Description
All CPUs of the SIMATIC S7-1500 product series fea-
ture a display with plain text information. The display
provides information on order numbers, firmware ver-
sion and serial numbers of all connected modules. In
addition, you can set the IP address of the CPU and
make additional network settings. The display shows
error messages directly as plain text.
The 24 V DC supply voltage is fed via a 4-pin plug
located on the front of the CPU.
The interface is used for connecting to a PROFIBUS
network.
In the role as a DP master, the CPU responds to the
connected DP slaves. It is not possible for the CPU to
take the role of a DP slave.
The interface has two ports. In addition to basic
PROFINET functionality, it also supports PROFINET IO
RT (real time) and IRT (isochronous real time).
The interface has one port. In addition to basic
PROFINET functionality, it also supports PROFINET IO
RT (real time).
The interface is used to:
Link development tools for C/C++ applications
•
Connect the TIA portal to the development of
•
STEP 7 applications
Communicate to the "outside world" from C/C++
•
Runtime
Communicate internally between C/C++ and CPU
•
Runtime (via virtual network)
IO controller:
•
As an IO controller, the CPU addresses the con-
nected IO devices
I-device
•
As an I-device (intelligent IO device), the CPU is
assigned to a higher-level IO controller and is used
as an intelligent pre-processing unit for subroutines
