Hi all! I'm working on a 414H system in which the slave CPU went into stop mode itself while the switch was at run position even when the master did not try to make a switch. IFM2F LEDs on both CPUs are red and there is a Redundancy fault as well. INTF LEDs on CP modules connencted with the slave are red and they are at stop as well (their switches are at run state). The Synchronous Submodule2 of master has an LED of "Link OK" but it is not on. I replaced it with different submodules (which are working properly on slave or other CPU) but they are not turning on. In hardware dignostics it says the submodule is ok but OB83 is not generating an interrupt. But OB83 is present in the program. My first thought is that the slot is not working. But I am really not sure. It's just my hypothesis. [ Please read this conference about the same system for a context. /tf/WW/en/Posts/93344#top My colleague created this thread last month because all the slave LEDs started blinking. He changed the CPU. And now this happened. I noticed there was no OB84. So I put it in the program. ] I really need help on this issue. Thanks. |

You can interchange the CPUs. |
