Hi,

We are quoting for a system involving Zone 1. Please refer to architecture attached. Please confirm the architecture is ok. Also, I have the following queries:

1. Do I have to use CP1628 on PC "C"? Or simple CP1623 will do?

2. For taking the ethernet cable to the Panel PC Ex "B", a Third Party Barrier is ok or any Siemens product is there? 

3. For Profibus cable in Zone 1, special profibus cable is there. Is there special Ethernet cable for hazaradous area? If yes, type no.?Also, what type of RJ45 connector shall we use for hazardous area?

Anything else we should keep in mind?

Regards
