  • the modules are connected to a control bus, for example a fieldbus.
  • a control bus for example a fieldbus.
  • each individual module requires an address and each module must be able to decode the signals on the control bus.
  • a harsh industrial environment with dust atmosphere and / or water due to the large number of line connections installation in a control cabinet is necessary because otherwise each plug connection would have to be sealed and the cable insulation would have to meet the special requirements. This is structurally complex and therefore expensive.
