I'm Hasan Fahmi, Signalling Engineer from ERL-Maintenance Support SDN BHD. This is regarding my PLC S7-400(part Num: 6ES7417-4HL00-0AB0) which had been installed in 2001. Currently we have some intermittent problem with our CPU S7-400, the standby(slave CPU) getting STOP suddenly with unknown reason. If today we reset the fault on CPU2 by toggle swith (blue toggle) the fault on Traffic Management System(TMS) will cleared and after 5 or 10 hrs later the standby CPU(CPU1 or 2) will stop(with indication Extf, Redf and stop led lit on Slave CPU and the master CPU is run as normal with the Redf led is lit. during night we reset the CPU by toggle blue switch it was cleared. We had replaced new CPU for PLC 2 so far, however the failure still occuring after 5-10 hrs reset. The fault always appeared on the Standby CPU. Those were re-occured since 14 Jan 2019 until yesterday(27 Jan 19). Can admin advise on the said fault and is there any possibility if we have a software tools to download the PLC for further analyse the fault, so it will be easier to find the route cause. Until now we don't have any clue which part was causing the standby CPU to stop. ------------------------------------------------------------------------------------------ |
