Introduction

TSENTRY is a general-purpose, stand-alone process control computing platform. It comes complete with all facilities required to support deterministic real-time program repetition rates as fast as 1 millisecond. It provides a basic computing platform for hosting custom monitoring, control, and signal processing applications.

This platform utilizes industry standard hardware architecture, system software, program development facilities, human-machine interface facilities, and communications protocols. This reduces the cost and complexity of expanding and upgrading the system as necessary to keep abreast of rapidly changing computing technology.

The following sections provide an overview of the TSENTRY system and general information about its operation.

The TSENTRY documentation is available in two formats:

Interactively on the web at http://www.tsentry.com/TsentryHelp
