++++++++++++++++++++++++++++++++++ Hi, My DO (SM322,DO 32x) card on S7-300 CPU is showing SF2 fault (RED LED) on one group of output channel, as indicated in attached picture. Local troubleshooting indicates problem with the DO card. This DO card is having digital outputs to UCP panel for operating my Mainline Pump-A and other parameters. Other two pumps B and C are having inputs from other DO cards (Slot-A108) etc .( please refer attached PDF for schematic.) Problem: 1. My Processor was is showing in stop mode due to this SF2 error on my DO card, and processor is not getting into run mode (attached picture of processor) , can anybody suggest whether i could bypass this faulty card till the time i get corrected DO card, and run my other two pumps. I am not sure whether entire card is considered faulty if one of the four grup of channel is in sf fault? 2. In have tried power reset, however processor is not getting into run mode. Please suggest what could be best option to run the processor at the earliest since my pumps are not running. Can I swap this card with other DO card in rack which is having less imp parameters. Also will my CPU come back to run mode in presence of fault ? Please suggest. Attachments: 1. Error screenshots. 2. Log file/backup file. 3. Schematic file. ...sent from App Attachmentissue.zip (341 Downloads) |

Hi, Please see attached diagnostic buffer with screenshots of memory utilization. Stop LED on processor was continuously blinking today after I removed faulty DO card from system, and re-run the CPU-314 module. Also we are having DO module with no. SIMATIC S7-300 DIGITAL OUTPUT SM 322, 32 DO, 120/230 V AC. (6ES73221FL000) , Could you please suggest alternative compatible DO card for this card, since this card is obsolete and not readily available, Thanks. AttachmentDiagnostic.zip (338 Downloads) |
