Hello dear engineer. I have an 840c lathe. The cause of error 006F 0400 0300 0700 0100 is it related to LED on the back of the keyboard? Green H1 Yellow H2 Red H3 All 3 LEDs remain bright. ------------------------------------------------------------------------------------------ |

alarm 43 with message 06F have been talking for manay times--it is one of PLC I/O base (inclduing MCP, or you call it keyborad ) defctive or lost power., check which DMP base no LED on? --possible lost power by blown fuses. if all base have LED on, you need check base one by one if you have no ablity to check call your local services

You found problems? if not you need response. take picture of your PLC I/O base --Siemens call DMP
