The SEMI E30 GEM standard describes how communications and control capabilities should be supported between a factory host (MES) and production. GEM SEMI standard (Generic Model for Communications and Control of Manufacturing Equipment) describes how a semi-conductor equipment shall. Introduction to the SEMI Standards: SECS/GEM.

Often both protocols are supported.
It is typical that a connection is maintained for long periods of time and only interrupted if the equipment or host is rebooted. The distinction is that a Data Value Variable does not always have a valid value.

SECS/GEM – Wikipedia
Delete equipment existing report definition”. Logger “Communication disconnected”. Logger “Define all report accepted”. NET software includes the SecsHost component which can be used from any. Acknowledgement from our EnableAlarm false – Disable all alarm.
The Java SecsHost class library is similar, but it is expressly for Java. Also, the reply messages may be sent in a different order than received. The event report mechanism is general and powerful. SECS describes the communication between a host computer and the equipment using a single connection.
Niche Applications An equipment provider can deploy multiple SECS interfaces if he allows for coordinating machine control, for example by indicating to the extra host connections that the machine is under local control. Trace windows with dynamically adjustable views are available for each connection. An equipment provider can deploy multiple SECS interfaces if he allows for coordinating machine control, for example by indicating to the extra host connections that the machine is under local control.
One of the benefits of a standard interface is that dissimilar equipment is integrated into the factory in the same general way, with the same conceptual model. The Hume message system provides a dynamic connection interface, allowing you to bring equipment and processes off-line or on-line in perfect synchronization.
There is sufficient complexity with SECS and automation applications in general that support issues in the field are not uncommon. The applications manage multiple equipment interfaces, and they feature built-in handling of most of the routine SECS message conversations. An example might be to begin executing a specified process program. For this challenge, a premium is placed on flexibility, and working with a high-level, productive environment with excellent runtime visibility into the proper functioning of his low-volume applications.
Logger “Define all report not accepted. The equipment provides three basic levels of host control, which determine the host’s ability to control and monitor the equipment. Variables SECS identifies three categories of variable data items.
SECS/GEM Standards Overview
GEM intends “to produce economic benefits for both device manufacturers and equipment suppliers The following code shows you how to perform initialization and establish communication with equipment using SecsToTool. The hostController subscribe to events: Trace Reporting Tem reporting is a feature that provides for periodic reporting of selected variable values.

Logger “Unlink event report is accepted”. In the constructor we create an instance of SECsHost object that provides the library of methods for your host application to send messages to equipment.
Data from event reports can be collected by the driver, combined with context information, and sent to a persistent database for later analysis and reporting.
Even the same tool may have different interface behavior over its short lifetime as its control software is upgraded. In particular, message types that provide for sending command invocations to the equipment with optional arguments are defined in the standards as Remote Commands. Logger “Establish Communication not accepted.
The host determines which collection events and alarms are set up for notification. Developed by the SEMI Semiconductor Equipment and Materials International organization,  the standards define a common set ge equipment behaviour and communications capabilities. Process Programs Simpler equipment that supports remote control of processing may use a set of Equipment Constant Values to define processing setpoints.
Sometimes the issue is only one of understanding but there can be problems with non-standard or buggy implementations particularly with older equipment or when a mature toolset has not been used.
