The mounting rail is the rack of the S7-1500 automation system. You
can use the entire length of the mounting rail (marginless assembly).
The mounting rails can be ordered as Accessories/spare parts
(Page 253) accessories.
The set of screws is threaded into the mounting rail's T-profile groove,
and is required for grounding the mounting rail.
The set of screws is contained in the scope of delivery of the mounting
rails in the standard lengths (160 to 830 mm) and can be ordered as
Accessories/spare parts (Page 253).
The CPU executes the user program. The integrated system power
supply of the CPU supplies the modules used via the backplane bus.
Further features and functions of the CPU:
Communication via Ethernet
•
Communication via PROFIBUS / PROFINET
•
HMI communication
•
Integrated web server
•
OPC UA server
•
Integrated technology (e.g. motion control functions, trace func-
•
tionality)
Integrated system diagnostics
•
Integrated protection functions (access, know-how and copy pro-
•
tection)
Safety mode (when using fail-safe CPUs)
•
The interface module:
Is used as an IO device on PROFINET IO
•
Links the ET 200MP distributed I/O system with the IO controller.
•
Exchanges data with the I/O modules via the backplane bus.
