Can ZBRN1 with ZBRCETH work on a multimaster Modbus connection?

[Veronika1]

Dear Experts,

I have a question, ZBRCETH module has 2 Modbus TCP/IP ports with daisy chain topology but I need to confirm if I can comunicate the ZBRN1 with a HMI and a PC simultaneously.

Thanks for your assistance.

Regards.

ZBRN1+ ZBRCETH being a slave modbus tcp device it can answer to multiple masters. Not sure what you refer to with HMI, but ZBRN1 is not supported by SMD MV no SMD LV.

Hi Expert, does ZBRn32 supported by SMD MV and SMD LV?

Hello @Gig_DSA , 

Answer is yes for SMD MV. But Panel Server can also replace the ZBRN32 for SMD MV.
No for SMD LV (you must use Panel Server or PowerTag Link regarding your application).

Please refer to the ESXP IEC Design Guide (section Thermal Monitoring) for more info.

For SMD MV only ZBRN32 is supported

For SMD LV PTL or PAS(depending on location) can be used
