch address values from the system range 0xF0 ... 0xFF can lead to the loss of important
user information in the Flash memory of SM560-S, e.g., boot project, user data, password or power
dip value can be lost. Therefore, it is important that users pay a special attention during the change of
switch address position on SM560-S Safety CPU.
NOTICE!
Despite the fact that SF_SM5XX_OWN_ADR function is a safety POU, the hardware switch address
value is a non-safety value and needs additional measures to satisfy functional safety requirements.
3.1.2.6 Firmware, boot code and boot project update using SD card
The firmware, boot code and boot project update can be executed using standard AC500 SD card functions
from PM5xx CPU. One has to do appropriate changes in the SDCARD.INI file on SD card, as it is described
in AC500 User Documentation [4]. The directories and slot number, on which SM560-S Safety CPU is used,
shall be taken into account.
NOTICE!
From the AC500 platform definition, SM560-S Safety CPU is one of the communication modules.
Thus, definitions for SD card handling in AC500 User Documentation [4] are also valid for SM560-S
Safety CPU.
If FunctionOfCard=2 is going to be used for SM560-S Safety CPU, then a proper entry in SDCARD.INI
file on SD card shall be made, e.g.,
[SM560]
TYPE=4
VERSION=1_0_0
If boot project update shall be carried out using SD card, then proper files SM560_<x1>.prg and
SM560_<x1>.chk (x value is dependent on the slot number 1 ... 4 on which SM560-S is located) shall
be copied to UserData\PM5xx\UserPrg\ directory on the SD card (
for more details).
