This mode makes it possible tokeep addressing an unchanged full configuration on the field bus sideeven when there is a reduced assembly on the gateway's module side.• Full configurationConfigured maximum setup for the XN300 gateway. This full configura-tion is used to define the addresses that should be used to communi-cate with the individual XN300 slice modules independently of whichXN300 slice modules are actually physically connected to the XN300gateway.• Reduced assemblyThe term "reduced assembly" refers to a permissible subset of the fullconfiguration. In special cases, a reduced assembly may actually be thesame as the full configuration.• Actual configurationThe XN300 slice modules that are physically present and currently beingused with the gateway.• Target configurationThe target configuration is the configuration for the XN300 slice moduleson the system bus that is read by the XN300 gateway and stored in itsmemory when the gateway is switched on with DIP switch 9 = "OFF."8.2 Reason why this mode was implementedThe "station variants" operating mode enables users – and OEM users in par-ticular – to use a variety of increasingly expanding XN300 system configura-tions with the XN-312-GW-CAN gateway without having to make changes tothe corresponding user program.To get started, the user needs to create a PLC program with an XN300 gate-way as a CANopen node. This XN300 gateway needs to be created with thedesired full configuration with all XN300 slice modules in the program.Station variantsFull configuration Reduced assembly
