Safety Function And Fault Reaction - ABB AC500-S Safety User Manual

Fig. 4: Exemplary setup for safe CPU to CPU communication between various safety CPUs (SM560-S / SM560-S-
FD-1 / SM560-S-FD-4)
The following communication requirements shall be fulfilled for using AC500-S safety PLC:
● Safety data cannot be transferred over public networks, e.g., internet. If safety data is trans-
ferred across company/factory networks, ensure that sufficient protection is provided against
manipulation (firewall or router for network separation).
● Equipment connected to communication devices shall feature safe electrical isolation.

Safety function and fault reaction

The main safety function of AC500-S safety PLC is to read safety digital and analog inputs to
control the safety digital outputs by the safety logic module safety CPU according to a user-
defined IEC 61131 application program and configuration.

NOTICE!
You can use AC500-S safety I/O modules and SM560-S-FD-1 / SM560-S-FD-4
rd
safety CPUs with 3 party F-Hosts on PROFINET. Download and install valid
ABB GSDML files in your 3
www.abb.com/plc.
After this, you can configure and use these AC500-S modules with 3
Host. Contact ABB technical support on how to obtain F_iPar_CRC values of
AC500-S safety I/O modules for 3
Validate that all iParameters (input delay, channel configuration, etc.) for all
AC500-S safety I/Os and other F-Devices are correct with a given F_iPar_CRC
value using appropriate functional validation tests or verification procedure for
those parameters Ä Chapter 6.5 "Verification procedure for safe iParameter
setting in AC500-S safety I/Os" on page 332.
Default F_iPar_CRC values used in GSDML files for AC500-S safety I/O mod-
ules do not correspond to default iParameter configurations for AC500-S safety
I/O modules and have to be re-calculated in the engineering tools before their
usage. It was done to avoid unintended use of AC500-S safety I/O with 3
F-Hosts.
