Configuration and programming
Overview
You can transfer your Safety Program to the Safety CPU from a PC or using SD card.
DANGER!
If you transfer your safety program to Safety CPU using SD card, you have to make sure that the
inserted SD card contains the correct safety program. You can check this through program identifica-
tion (e.g., CRC) or other measures, such as a unique identifier on the SD card.
NOTICE!
The boot project update on SM560-S is possible only if no boot project is loaded on SM560-S. It is
done to avoid any occasional overwriting of existing valid boot project on SM560-S. To delete the boot
project from SM560-S Safety CPU, one can use, for example, the switch address value 0xFE during
the start of SM560-S, which allows deleting the boot project from the Flash memory of SM560-S. The
boot project is finally deleted after SM560-S powering off/on is executed.
When transferring a safety application program to SD card, you must adhere to the following procedure:
1. Transfer the safety program to the SD card.
2. Perform a program identification – check if SD card and offline (e.g., on PC) safety program CRCs
match.
3. Attach an appropriate label to the SD card.
The procedure outlined must be ensured through organizational measures.
For safety applications developed with AC500-S, CoDeSys visualisations using CoDeSys Safety V2.3 are
allowed for displaying purposes only.
DANGER!
Changing values via controls (e.g., "Write values") would cause the SM560-S Safety CPU to switch to
a DEBUG RUN mode, which is non-safe.
In case of an activation of DEBUG RUN (Non-safety) mode on SM560-S Safety CPU, the responsi-
bility for safe process operation lies entirely with the organisation and person responsible for the acti-
vation of DEBUG RUN (Non-safety) mode.
