Host Connectivity 

Host connectivity products are used in factory information and control systems to enable them to communicate with the wide range of manufacturing equipment that exists in an automated factory environment. 

Since the industry standards that govern communications between the equipment and factory control systems describe the entire end-to-end interaction process, the host-side connectivity products naturally mirror those found in the manufacturing equipment. In simple terms, we like to say that they implement “the other end of the wire.” 

Host Connectivity


Our latest product offering for creating host-side applications that easily connect to SECS/GEM equipment is HostConnect software. It features a layered architecture to support a wide variety of applications and interaction styles.

SEMI Standards Validation and Testing Tools

Early in the standards development process Cimetrix partnered with the International Sematech Manufacturing Initiative (ISMI) to provide reference artifacts to guide the industry and to ensure the accuracy, usability, and interoperability of SEMI standards implementations.

For the EDA/Interface A standards this resulted in the development of the Equipment Client Connection Emulator (ECCE). The latest version of this product is called ECCE Plus, and supports both Freeze I (1105) and Freeze II (0710) versions of the EDA standards. Consult the table below for more specifics.

Cimetrix has long supported the industry with products that equipment suppliers use to deliver SECS/GEM interfaces with their equipment. We likewise provide a test system they can use to validate these interfaces before shipping to their factory customers.
