Dear Experts, I have siemens S7 315-2 DP/PN PLC and MP 377 HMI. both are connected in the Scalance x 300 (6GK5 308-2FM00-2AA3). and the ET200s submodules are connected with the another scalance switch and all are connected together with fiber optic. My question was my HMI (MP 377) was got faulty so i replaced the same HMI and put the backup in prosave. My HMI not communicating with the PLC and No alarms and indication was showing in the HMI. I know that all hardware are OK and PLC showing BF2(blinking) and SF(steady) are showing. I checked the diagnostic buffer and it was my one et200s was not communicated. 1)Now, I need to know why my HMI not showing any indication or alarms? Also, I checked the IP address it's all are in same series. Also, it is the same backup which was working before. I don't know what is the problem. I attached the file for your reference. My English is bad. I hope you understand. Thank you AttachmentAttached File.zip (1 Downloads) |
