A method and an access unit for accessing an industrial communication network are provided. An access unit has first ports connected to the communication network and at least one second port. The access unit is configured to pass data traffic between nodes of the communication network through the access unit in a first operational state of the access unit. The access unit is configured to pass data traffic to a test node via the at least one second port and/or allow test data to be injected into the communication network via the at least one second port in a second operational state of the access unit.

Method and access unit for accessing industrial communication networks

The application relates to a galvanic separating apparatus, including a printed circuit board, the printed circuit board including a first soldering pad, a second soldering pad and a recess, whereby the pads are arranged on a lower side of the printed circuit board thereby defining a clearance and/or creepage distance between the pads, and the recess is arranged between the pads, a primary insulated winding layer connected to the first soldering pad and a second insulated winding layer connected to the second soldering part, whereby the winding layers are arranged on an upper side of the printed circuit board, and an insulating layer, whereby the insulating layer extends from the upper side through the recess and protrudes on the lower side beyond the printed circuit board thereby increasing the clearance and/or creepage distance.
