Abstract
The invention relates to a control cabinet monitoring device, comprising a control device which is connected via a field bus to various sensors and/or actuators for monitoring and controlling various control cabinet functions, such as climate control, moisture control and access control. Flexible adaptation possibilities for different applications of control cabinets are offered in that at least one part of the sensors and/or actuators are direct connection sensors and/or direct connection actuators, each having a dedicated bus coupling circuit and being coupled by same to the field bus, and the control device has an initialization unit or can be connected to such a unit, via which the direct connection sensors and/or the direct connection actuators can be initialized before startup and automatically addressed and are subsequently connected via the control device for the exchange of data for operating purposes on the basis of individually allocated addresses.

13. A control cabinet monitoring device, comprising a control device which is connected via a field bus to various sensors and/or actuators for monitoring and controlling various control cabinet functions, such as climate control, moisture control, access control, wherein at least one part of the sensors and or actuators are direct connection sensors and/or direct connection actuators, each having dedicated bus coupling circuit and being coupled by same to the field bus,
the control device comprises an initialization unit or can be connected to such a unit, via which the direct connection sensors and/or the direct connection actuators can be initialized before startup and automatically addressed thereby and are subsequently connected via the control device for the exchange of data for operating purposes on the basis of individually allocated addresses, each of said direct connection sensors and/or direct connection actuators as well as the initialization unit are provided with an enabling stage, at the beginning of the initialization an enabling signal is on merely in the initialization unit, which signal can be recognized at the input side of the first one of said direct connection sensors or direct connection actuators coupled to the field bus, while it cannot be recognized by succeeding direct connection sensors and/or direct connection actuators coupled to the field bus due to not connected enabling stage of said first direct connection sensor and/or direct connection actuator, in this state the initialization of said first direct connection sensor and/or direct connection actuator can be accomplished with allocation of its address and notification of its specific characteristic data stored therein, and subsequent to its initialization and successful application via its enabling stage the enabling signal can be connected to the succeeding direct connection sensor or direct connection actuator, whereupon the initialization of the succeeding and correspondingly the respective further succeeding direct connection sensors and/or direct connection actuators is accomplished successively, and the order of direct connection sensors and/or direct connection actuators can be stored in said control device.

23. A method for initializing a control cabinet monitoring device comprising sensors and/or actuators coupled to a field bus and a control device having an initialization unit, wherein
said sensors and/or actuators are directly coupled to the field bus at least partly as direct coupling sensors and/or direct coupling actuators, at the beginning of the initialization only within the initialization unit an enabling signal and a non-initialization signal are brought into a voltage condition, while enabling signals in said direct connecting sensors and/or direct connecting actuators are not connected, a first one of said direct connecting sensors or direct connecting actuators recognizes the enabling signal of the initialization unit at its input and switches on a terminal resistor, subsequently, initialization data are exchanged between said initialization unit and said first direct connection sensor or direct connection actuator, an address being allocated by said initialization unit to said direct connection sensor or direct connection actuator and specific characteristic data stored therein are notified to the initialization unit, said initialization unit decides whether said first direct connection sensor or direct connection actuator may start normal operation on said field bus and is logged on, if necessary, subsequently, when starting normal operation, said direct connection sensor or direct connection actuator switches on a supply of its sensor or actuator system and connects through the enabling signal to the succeeding direct connection sensor or direct connection actuator and enables the non-initialization signal, while recognizing the presence of at least one direct connection sensor or direct connection actuator by said non-initialization signal remaining at an initial voltage level, in particular ground level, and when detecting the presence of the terminal resistor switches off automatically, and the optionally succeeding direct connection sensors or direct connection actuators on the field bus are successively initialized in this way, respectively, and subsequently initialization is completed, the recognized order of direct connection sensors and/or direct connection actuators connected to the field bus being stored.
