The ST LEDon the XN-312 gateway will show the CANopen status for this bus module.The field bus' status will be indicated as specified in CiA303. The connectorsare three-pin sockets and are internally connected in parallel as an input andan outgoer. Accordingly, two three-pin plugs are included with each gateway.Figure 3: The configuration of the terminal sockets at the gatewaya LED ST red/greenb X1 field bus connection 1c X2 field bus connection 2Table 1: What the signals from the ST diagnostic LED for the CANopen field bus interfacemean; for a more detailed explanation of each status Table , page 45.→ For information on the I/O slice modules' input and output datavolumes, please refer to the appendix in manual "XN300 slicemodules", MN050002-EN".ST LED Status CANopen status MeaningGreen Continuouslight greenOPERATIONAL Operation correctFlashing PRE-OPERATIONAL PRE-OPERATIONALFlashingpatternSINGLE FLASHSTOP HALT①③②GW GWCANSTI/OON OFFUSBS1X1HLGHLGX2ADDRBRST
