kindly confirm is it possible to connect 8 NOs of LTMR100MFM relay in daisy chain connection and it is programmable in GXU HMI.

It is recommended not to connect more than 8 nos of LTMR relays with a single HMI GXU3500 using Modbus RS485 communication in daisy chain.

Also you can use HMI XBTN410 with LTMR and it is not having any program backup but I have attached a sample backup of XBTN with LTMR for your reference. For loading this program backup you need to use XBTL1000 software available from Schneider Electric`s website.
