S5 connection with S7 via CP541


Thread Starter


I have configured the CP541-card( DB1), and then I configured DB1 in the S5-95U. Next step: configuring S7: inserting the gsd-file, making a new profibus slave, and then tell how manu IW and how many QW there are.

If I then start the CP541: no error on this card, and no error on the S5-95U, but my S7 gives me a fault-message: "module not available"
Expected: DP-slave (ordern° ???)
Existing: s7-CPU (ordern° ???)

The rest of my profibus-network is still working...

Can anyone help me out?
