ESTA E1.44 PDF

Reaffirmed in 2019

This standard is intended to address common show file requirements for automated stage machinery control systems used in entertainment venues. It establishes a minimum level of design and performance guidelines for the integrated software design of processor based machinery control equipment. The purpose of this guidance is to ensure that users will be able to transfer, modify and customize a ‘least common denominator’ show file for the data required to tour entertainment productions from one facility to another, even when the facilities’ physical conditions, hoist inventories, and placements, and the machinery control consoles and data topology differ.

Show file control functions addressed by this standard include:

• The relation between scenery and axes

• Grouping of axes

• Show cues and their basic content with:

Movements of axes or groups to pre-determined positions.

Movements of axes or groups in a linear or rotational fashion only. (with acceleration, constant velocity and deceleration).

At this time the standard does not include the following features, although amendments to include additional feature sets in later revisions of the standard are not precluded:

• Interrelated, dependent or interpolated movements.

• Movement effects.

• Multi-axis 3-dimensional flight-path movements.

• Rules or conditional Boolean logic.
