One tcp modbus master can have 32 slaves. Does it work well, if I add other tcp modbus master and 32 other slaves ?

To get 80 slaves, did you add 3 Modbus TCP Masters?
Can I ask how much data you read from each slave?

thanks

One Master can have 32 Slaves. After that, you will not be able to add another slave. You can add maximum of 10 Modbus Master. So you can have maximum of 320 slaves for one Application. I tried it with nearly 300 and it worked.
