ET200S IM 151-3 PN SF and BF led blinking

Hello,

I have problem with Profinet card ET200S 151-3 PN (6ES7151-3AA23-0AB0). The main card does not see the modules, it is visible on the network.

The sequence of flashing LEDs is as follows:

1. SF and BF slow 3 times

2. BF 1 time

3. SF and BF fast 3 times

4. SF 1 time

5. BF fast 5 times

how many modules are inserted to this IM rack, for sure? You have termination module inserted?

From error LEDs it can indicate problem with module at slot 5 or 15 but more informations are required for sure about that number of modules or more racks on network.

28 modules

Hello,

great, this means that termination module isn't problem. I recommend check 5-th or 15-th slot module for sure on rack, also cfg in HW for sure. My guess...

Update: don't forget after remedy (cfg change, parametrization,...) to turn off/on system to take effect.

Hello,

hope you've solved that diagnostic with module at slot 15, or? Wrong cfg or replace of module is expected if you have another free one. Don't hesitate post news.
