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 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).

Initial Value

Values/Options/Range

Description

Alternate Manager

C,N,W

None

  Defines an alternate to the Master. When the Master becomes unreliable, this attribute becomes the manager attribute.

Execution Priority

C,W

Normal

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

Failsoft

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.

Manager

C,W

None

 

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

Present Value

C

Manager

n = 4

0 = Manager, 1 = Alt Manager, 2 = Last Reliable, 3 = Fail Soft

Stores data about the value shared with the subordinates.

Priority For Writing

C,W

15

16 (lowest priority) to 7 (highest priority)

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 object, with the default of 15.

We do not recommend using priorities 7 or 8 as they may interfere with the operator override function.

Refresh Timer

C,W

2 min

Default value is 0. No range check done.

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

Reliability

   

Reliable, Input Unreliable

Indicates whether a value is questionable. This attribute value equals Input Unreliable only if both the configured Manager and Alternate Manager inputs are unreliable.

Setup

C

Last Reliable

n = 2

0 = Manager, 1 = Alt Manager

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

Subordinates List

C,N,W

None

Minimum number of entries = 0

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

1 C - Configurable, N - Value Not Required, W - Writable
