Dear Experts

Here i have used s7-400 CPU416-3DPas master.the s7-300 cpu 315-2dp as slave.
s7-300 system not with inmy projectconfiguration.that one is supplied by other vendor.

s7-300 system configured as an slave by other vendor.

I installed gsd files for cpu315-2dp.
then i open s7-400 hw configuration,i have configured that s7-300 cpu as slavein dp master network From profibus DP---Additional field device--PLC---Simatic--cpu315-2dp

when i down load the hw configuration at s7-400 sidethat time not detect that s7-300 slave.

s7-300 side showing bus fault-1 with blink and also SF fault..

I did following setting
1) 1.5mbps both slave and master
2).s7-300 hw config i have set slave
3).exchange data mapping

Kinldy give us solution

Iam in bottle neck.

Thanks in advance...

see:Master-slave connection between two CPUs in different projects

s7-300 side showing bus fault-1 with blink and also SF fault..

LEDs of CPU 315-2DP in SLAVE mode:
SF DP is on and BUSF flashing, in this case ,parameters of the
CPU 315-2DP is not correct.There is no communication between CPU 315-2DP
and the master.Check the configuration and parameters of CPU 315-2DP
and make sure bus cable is intact and there is no problem in BUS connector.

Check the attachment for correct bus connection of combination of 3
stations in a PROFIBUS set up.(and terminating resistors)

Dear Experts

Thanks for all the reply.I was made wrong parameter assignment in slave side.After rectify the same communication got healthy.
