3 Commissioning3.1 Take system bus into operationGateway XN-312-GW-CAN 06/16 MN050003-EN www.eaton.eu 393 CommissioningBefore switching on, check whether the power supply for the gateway isconnected correctly. The configuration and installation of the system busmust also have been carried out correctly with all modules connected.Startup takes place in several steps:1. Putting the system bus into operation2. Load and start the PLC program.3.1 Take system bus into operationWhen you replace XN300 slice modules without switching off the powersupply, the XN-312-GW-CAN gateway will carry out a software-controlledRESET.The system bus can be placed into operation with or without a configurationcheck. Accordingly, decide whether the configuration check function on thegateway should be enabled or not (it will be disabled by default).If the type or number of connected modules changes and the configurationcheck function is enabled, you will need to disable the configuration checkfunction and start the gateway with the function disabled. When you do so,the gateway will read the modified target configuration, after which you canre-enable the configuration check function.As an alternative to commissioning the station using the configuration checkbased on the DIP switches on the device, you can have the PLC run the con-figuration check instead. This option is described in detail in the followingchapter ￫ Chapter 8 “Station variants”, page 355. DANGERIf you have already integrated devices and equipment into a sys-tem, block off any parts of the system that are connected to theworking area in order to prevent access. This will ensure that noone is injured if the system behaves unexpectedly, e.g., motorsstart up unexpectedly. DANGERSwitch off the power supply whenever replacing XN300 slicemodules.The XN300 slice modules may be ruined otherwise!
