SEMI PV2-0709 - Guide for PV Equipment Communication Interfaces (PVECI)

SEMI Standards Copyright Policy/License Agreements

Status

Abstract
This standard was technically approved by the global Photovoltaic Committee. This edition was approved for publication by the global Audits & Reviews Subcommittee on May 13, 2009. It was available at www.semi.org in June2009 and on CD-ROM in July 2009.

Purpose
The purpose of this guide is to define the IT equipment automation/integration interface of process, automation and metrology equipment used in photovoltaic (PV) manufacturing. It intends to produce economic benefits for both manufacturers and equipment suppliers. On the one hand the standard is expected to release PV manufacturers from the burden to specify the interface with each equipment supplier and to facilitate an increased level of functionality across all manufacturing equipment. On the other hand it will reduce the effort equipment suppliers currently have to spend to develop and maintain a variety of equipment interfaces. Altogether, it is expected to reduce both costs and time required for the ramp-up of new production lines and thus supports the industry’s ability to grow.

The document references a collection of SEMI and other standards and gives hints how to apply them in PV manufacturing environment in order to establish a reliable and extensible framework for the IT integration of equipment.

The guide for PV equipment communication interfaces applies to equipment used in PV manufacturing lines; independent of the base technology used (such as crystalline or thin film). It is mainly intended to be applied to cell manufacturing, module manufacturing or frontend/backend manufacturing — however it is not limited to these areas of application.

Scope
The scope of this guide is limited to the IT interface used to integrate equipment within factory automation systems.

This guide can be applied to inline equipment as well as batch equipment. Basically a piece of equipment can be seen as a mechanical entity in the factory which plays a role in the manufacturing process. It can be used to transport, store or process material and can have a modular structure. Figure 1 is an example structure of a piece of equipment. A host is a computer or a network of computers which exchange information with the equipment in order to fulfill manufacturing tasks.
