Database Addr
This field is the database address where the Metasys object's current value will
reside. Enter a value between 0 and 4095 (0x0 – 0xFFF).
A note for analog objects: Depending on the designated Data Type, the
maximum allowable database address is 4095, 4094, or 4092 for 8-bit, 16-bit, or
32-bit sized objects, respectively.
Multiplier
Applies to analog objects only. 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, the 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
the network data value. For example, if the data type is 8-bit and the multiplier is
0.5, then the network data can have values only up to 127 (since 255 is the
maximum value that can be stored in 8 bits).
Bitmask
Applies to binary objects only. This 8-bit field specifies which bit(s) in the byte
designated by the Database Addr that the binary object will map to. This allows
up to 8 binary objects to be simultaneously assigned to one database address
(each binary object mapping to a single bit of that byte in the database). It is
possible to map binary objects to multiple bits within the designated database
location. Such a configuration allows (for example) the modification of multiple
selected database bits via a single binary output.
The effect of the Bitmask field when writing: When the current state of a binary
output object is overridden to "1" by a Metasys master, then the bit(s) in the
designated Database Addr indicated by a "1" in the bitmask are set. Similarly,
when the current state of the object is overridden to "0", then the bit(s) in the
designated Database Addr indicated by a "1" in the bitmask are cleared.
The effect of the Bitmask field when reading: When the current state of a binary
object is read by a Metasys master, the Bitmask is used to determine the state
of the object by inspecting the value in the designated database address at the
bit location(s) indicated in the Bitmask. If all of the bit locations at the
designated database address indicated by a "1" in the Bitmask are set, then the
object's state will be returned as "1". Else, the object's state will be returned as
"0".
Data Type
Applies to analog objects only. This field specifies how many bytes are allocated
for the object's current value, as well as whether the value should be treated as
signed or unsigned when converting it to a real number to send over the network.
