IP-Link Error

On IP-Link error

Fieldbus Error

On failure of the superior fieldbus, the outputs of the Extension Box Modules behave in the same way like the Coupler Box they are connected to.

The behavior of Coupler Box and Compact Box Modules is fieldbus specific (see Fieldbus Box documentation for the superior fieldbus) and depends on the parameterizing.
