Product overview

2.1

Operating principle

The CPU includes the operating system and executes the user program. The user program
is located on the SIMATIC memory card and is processed in the CPU work memory.
The PROFINET interfaces available on the CPU enable simultaneous communication with
PROFINET devices, PROFINET controllers, HMI devices, programming devices, other
controllers and additional systems. The CPU 1510SP-1 PN supports operation as an IO
controller, I-device or standalone CPU.
With its optional PROFIBUS interface, CM DP, CPU 1510SP-1 PN supports the
configuration of PROFIBUS networks in addition to PROFINET IO. When you use the
interface as a PROFIBUS DP interface, you can configure the CPU 1510SP-1 PN as a DP
master or as an intelligent DP slave (I-slave).
IO controller
CPU 1510SP-1 PN sends and receives data from the connected IO devices within a
PROFINET IO system. You can operate the CPU with up to 64 connected IO devices.
I-device
The "I-device" (intelligent IO device) functionality allows you to exchange data with an IO
controller. CPU 1510SP-1 PN thus fulfills the role of an intelligent distributed pre-processing
unit for sub-processes. The I-device is connected as an IO device to a higher-level IO
controller for this purpose.
Advantages:
● Interference-resistant configuration due to short signal and encoder wiring
● Reduced wiring requirements for transmission of the data via PROFINET
Standalone CPU
You can also use the CPU 1510SP-1 PN in the ET 200SP distributed I/O system as a
"central system" without a higher-level controller.
DP master
To use the ET 200SP as a DP master, you need the CPU and the optional communication
module, CM DP. When used as a DP master, ET 200SP exchanges data with the connected
DP slaves via PROFIBUS DP.
