Engineering interface of the MOVI-PLC
®
advanced DH.41B controller
The engineering access to the MOVI-PLC
®
advanced
DH.41B controller is realized via
the Ethernet 2 interface (connector X37). Engineering access to the MOVI-PLC
®
advanced
DHF41B controller is also possible via PROFIBUS (connector X30P) and to
the MOVI-PLC
®
advanced
DHR41B controller via Ethernet (connector X30-1/2).
4.10 Shielding and routing bus cables
Only use shielded cables and connection elements that also meet the requirements of
category 5, class 2 in compliance with IEC 11801 edition 2.0.
Correct shielding of the bus cable attenuates electrical interference that may occur in
industrial environments. The following measures ensure the best possible shielding:
• Manually tighten the mounting screws on the connectors, modules, and equipotential
bonding conductors.
• Use only connectors with a metal housing or a metallized housing.
• Connect the shielding in the connector over a wide surface area.
• Apply the shielding of the bus line on both ends.
• Route signal and bus cables in separate cable ducts. Do not route them parallel to
power cables (motor leads).
• Use metallic, grounded cable racks in industrial environments.
• Route the signal cable and the corresponding equipotential bonding close to each
other using the shortest possible route.
• Avoid using plug connectors to extend bus cables.
• Route the bus cables closely along existing grounding surfaces.

STOP!
In case of fluctuations in the earth potential, a compensating current may flow via the
bilaterally connected shield that is also connected to the protective earth (PE). Make
sure you supply adequate equipotential bonding according in accordance with relevant
VDE regulations in such a case.
