The ioLogik E2210 handles the alarm system of walk-in refrigerators in a semiconductor factory.

Project Background

A semiconductor factor preserves its stock of epoxy resin and

silicon-based materials in large walk-in refrigerators at

temperatures below 5°C. Temperatures higher than that will

cause both the physical and chemical characteristics of the

materials to change. This renders the materials unusable and

lowers the factory’s production. The temperature increases in

the refrigerator are primarily due to the fact that the doors are

not usually closed all the way when employees come in and

out. As a result, an alarm system was requested by the

semiconductor factory to monitor the refrigerator door.

Application Requirements

The system requested basically needs to monitor the opening and closing of the walk-in

refrigerator door. It takes a factory worker an average of 1 minute to enter the refrigerator, locate

the appropriate materials, and exit the refrigerator with the materials in hand. An alarm must be

generated when the door remains open for over 1 minute. Due to the tight timeframe available for

deploying the alarm system, engineers needed to find a quick solution that did not require

extensive programming or complicated communication protocols. In addition to local control

capabilities for the door sensor and alarm, the semiconductor factory also required a solution that

would allow complete connectivity with a central PC or ERP/MES system.

Moxa Solution

The ioLogik E2210 Active Ethernet I/O server is designed for combination I/O applications. The

12 digital inputs can connect to different door sensors and switches and the 8 built-in digital

outputs provide flexible connections to multiple alarm devices. Unlike programming a front-end

PC or stand-alone PLC, the ioLogik’s Click&Go control logic uses an easy to use IF-THEN-ELSE

style of programming that doesn’t require any compilers or debugging tools. The ioAdmin utility

also allows users to configure the alarm system within 5 minutes with the click of a button.

Moreover, the ioLogik E2210 provides both Ethernet connectivity and several ways to update

status including e-mail warnings, TCP/UDP active messaging, SCADA/OPC connectivity, and

SNMP trap I/O reports.

Solution Benefits

The ioLogik E2210 provided the semiconductor factory with the following benefits:

9 A controller equipped with both digital inputs and digital output channels

9 Click&Go’s easy IF-THEN-ELSE style control logic, which eliminates the need for a PLC

or RTU

9 Simultaneous control for local and remote Ethernet

9 Alarm messaging via TCP/UDP/SNMP trap or e-mail

9 Compact size and cost-effectiveness
