Area of application
The SIMATIC ET 200AL distributed I/O system is especially well suited for use in tight spaces,
moving applications and for assembly and handling technology. Thanks to its scalable
construction, you have the option to precisely customize its configuration to your on site
needs.
The SIMATIC ET 200AL distributed I/O system features degree of protection IP65/IP67. The I/O
modules are suitable for distributed use indoors on a machine or assembly line.
Setup
The SIMATIC ET 200AL distributed I/O system is made up of the following components:
• Interface modules (PROFINET/PROFIBUS)
• Digital and analog I/O modules
• Communication module
After an interface module you can configure 2 lines (ET-Connection), each with 16 modules.
Alternatively, you can configure a line with 16 I/O modules on the SIMATIC ET 200SP
distributed I/O system with BaseUnit BU-Send and the BusAdapter BA-Send 1xFC.
The ET-Connection backplane bus is designed as a cable. This allows you to create spatial
distances of up to 15 m between the modules.
