Using 2 CU320 with the same ALM

Hello,

I have a configuration with 10 servo motors and I made a configuration using SIZER.

Here is the article numbers :

6SL3040-1MA01-0AA0 Control Unit CU320-2 PN

6SL3130-7TE23-6AA3  Active Line Module

6SL3120-2TE15-0AD0 Double Motor Module

I need to use 2 CU320 (with Profinet) with only one ALM.

I saw Here that this configuration is possible using DI/DO.

Would it be possible to receive the READY coming from the ALM using Profinet and send it back to the drives without using DI/DO. If it's possible, is there a manual about this ?

Best regards.

Hi,

yes this is possible via PROFINET.

On the ALM you can configure telegram 390. For your SIMATIC program there is a function block called "SINA_INFEED" with that block you can control the ALM (switch on) and you receive the feedback that it is in operation. 
This signal you can send back from the PLC to the drive (e.g. via supplementary data in your telegram).
