SIDIR comms issue

Good day,

I trust you are well.

We are currently experiencing an issue with the Siemens SIDirect drive,

The problem arises when the MixerB_S7300 PLC is offline and the AOS server is restarted. In such cases, all mixers under the associated port lose communication.

[Admin] Operations Integration Supervisory Servers
├─ Internal - SIM
├─ Modicon - MBTCP
└─ Siemens - SIDIRECT
└─ OI.SIDIR.1
├─ Configuration
│ └─ PORT
│ ├─ MixerA_S7300
│ ├─ MixerB_S7300
│ ├─ MixerC_S7300
│ ├─ MixerD_S7300
│ ├─ MixerE_S7300
│ ├─ MixerF_S7300
│ ├─ MixerS_S7300
│ └─ Waterplant_S7300
└─ Diagnostics

To restore communication, I’ve found that it is necessary to disable MixerB_S7300 and restart the communication services while keeping the offline PLC disabled.
please advise if this is the correct way

Thanks.
