2.1.1 System

The AC500-S Safety PLC is an integrated part of AC500 platform with a real common Look & Feel engi-
neering approach. Due to a tight integration in AC500 PLC platform, the generic AC500 system characteris-
tics (mechanics, programming, configuration etc.) are also valid for AC500-S Safety modules.
All non-safety AC500 modules are considered to be interference-free modules for AC500-S Safety PLC. In
contrast to Safety modules, interference-free modules are not used to perform Safety Functions. A fault in
one of these modules does not influence the execution of the Safety Functions in a negative way.
The term Integrated Safety applied for AC500-S Safety PLC and AC500 platform means:
One PROFINET IO fieldbus is used for Safety and Non-safety communication.
n
n The same engineering environment with real Look & Feel is used for both Safety and Non-safety pro-
gramming.
n The same hardware and wiring Look & Feel is used within Safety and Non-safety modules.
n The same diagnostics concept is used for Safety and Non-safety modules.

AC500 covers all common communications standards, such as Ethernet, EtherCAT, PROFINET IO,
PROFIBUS DP, CANopen, DeviceNet, Modbus TCP, Modbus serial, Serial, ABB CS31 and PROFIsafe
via PROFINET. Combinable to form optimally scaled network nodes, ABB's AC500 is suitable for both
small-scale applications and large-scale industrial systems.

SM560-S Safety CPU certified up to SIL3 (IEC 62061, IEC 61508 ed. 2) and PL e (ISO 13849). An array
of features such as system diagnostics provided via LEDs and onboard display of standard CPUs pro-
vides the added diagnostic concept required for integrated safety.

ABB's complete AC500 range of CPUs, from the PM573 to the PM592, can be used with Safety CPU to
create customized solutions – even for the most challenging requirements. The programming of safety
and non-safety applications is offered via a standard PLC interface.
