Seize Regulator module<br />
DESCRIPTION<br />
A tank regulator may be used for only one flow operation at any given time.<br />
The Seize Regulator module allocates one or more regulators to an entity. When an<br />
entity enters this module, it waits in a queue until all specified regulators are available<br />
simultaneously. An allocated regulator is released by an entity using the Release<br />
Regulator module.<br />
TYPICAL USES<br />
• Controls ownership of regulators and avoids multiple entities trying to use the<br />
same regulator in a Flow module simultaneously<br />
• Chooses from a set of alternative regulators using a selection rule<br />
