Hello, I suspect a missing MMC, or a defective MMC, or a bad formatted MMC, ... Without the need of connecting the PC, you must be able, after a reset (with run/stop switch), to have at least a steady Stop LED. May be this can help also: http://support.automation.siemens.com/WW/view/en/21830698 The CPU is deliverd with a terminator. Do not forget to place the terminator at the end of the configuration (either dorectly after the CPU if no central perihery, or afetr the last module) |
