Cannot display big value

Cannot display big value

I'm doing an integration with Alstom DCS using process gateway and forward it back to an erp system. It connected to DCS using IEC 104
The problem is if the value within the INT range, it works. otherwise doesnt work eventhough i've set to datatype DINT @ REAL.
i've set in value calculation to -99999999 to 99999999 for both value range PLC and value adjustment linear.
