Description
This field is a description of the service object. It is not used by the gateway, but
serves as a reference for the user.
Destination Address
This field is the network node address of the device that the gateway will send a
request to.
Type
This selects the object type to use in the service object. All objects in the service
object will be of this type.
Start Object
This field specifies the first instance number of the service object range.
Number of Objects
This field specifies the number of objects the service object contains in its range.
Database Address
This is the starting address in the gateway’s database that is used to mirror the
data on the network. The number of bytes allocated for the service object data is
determined by the data type and the number of objects in the service object.
Data Type
This field specifies how many bytes are used to store each object in the service
object. The data type also specifies whether the value should be treated as
signed or unsigned when converting it to a real number to send over the network.
Note that each data type has its own range limitations for what can be stored in
the database: 8 bits can store values up to 255, 16 bits can store values up to
65,535, and 32 bits can store values up to 4,294,967,295.
Multiplier
This field is the amount that associated network values are scaled by prior to
being stored into the database or after being retrieved from the database. Upon
retrieval from the database, the data is multiplied by the multiplier to produce a
network value. Similarly, network values are divided by the multiplier before being
stored into the database.
Note that the multiplier, coupled with the data type, imposes range limitations on
network data values. For example, if the data type is 8-bit and the multiplier is
0.5, then the network data can achieve a maximum value of only 127 (since 255
is the maximum value that can be stored in 8 bits in the database).
