Interface

Interfaces defines the Fieldbus cards under IO-Devices of IO configuration in System Manager.

A Fieldbus card can have more than one channel, e.g 2xLight Bus in one card. These 2 channels will be treated as 2 cards in System Manager. In this case, the Name of the Fieldbus can be the same, but the ChannelNo has to be different. As the XML file is imported to generate a System Manager, 2 cards with the name of Name_ChannelNo will be created in System Manager. For Instance, an interface Name= FB, ChannelNo=1 in a XML file, will correspond an IO-Device called “FB_1”.

As observed in System Manager, the Inputs/Outputs of a Fieldbus card can directly linked with PLC variables. The information can be also included in the XML file, as described in the next section.

Box es defines the Bus couplers, which are connected with a Fieldbus card.
