Please look also to the LED specification for the DI, DO, ... modules: http://support.automation.siemens.com/WW/view/de/86140384 For example at page 893 of this document you find the specification for DI 32x24VDC HF digital input module (6ES7521-1BL00-0AB0), which is essentially the same for all modules. According to that, a green flashing LED indicates, that the module is not configured properly. A reason for that may be, that something with your Hardware-Configuration in the TIA-Portal is wrong. I would recommend to double check whether the modules are configured inthe project (TIA-Portal -> Hardware Configuration), and if so you shoulddownloadagain to the CPU. If you have problems with the download, you may format the memory card before downloading (TIA-Portal -> Online & Diagnostic -> Format Memory Card). |
