The ioLogik E2260 provides temperature monitoring and alarm messaging for laboratories,

hospitals, and blood banks.

Project Background

Laboratories, hospitals, and blood banks refrigerate their

stocks of biochemical medicines, organic complexes,

solutions, and blood at temperatures between 2 to 8°C to

preserve quality. Constant monitoring is required to

prevent vaporization, chemical change, or contamination.

Therefore, alarm messages must notify staff immediately

if any drastic change in temperature occurs.

Application Requirements

The existing network uses Ethernet SNMP (Simple Network Management Protocol) to gather

necessary information such as network traffic and line status. Most of the I/O signal monitoring,

such as temperature monitoring, runs on Modbus/TCP or other proprietary protocols that take time

for IT engineers to learn. As a result, a temperature monitoring system for the freezers must be

established in a short amount of time and use SNMP protocol.

Moxa Solution

The ioLogik E2260 Active Ethernet I/O server is designed for mixed I/O applications. The 6 RTD

analog inputs are able to connect to 13 types of Pt (platinum) and Ni (nickel) sensors, in addition

to 4 types of resistance measurement. The 4 embedded digital outputs are suitable for triggering a

hard alarm locally. Most of all, the I/O status can be polled by the SNMP management software

from the control center. The ioLogik also sends out SNMP traps to report the current status when

the temperature becomes too high.

Solution Benefits

The ioLogik E2260 provided the freezer temperature monitoring system with the following

benefits:

9 I/O status control and monitoring via SNMP saves development effort.

9 Automatic SNMP trap reports.

9 A controller with both RTD inputs and digital output channels

9 16-bit high resolution measurement with more than 13 types of sensor connection

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

RTU

9 Compact size and cost-effectiveness
