2.8 Exchange of modules
SM560-S Safety CPU automatically detects an exchange of Safety I/O modules during the system start-up.
The overall system (SM560-S Safety CPU and PROFIsafe features of unique addresses for Safety devices
[3]) provides a mechanism to automatically ensure that exchanged safety modules are operated with correct
parameters and incompatible module types are rejected. No unsafe state is possible if wrong Safety I/O
module type is put on the given terminal unit TU582-S.
2.9 AC500-S restart behaviour
When SM560-S Safety CPU is restarted using powering off/on, the previously saved error information is lost.
The Safety I/O modules receive their parameter sets each time during system start-up. SM560-S is able to
reintegrate Safety I/O modules using PROFIsafe start-up behaviour [3]. If your process does not allow an
automatic start-up after powering off/on, you must program a restart protection in the safety program. The
safety process data outputs must be blocked until manually acknowledged. These safety outputs must not
be enabled until it is safe to do so and faults were corrected.
2.10 Replacing AC500-S Safety PLC components
When replacing software components on your programming device or PC with a newer version, you must
observe the notes regarding upward and downward compatibility in the documentation and readme files for
these products.
Hardware components for AC500-S (Safety CPU and Safety I/Os) are replaced in the same way as in a
standard AC500 automation system.
2.11 Environmentally friendly disposal
All AC500-S safety components from ABB are designed with a minimal environment pollution effect. To
enable environmentally friendly disposal of AC500-S safety components, they can be partially disassembled
to separate various components from each other. Disposal of those materials shall be done in accordance
with applicable national and international laws.
