shared tags.

Produced tag A tag that a controller makes available for use by other controllers. Multiple controllers can simultaneously

consume (receive) the data. A produced tag sends its data to one or more consumed tags (consumers)

without using logic.

Produced/consumed tags

Chapter 1 Produce and consume a tag

10 Rockwell Automation Publication 1756-PM011K-EN-P - September 2020

Term

Definition

Consumed tag A tag that receives the data of a produced tag. The data type of the consumed tag must match the data type

(including any array dimensions) of the produced tag. The RPI of the consumed tag determines the period at

which the data updates.

Keep the following considerations in mind for produced and consumed tags.

•The tags must be controller-scoped tags.

•The data types must match, including user-defined data type layout.

•The size of the produced and consumed standard tag is limited to less

than or equal to 500 bytes.

•A produced/consumed tag can only be created when the controller is

offline.

•Connection status information can be included with the produced tag

in a standard controller. In order to do this, create a user defined type

whose first member is a CONNECTION_STATUS type. Then, the

remaining members in the user-defined data type contain the data to

be produced.

For produced and consumed safety tags, these requirements are mandatory:

•The size of the produced and consumed safety tags are limited to 128

bytes.

•Connection status information must be included with produced and

consumed safety tags. Create a user-defined data type whose first

member is a CONNECTION_STATUS type. The remaining members in

the user-defined data type contain the data to be produced.

•The Class field must be set to Safety.

•Safety tags can only be modified when the safety application is not in a

safety secured state.

•Compact GuardLogix 5380 and GuardLogix 5580 Safety controllers can

only produce safety tags as unicast. These controllers can consume

safety tags as either unicast or multicast.
