« on: February 02, 2014, 08:09:40 pm »
Hi,
anybody can help me to  explain how can i use SFB19 / SFB20 / SFB20
let me describe more :
PLCs S7-400 and S7-300 connected to ethernet network . S7-connection defined between them and at each side ID number is clear.
so i want to stop  S7-300 from S7-400 side by calling SFB20 in user program . Also i want to warm restart S7-300 from S7-400 side by calling SFB19 but none of these tests doesnot work !!!
please help
Thanks

Hi;
pay attention to followings:
1-most of s7-300 cpu doesnot support SFB19/SFB20/SFB21
2- first you should make s7_connection between 2 cpu in netpro
3-call SFB at one side and enter ID number 
so one cpu can stop/run another cpu via network
good lock
