Analog Value Objects (PMC-53A-E’s Basic Setup Registers)
Optional Properties Supported: Description, Relinquish_Default, Priority_Array
Writable Properties: Present_Value, Out_Of_Service, Units, Relinquish_Default
Use the Present Value property of the Analog Value object for some writable variables in the meter
other than those used specifically for BACnet configuration or Time Synchronization. Values are
checked when written, and errors are returned for invalid entries. The table below describes how
the Setup Registers of the PMC-53A-E are represented in BACnet, their valid ranges, their defaults
as well as how they are used. PMC-53A-E supports the Description, Relinquish_Default and
Priority_Array optional properties. Writable properties include Present_Value, Out_Of_Service,
Units and Relinquish_Default, but Units are not non-volatile after modification.

Binary Input Objects (PMC-53A-E’s Digital Inputs)
Optional Properties Supported: Description, Reliability
Use the Present_Value properties of the Binary_Input objects as alerts for conditions of potential
concern regarding system measurements. These objects support the Description and Reliability
optional properties and all required Binary_Input object properties. None of them are writable.

Binary Output Objects (PMC-53A-E’s Digital Outputs)
Optional Properties Supported: Inactive_Text, Active_Text
Use the Present_Value property of the Binary_Output objects as alerts for DO conditions. Reading
Binary_Output objects have the highest priority. PMC-53A-E supports Inactive_Text, Active_Text
optional properties and all required Binary_Output object properties. Present_Value,
Out_Of_Service and Polarity properties can be written, but these are non-volatile after
modification. The Present_Value can only be written when the Out_Of_Service is true to change
the state of the Digital Output and will be written as W when the Out_Of_Service is false.
