There are two types of resources. They are called Single resource and Resource group, respectively.

 

A Resource group is a composite resource that consists of several parts that must be ordered separately. A Single resource is the opposite of a resource group. It is not composed, and it is ordered as one single piece.

 

A resource group thus consists of several single resources. A typical example of a resource group might be a contactor with an auxiliary contact block. Another example could be a signal lamp which may consist of a lamp socket, a light bulb and perhaps some mounting details. In the circuit diagram, the signal lamp corresponds to only one single symbol. By entering a single index in the circuit diagram that corresponds to a resource group in the Catalogue, where that resource group contains the various single resources that need to be ordered, you can get a well-specified device list automatically.

 

There is no direct way to convert a single resource to a resource group or the other way around. Instead, the resource type is determined indirectly by whether the resource contains any single resources or not. That in turn is defined in the Resource group detailed view. Please refer to the description of that.

 

Here it can also be mentioned that there are alternative ways of defining devices consisting of multiple parts. One example of this is so-called “composite indexes”, which are several indexes written in the index attribute. Another example is indexes in help symbols. All these concepts can also be used in combination with each other.
