Not that i'm aware of.

Also,modbus as a protocol itself does not suppport authentication.

Back to DCE,it only reads device sensor data via modbus tcp,no write /control.

Dear Lal,

I agree with Chris. As far as I know, the modbus protocol itself does not support authentication feature as the way SNMP has. 

Therefore, authentication is not available in DCE for modbus device communication.
