Hello ZUMA, For me isn't clear which is number of your basic modules? If this is OBA1 - LOGO! basic modules of the series 0BA0 to 0BA2 cannot be expanded. An overview of the expansion modules that can be connected to LOGO! basic modules is available in the LOGO! manual in section 2.1.2., in Entry ID 36051989. Hope this will helps. Best regards, Hristo Mihalev |

As umencho already mentioned: LOGO! base unit 0BA0 - 0BA2 -> not expandable (so here can´t exist extension modules). Do not be confused because of the order numbers of the extension modules. They often end with ...0BA1. All existing extension modules are compatible with LOGO! 0BA6. Maybe these FAQ´s help you to locate what´s wrong: http://support.automation.siemens.com/WW/view/en/14294500/133000 If the LED´s of the EM´s are red, check the power supply and the bus connector. Do not power up the EM´s after the base unit. |
