Rodrigo N. Posts: 39 Rating: (0)	Hi J_Bell, Is there any way to connect a Profibus CP342-5 in the ET200M? This way I would not have to get worried about switching the connection of the gateway between both CPUs in case of fails. Thank you very much, Rodrigo

Hello Rodrigo;
You can use CPs in withh the different IM 153-x modules that act as head of a ET 200M station.
See this table from a Siemens udate on the new IM 153-2 High-Feature module

Interface Module	Function
IM 153-1	Profibus DP standard slave with DPV1 and S7 functionality, Basic functions for operation with simple FMs, CPs of the S7-300 module spectrum (see User Manual for more information) For standard applications
IM 153-2	same as IM 153-1 plus full functionality for connection of FMs, Ps,... Redundant applications for S5, S7, S7 software and S7-400H Time tags and clock synchronisation Transmission of parameterization data to intelligent field devices
IM 153-2 High-Feature	Same functions as IM 153-2 In addition the above new functions Redundancy to Profibus V2

Hope this helps,
Daniel Chartier

Rodrigo N. Posts: 39 Rating: (0)	Hello! So can I use the following architecture annexed? Can I use Profibus CP with the IM153-2? The CP in the ET200M must be master, to connect with the gateway. Thanks, Rodrigo Attachment Architecture.pdf (316 Downloads)

Rodrigo N. Posts: 39 Rating: (0)	Dear J_Bell, OMG man I am really lost.... So instead of using CP342-5, can I use CP341 (modbus)? Changing the gateway too for sure. Thanks, Rodrigo

J_Bell Posts: 5822 Rating: (412)	Dear Rodrigo, I think this should work, but here I would use the CPU DP interface as DP Master instead of the CP, the CP may be used for the HMI connection. But, in this special case I have to say that I am not sure how the functions needed for the MODBUS communication work in the redundancy case... this would be something to be verified. Best regards J_Bell
