Abstract

NOTICE: This Document was completely rewritten in 2019.

The purpose of this Standard is to provide a communication interface specification, to be used for the equipment control in flow shop type manufacturing line, that has the following capabilities.

· Simultaneous transfer of Material and its Material Data between adjacent equipment

· Transfer of general-purpose data between equipment

· Transfer of general-purpose data between the host and equipment

The purpose of this Standard is to provide a communication interface specification that can also be supported by cost effective controllers such as Programmable Logic Controller (PLC).


The scope of this Standard is to define communication interface specifications for equipment control in a flow shop type manufacturing line, which includes:

· A handoff interface that transfers a Material and its Material Data simultaneously between adjacent equipment

· A communication interface that transfers general-purpose data between equipment or between the host and equipment
