Shifting from MODBUS TCP to DNP IP


Thread Starter

We are using SCADABR for scanning RTUs installed at various locations. Initially the RTUs were scanned on MODBUS TCP and everything was working fine. we are now shifting to DNP IP.

RTU DNP slave is configured for 32 Bit analog input only. (i.e. Obj 30, var 1) It is noticed that SCADABR DNP driver only polls for 16 bit data (i.e. var 2 only)

Please suggest how 32 bit analog input data can be scanned using SCADABR DNP IP Protocol.
