EKI-1331 User Manual 2
1.1 Introduction
The EKI-1331 combines 3G networks, intelligent protocol conversion, and VPN
technology to create a product designed for remote maintenance and management.
The EKI-1331 features remote communication between the controller and data
center, which provides an ingress (or gateway) for the remote diagnosis and
maintenance of the machines. The controller technicians can construct large-scale
networks for remote maintenance of equipment. The EKI-1331 can also be employed
as a communication gateway for equipment to coordinate with each other.
With the EKI-1331, technicians in the office can remotely program field PLCs,
monitor variables and receive alerts in real time. The EKI-1331 supports both
communication via the PLCs Ethernet port and via the serial port. EKI-1331 also
supports status queries, PLC controls and alarm message via SMS. The EKI-1331
series utilizes the ubiquitous cellular network to the fullest and opens new horizons in
remote management and machine to machine communication.
1.2 Features
 Designed for the Communication of Industrial Equipment
– SMS Function
SMS Alarm: users can receive timely alarm message when PLC exception
occur in field.
SMS Check and Control: users can remotely monitor and control PLC.
PLC Collaboration: PLCs can communicate with each other via SMS, ensur-
ing more PLCs work collaboratively.
 Remote Maintenance
Users can achieve PLC’s remote programming via secure channel (serial/Ether-
net pot)
 Remote Monitoring
EKI-1331 can check real-time operating status (variable) and send it to data
center regularly through 3G/2G network. Users can check PLC’s operation and
alarm messages anywhere via internet.
 Industrial Design
– In the aspects of EMC, anti-static grade, anti-surge level and wide tempera-
ture range, EKI-1331 meet the requirements of industrial and operate easily
under harsh environments.
– Metal enclosure. IP30.
– All EMC grade reach level 3.
– Ethernet port supports 1.5kv isolation transformer protection
– Serial port support 15kv ESD protection.
– Wide temperature range: -20?~70?.
– Wide voltage range: DC: 12-24V.
 Complete Security
– Data Transmission Security
EKI-1331 uses encrypted channel to communicate with remote controller,
enabling the process of updating PLC program enjoys high level of encryp-
tion, which is comparable to that of the financial industry.
– Network Protection Security
With powerful firewall features, EKI-1331 supports SPI State Inspection,
Secure Shell (SSH), Intrusion Protection, DDoS Defense, Attack Defense,
IP-MAC binding, etc, protecting the equipment against external network
attack.
