Hallow Experts,

We are upgrading the Master slave system from Profibus to RCOAX communication using CP343-1 7 SCLANCE 700.

But after configuring CP 343-1 (after creating CP network. See fig, no. 3.1 ) in hardware configration of master PLC, Node configured on Profibus network are are not accessible to Laptop as shows error in fig no. 4. Trial taken by adding router setting also. Also not able to communicate with RCOAX node. Checked by connecting Profinet cable to both separate network. (CPU and CP.)  Both CPU and CP network are separate.

Node configured on CP Ethernet network found OK means communicating with CPU 317 and no any SF/BF found on CP. 

CPU Ethernet network is also required for other communication purpose. So please tell me there is any limitation for using CPU and CP network at same time.

Or Please tell me how to configure the same.

Thanks

Hello,

only one idea, check all available MPI and DP addresses on modules, maybe there can be problem with same values. All must be unique. Another question, maybe I'm wrong but I'm curious, did you consider use PN port on CPU instead of CP card? Only for test if it can be configured for your needs.

Update: simply due your error with online I see probably problem with MPI addresses. Also CP card reserves MPI address so check that and also correct download HW cfg.

Thank you for replay,

All the DP address are OK and there is no any change in value. When we configure CP as attached figure-1 (Not Configured) then only all DP slave are communicate with laptop. (Set PG PC is TCP/IP).

Still I am not understand when we set set PG PC of laptop to TCP/IP, and configure the CP with new network as figure 2. Then none of DP slave configured on CPU-DP network are not communicate with laptop when Set PG/PC is TCP/IP.

As per one of the expert in Siemens,  in this configuration we can't communicate with normal PC. For this need Siemens PG.

Still we will try something with the help of you............. 

hi Amol Jangam,

what is projected in Netpro?

Can you show us a screenshot  of the configuration there?

regards,

Hi

Configuration in Netpro is attached here
