CP 342-5

I have a problem with CP342-5

I used a CPU 317-2PN/DP with a PROFIBUS network and I need another PROFIBUS network so add a CP 342-5, when download HW config to CPU have an error.

Please help me to know how can use CP 342-5. Need any config or FC ?

Hello,

Yes, you need FC's to let CP342-5 function.

Please have a look at the following link:

What should you watch out for when configuring a CP342-5 as DP master and why is it necessary to call the FC1 "DP_SEND" and FC2 "DP_RECV" functions in the user program of the CPU in order to transfer data?
