[?]: More than 31 slaves with 314C-2DP

Post by Scarch »

Hi,
I have CPU 314C-2DP full with 31 slaves in Profibus.
Now I need to add 6 more stations (drives).
What is the cheapest way (CP reference)?
Can Not use MPI or Ethernet.
I also have 1 MP377 which is used actually in MPI.
Something to do with the winAC on there?
I can set the winAC as Profibus master but the how I access the main profibus network?

Hello,

From manual http://support.automation.siemens.com/W ... n/12996906:
manual wrote:1. First interface could be use only with MPI functionality (max 12 connections).
2. Second interface could be use only with PROFIBUS DP functionality (max 32 slaves).
Return back to main question - chiepest solutions ia CP342-5.
Use like DP master.
All drives will be slaves.

best regards,
Umencho
