Iec60870 104 slave driver process gateway

Hello Team,
I am using IEC60870 104 fieldbus in zenon logic as slave as a process gateway.
I have added certain no. of IEC61850 double point information to the gateway. Now in the client side of the gateway I am getting readings like shown below:
For off status in slave = 2 in client.
For on status in slave = 0 in client.
For faulty status in slave = 1 in client.

According to iec standards
0 should be intermediate
1 should be off
2 should be on
3 should be faulty

Please suggest on the above
