Safe communication

PROFINET/PROFIsafe communication between AC500-S safety CPUs is supported using
CM589-PNIO(-XC) and/or CM589-PNIO-4(-XC) PROFINET IO device communication modules
together with SM560-S-FD-1(-XC) and/or SM560-S-FD-4(-XC) safety CPUs with F-Device func-
tionality on one side and CM579-PNIO(-XC) with any AC500-S safety CPU on the other side
(Fig. 4 on page 21). SM560-S-FD-1(-XC) and SM560-S-FD-4(-XC) safety CPUs are able to
exchange up to 384 bytes of safety data with F-Hosts (3
ported as well) using PROFINET/PROFIsafe. SM560-S-FD-1(-XC) with F-Device(s) supports
safe communication to maximum one F-Host. SM560-S-FD-4(-XC) with F-Device(s) supports
safe communication to maximum four F- Hosts. Fig. 4 shows that using SM560-S-FD-1 and
SM560-S-FD-4 safety CPUs with additional F-Device functionality one can establish safe CPU
to CPU communication between different control stations on PROFINET/PROFIsafe. SM560-S-
FD-4 safety CPUs can simultaneously communicate not only with 1 IO controller/F-Host
(Master) but with up to 4 IO controllers/F-Hosts (Masters). In addition to SM560-S-FD-1 and
SM560-S-FD-4 safety CPUs, CM589-PNIO and CM589-PNIO-4 PROFINET IO device commu-
nication modules are needed to establish PROFINET connectivity as "black channel", respec-
tively, to 1 or up to 4 PROFINET IO controllers.
