This object contains attributes common to many Metasys system objects. These common attributes are described in the Common Object Attributes section. This section includes attributes unique to the Global Data Sharing object. See the Object and Feature Tabs section for information on the attributes that appear on the other tabs of this object (for example, the Hardware and Options tab appear on point objects).

Table 1. Global Data Sharing Object Attributes
Name / View Group

Attribute ID Writable (W) Configurable (C)

Attribute Description
Enabled -- Object

673 C W

Indicates whether the Global Data Sharing object is enabled or disabled
Set Up -- Engineering Values

518 C

Defines whether the Fail Soft or Last Reliable value needs to be the output if the object becomes unreliable.
Master -- Engineering Values

1059 C W

Contains an attribute reference. The value associated with this attribute is written to each of the designated slave destinations.

Alternate Master -- Engineering Values

895 C W

Defines an alternate to the Master. When the Master becomes unreliable, this attribute becomes the master attribute.
Slaves List -- Engineering Values

1061 C W

Contains a list of attribute references. Each slave identified in this list of attribute references receives its value from the Master.

Refresh Timer -- Engineering Values

2325 C W

Indicates the amount of time, in minutes, between updates to the slaves from the Master or Alternate Master. Updates initiated by the refresh timer occur in addition to updates initiated by a COV from the Master/Alt Master. For example, if the Refresh Timer attribute’s value is 2, the Global Data Sharing object updates the slaves with information from the Master/Alt Master every 2 minutes and with each COV.

If this attribute is set to zero instead, updates are only sent upon receipt of additional COV reports.

Failsoft -- Engineering Values

2567 C W

Routes to all the outputs if Setup is configured as Fail Soft. Fail Soft routes when the object becomes unreliable and when the output transitions from Reliable to Unreliable. This attribute is initialized to a specific value.

Priority For Writing -- Engineering Values

88 C W

Defines the priority at which the referenced attributes are commanded. Seven is the highest priority and 16 is the lowest supported by the Global Data Sharing object, with the default of 15.

Note: We do not recommend using priorities 7 or 8 as they may interfere with the operator override function.
Execution Priority -- Execution

2197 C W

Indicates the relative importance of performing the function of the object within the device.
