Hybrid configuration ET 200AL and ET 200SP
You have the possibility to integrate standard and fail-safe I/O modules of the distributed
I/O systems ET 200AL (IP65/IP67) into a configuration of the distributed I/O system ET 200SP
(IP20). Fail-safe and non-fail-safe modules may be combined at will in the ET 200AL
distributed I/O system.
The figure below shows a combination of the modules of the ET 200AL and ET 200SP
distributed I/O systems.
