My first question: For an evacuation alarm I use two logo! 12/24RCE (both master, 6ED1 052-1MD08-0BA0 FS:02 FW:V1.82.02 A Ethernet cable between. Each has an emergency button and a horn. If one of the buttons is pressed, the alarm will sound for both. I have this functional. But if the connection is not good (broken, fire), the alarm should also go off at both locations. I tried with 'Ethernet link error', send signals back and forth periodically. So far, only one goes into alarm when the Ethernet cable is disconnected. Someone a working alternative?

Due to an asynchronous pulse generator, this bit is high for 1 second and then low for one second. The receiving LOGO! queries this bit. If the bit remains HIGH (or LOW) for more than 1.5 seconds, communication is disturbed for some reason. Attachment Communication_monitoring_for_two_LOGO!s_0BA8.Standard.zip (292 Downloads)
