Fig. 1: Overview on ABB's AC500 family with safety and non-safety modules
1 Non-safety communication module
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.
2 Safety CPU
Safety CPUs certified up to SIL 3 (IEC 61508), SILCL 3 (IEC 62061) and PL e
(ISO 13849-1). An array of features such as system diagnostics provided via LEDs and
onboard display of non-safety CPUs provides the added diagnostic concept required for
integrated safety.
3 Non-safety CPU
ABB's complete AC500 range of non-safety CPUs 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 non-safety PLC interface.
4 Safety I/O module
Safety I/O modules certified up to SIL 3 (IEC 61508), SILCL 3 (IEC 62061) and PL e
(ISO 13849-1). Features such as channel-wise error diagnostics and the flexibility to choose
between channel-wise or module switch-off in case of channel error make working safely
easier.
5 Non-safety I/O module
With ABB's non-safety I/O modules, the complete S500 and S500-eCo I/O module range
can be connected to the non-safety PLC. A wealth of functions in AC500 configurable I/O
modules allows getting the customized and low-priced solutions to optimize industrial appli-
cations.
