[?]: Profinet BF with a CPU 416-3PN/DP

[FLETCHER]

The PLC is a CPU 416-3PN/DP

Hello.
I'm a newbie using profinet and I have one problem with no siemens slaves.
When I have a cold restart, non siemens modules stay in Bus Fail.
I need to shutdown the power supply of that modules and after, the modules go to run.

How I can restart the modules from the program. Whithout cut the power supply.
At this moment I do not use SFC or SFB for the manage of that modules.

Modules are a festo valve station with an CMMS-AS (Axis Controller)
And a Lumberg I/O device.

Thanks.
