Equipment Manual, 11/2022, A5E40898375-AC
Description
The 24 V DC supply voltage is supplied via a 4-pole con­
nection plug that is located at the front of the CPU.
The interface serves to connect to a PROFIBUS network.
In the role as a DP master, the CPU addresses the connec­
ted DP slaves. The CPU cannot assume the role of a DP
slave.
The interface has two ports. In addition to basic
PROFINET functionality, its also supports PROFINET IO RT
(real time) and IRT (isochronous real time).
PROFINET functionality, its also supports PROFINET IO RT
(real time).
• IO controller:
As an IO controller the CPU addresses the connected
IO devices
• I-device:
As an I-device (intelligent IO device) the CPU is
assigned to a higher-level IO controller and is used in
the process as an intelligent pre-processing unit of
sub-processes
Description
The system automatically generates the messages for the
system diagnostics and outputs these messages via a
programming device/PC, HMI device, the web server or
the integrated display. System diagnostics information is
also available when the CPU is in STOP mode.
