*1. The Object_ID and Object_Name Properties of Device are writeable.

*2. The Present_Value Property of some AV and BV objects is commandable.

*3. Only Commandable objects support Priority_Array and Relinquish_Default.

The AV objects, we have commandable and readonly cases.

Commendable case: We can use Write_Service to access the Present_Value property of commandable

AV objects. Thus, the commandable AV objects are linking to the Control_Word and Pr_Word in CP2000.

Readonly case: We can use Read_Service to access the Present_Value property of readonly AV objects.

Thus, these readonly AV objects are linking to the Status_Word in CP2000.

The BV objects, we also have commandable and readonly cases.

Commandable case: We can use Write_Service to access the Present_Value property of commendable

BV objects. Thus, the commandable BV objects are linking to the Control_Bit in CP2000.

Readonly case: We can use Read_Service to access the Present_Value property of readonly BV objects.

Thus, these readonly BV objects are linking to the Status_Bit in CP2000.
