Urgent communication between Schneider m340 and honeywell dcs

hello everyone
we work on a water station using plc schneider M340 and we should make a communication with a dcs honeywell , this dcs should read a variables from my plc i have a ethernet module BMX NOE 0.100
i put the ip adress but the dcs show that the variables are not online

I'm assuming the DCS is trying to read data using Modbus TCP.

How have you defined the data you're trying to read in the DCS?

Do you have corresponding located variables (i.e. tags with addresses) within unity?

Have you tried using a modbus client on your PC to see if the PLC data is accessible?

Please provide more info
