The interface module:
Can be used as DP slave on PROFIBUS DP
•
Links the ET 200MP distributed I/O system with the DP master.
•
Exchanges data with the I/O modules via the backplane bus.
•
The I/O modules form the interface between the controller and the
process. The controller detects the current process state via the
connected sensors and actuators, and triggers the corresponding
reactions. I/O modules are divided into the following module types:
Digital input (DI)
•
Digital output (DQ)
•
Digital input/Digital output (DIQ)
•
Analog input (AI)
•
Analog output (AQ)
•
Analog input/analog output (AIQ)
•
Technology module (TM)
•
Communication module (CM)
•
Communication processor (CP)
•
A U connector is included in the scope of delivery for each I/O module.
The modules of the S7-1500 automation system/ ET 200MP
distributed I/O system are connected using the U connector. The U
connector provides the mechanical and electrical connection between
the modules.
The U connector is included in the scope of delivery of all modules
(exceptions: CPU, interface module) and can be ordered as a spare
part (Page 224).
The purpose of the front connectors is to wire the I/O modules.
The front connectors for technology and analog modules must be
supplemented with a shielding bracket, power supply element, and
shielding clamp. These components are included in the scope of
delivery of the technology and analog modules, and may be ordered
as accessories (Page 224).
The front connectors are available for 35 mm modules with screw
terminals and push-in terminals and for 25 mm modules with push-in
terminals.
The front connectors for 25 mm modules are included in the scope of
delivery of the I/O module.
Four potential bridges and one cable tie are included in the scope of
delivery of the front connectors for 35 mm modules. The front
connectors for 25 mm modules have no potential bridges.
You jumper two terminals with potential bridges.
The potential bridges are included in the scope of delivery of the front
connector, and may be ordered as a spare part (Page 224).
The front connectors for 25 mm modules have no potential bridges.
Therefore, you should also observe the information in the product
manual for the respective analog module.
