The rugged I/O for effortless mounting anywhere

With its high degree of protection IP65/67, particularly compact design, low space requirements and weight, SIMATIC ET 200AL is specially designed for distributed control electronics in tight spaces and involving motion. The SIMATIC ET 200AL devices are quickly and conveniently configured and commissioned using the TIA Portal. The modules can be incorporated in the automation network via PROFINET, PROFIBUS or the integration of ET 200SP. SIMATIC ET 200AL modules stand out with a range of advantages as early as in the engineering phase, but also during assembly and in operation, making them the right choice of distributed I/O for a wide variety of applications.

Overview of system components

Wide range of applications for compact IP65/67 IO system due to M8 and M12 modules

Interface Modules

The ET 200AL is connected to the bus system via the interface module, whereby optionally either a PROFINET or PROFIBUS interface module is available. The interface module exchanges the data between the higher-level controller and the I/O modules.

Integration of ET 200SP:
The ET 200AL IO modules can easily be integrated into a ET 200SP configuration, in this case data is exchanged between the ET 200AL IO modules and the higher-level controller via the interface module of the ET 200SP.

• 2 independent backplane bus lines with 16 peripheral modules each = 32 modules can be operated

IP65/67 IOs for the ET 200SP IO-System

The ET 200AL I/O modules are integrated in ET 200SP via the BU-Send and BA-Send 1xFC modules. Data exchange between the ET 200AL I/O modules and the higher-level controller takes place via the ET 200SP interface module.

The connecting cable for the ET 200AL I/O modules is connected to the BusAdapter of the ET 200SP station.
The BusAdapter is simply inserted on the BaseUnit and secured with a screw.


IO Modules

I/O modules are the interface between the SIMATIC ET 200AL and the process:

  • Digital and analog modules provide precisely the inputs/outputs that are required for the respective task

  • Thanks to freely parameterizable hybrid modules with integrated counting function, the ET 200AL thus offers maximum flexibility in many areas of application.

Two power supplies, 1L+ and 2L+ (each 4 A), are available. They are used by the I/O module and looped through to an additional I/O module.

Communication Modules

The CM IO-Link communication module enables data exchange with up to 4 IO-Link devices. With the IO-Link specification V1.1, the current device and master parameters can be automatically transferred to the IO-Link device in the event of a device replacement – without additional application effort.
The 30 mm wide I/O modules are especially suitable for use in extremely confined spaces, have settable parameters and diagnostic functions and can thus be adapted flexibly to the respective process requirements.
