1 What
is
EZT-430i?
The EZT-430i system combines all of the features of a loop controller, video/chart recorder and data logging
system into a single/intuitive device. Email, SMS (text messaging), FTP (file transfer protocol for automated
data backup) and remote view/control (Web server/VNC server) are standard with EZT-430i and can be
accessed via LAN/WAN using a PC, tablet or smart phone device.
Future Designs “EZT-430i” provides a 4.3”color touch screen interface with standard “Smart Device” user
interface features for single and dual loop OEM control applications. All loop configuration and runtime user
access is configurable at the device with no PC software required. OEM’s have the ability to configure
runtime features (screen availability, menus, language, etc...) to easily customize the system for their
requirements. These configurations can be imported/exported to any other EZT-430i single/dual loop device
for setup (from scratch) within minutes.
Individual high performance board level PID loop control boards (one for each loop) offer up to four control
outputs each, powerful profiling capabilities with up to three events and full auto tune functionality with high
resolution process inputs.
1.1 Features
Each of the EZT-430i loop control boards provide a single digital input that can be programmed as a
automatic program control input for run, hold or abort, a manual mode or failure transfer control input or a
program advance to next segment control input.
Each of the loop control boards also provide up to four control outputs which can be used as PID control
outputs for heat/cool, direct outputs for controlling external equipment related to the application through
software switches called events, or be programmed to act as system alarm outputs.
EZT-430i can be operated in single set point or automatic program control mode. Program entry is made
easy through the use of copy, paste and delete menu selections. Programs can be copied to the external
USB memory stick and then imported to another EZT-430i controller which eliminates the need to enter
duplicate programs into multiple systems.
Data file analysis tools make looking at historical data a simple task. Any control variable saved to the data
file can be plotted on the historical data chart for any time frame within the data file’s total time range.
The built in Ethernet functionality includes a ‘Web Server’ to provides access to all EZT-430i data (view only),
a VNC interface for remote control and monitoring and an NTS clock, all available via a local Intranet
connection (wired or wireless), or the World Wide Web using standard software like Microsoft’s Internet
Explorer.
EZT-430i provides a rich set of tools for control interaction and process monitoring. Views include single and
dual loop views, charts, alarm, automated program status as well as historical data, alarm log and audit trail
views. The menu driven interface eliminates screen “clutter” by providing an easy to use “Smart Device”
interface for interaction between the user and EZT-430i.
EZT-430i can store more than one year of data on its SD memory card. Data logging can be enabled
manually or automatically during program operation. Data backup is provided with a USB memory stick for
plug and play transfer of files to any PC running Microsoft Windows XP operating systems and via the FTP
back-up utility.
EZT-430i protects system access with 4 level security (user rights based), audit trails that document all user
activity and ensures data integrity by digitally signing all data files and audit trails to meet regulatory
requirements.
