Signal status LEDs
The definition of the LED signals of the external I/O extension (SK TU4-IOE-
…) corresponds to that for the
internal I/O - extension SK CU4-IOE. The appropriate details are described in Section 3.4.3.3.
Exception: The signal statuses of the digital inputs and outputs (DI … / DO …) are only visualised with the
M12 version (SK TU4-IOE-M12) (See also Section 3.5.4 "Details of the M12 connections of the
SK TU4-IOE-M12").

Termination resistor, addressing, assignment of functions, broadcast mode
The internal and external I/O extensions have identical functions, insofar as the procedure for configuration,
addressing etc. of the SK TU4-IOE-
… is carried out as for the SK CU4-IOE-…. (For details, see Sections
