I have 1 24xDI fail safe card (326-1BK02-0AB0). When i powerup the panel everything is OK and i don't have any fault on the CPU/IO card/ET-200. Even i can read few inputs coming to this card with their IX.X address. Now as soon as i turn on the powersupply in the field some other inputs goes on and the red light SF of this card glows and same is reflected on the CPU as ExtF. In the diagnostic it shows that several channels have been passivated. When i check the voltages on all those inputs goes high, and found to be 22.5V which is ok for me. But i can't understand what are the possible reason of the channel passivation. What exactly card senses to know if the DI isn't healthy. Also i would like to know if the channel passivation is the internal feature of the card or the application software may have some logic to generate this fault. I would highly appreciate if someone could really help me out with this problem. Diagnostic message of CPU Event 4 of 31: Event ID 16# 79E3 F-I/O input channel passivated Channel 2 Channel 3 Channel 6 Channel 7 Channel 8 Channel 9 Channel 10 Logical base address: 64 External error, Incoming event 03:29:36.119 PM 08/12/2014 Diagnostic message of Card Event 1 of 1: Event ID 16# F580:0D01 Internal error in the read circuit / test circuit (channel number 2 channel number 3 channel number 6 channel number 7 channel number 8 channel number 9 channel number 10 ) Internal error, Incoming event Best Regards, Waqas Ahmed

So we need to know what settings you use and how things are connected to the module. you can read more in the following link, you learn how to setup and wire the card, maybe you can find the problem on your own.

During passivation theinput in the program will be "0". Please have a look into the diagnaostic buffer of the module itself, there you can find the cause for the passivation. Regards
