OB for DP Slaves Reset after downloading program

Hello all! 

I need for my S7 315-2 PN/DP CPU and organization block (or something like that) that will reset my peripheral profibus slaves after a new total load of the plc program into the CPU. 

I have some frequency converters and other DP slaves, that after the loading of the program need a manual reset. 

Is there an organization block, or another method to "automatically" reset these drives after the loading of the project into the plc? 

Thank you in advance!

hi cioara,

like plewandowski said, you could do something like that in OB100.

OB100 is an organisation block that is runing only once at the start-up of the CPU. You have to programm the reset-procedure in it.

Most of the delivered controll-blocks have a resart input where a restart-marker should give information of a start up of the system.

hope this helps,  

regards,
