The 6ES7142-5AF00-0BL0 is an IO-Link digital output module from the SIMATIC ET 200AL family, delivering 2A per channel through eight individual M12 connectors. Unlike the PROFINET variant (0BA0), this module connects directly to any IO-Link master without requiring an ET 200AL interface module or backplane, making it suitable for standalone distributed output applications. It ships with an IODD file for plug-and-play integration into IO-Link engineering tools.

How does IO-Link deployment differ from the PROFINET variant?

Choose the IO-Link variant for standalone field applications where an IO-Link master port is available and you want to avoid the cost of an ET 200AL interface module. Choose the PROFINET variant when building multi-module ET 200AL stations with a shared backplane.

What does the temperature derating mean for high-temperature installations?

Each channel delivers the full 2A at ambient temperatures up to 45C. Above 45C, sustained per-channel current must be limited to 1A at the maximum operating temperature of 55C. For hot environments, either derate the load or spread high-current actuators across channels to keep individual channel currents within the derated limit.

Frequently Asked Questions

What is an IODD file and do I need one?

An IODD (IO Device Description) file contains the device identity, parameters, and diagnostic information for the IO-Link module. It is loaded into the IO-Link master engineering tool to recognize and configure the 6ES7142-5AF00-0BL0. Siemens provides the IODD file on the product support page. Most IO-Link masters can also read basic device identity without the IODD for initial commissioning.

Can I mix IO-Link and PROFINET modules in the same installation?

Yes. The 6ES7142-5AF00-0BL0 connects to any standard IO-Link master port, which in turn connects to a higher-level fieldbus (PROFINET, EtherNet/IP, etc.). This allows IO-Link output modules to coexist with PROFINET I/O on the same machine network, with the IO-Link master acting as the protocol bridge.
