Me is necessary to read from ET200 with 2 CPU315
Probably it whether or not?
thanks

Hi
Let's make some conditions:
1. Both CPUs are masters in Profibus network.
2. This ET200 is a slave, which is connected to the one master CPU.
3. Now, If you want to read information from this sleve with 2 CPU, must make connection between them.
4. Use DP/DP coupler to connect 2 profibus network (2 master).
5. DP/DP Manual link: https://support.automation.siemens.com/ ... nload=true
6. Another decision is to use 2 CP, connected to the 2 CPU, and make ISO Ind. Ethernet connection between 2 CPU.
7. The cheaper decision is to use DP/DP coupler - 444 EURO (at Germany's border)
And maybe someone have another decision
regards

Why I should use DP/DP coupler?Umencho wrote: 4. Use DP/DP coupler to connect 2 profibus network (2 master).
5. DP/DP Manual link:
I want to use only one network
Also would not be desirable to transmit data through one of CPU.
Because any of CPU can be switched off at ahy time.

Hi
Sorry, I don't understand your project with previous post. You want to build something like redundancy system. One of the CPU is main, other stay in stand by, isnt't it? if something happend with main CPU the other take leader function. I think this depend from possibilities of the CPU. At the moment I cant help you. Tomorrow i'll check this situation.
