Mode of operation

Via PROFINET, PROFIBUS or ET 200SP, a central controller can access the distributed I/O modules of the ET 200AL in the same way as central I/O modules.
Communication is carried out fully automatically between the I/O controller in the central controller and the IM 157-1 or IM 155. Interference-free internal data transfer using shielded cables.

Comprehensive, module-specific diagnostics with plain text messages enables rapid location and elimination of system faults in the shortest possible time. Annoying plant downtimes belong to the past, and availability is significantly increased.

Configuration, parameterization and diagnostics

The ET 200AL is configured and assigned parameters via TIA Portal, STEP 7 or the configuration tool of the controller used.

The IO-Link master is configured using the S7-PCT (Port Configuration Tool).
