RAR2405 Remote Access Platform SIGMATEK

SIGMATEK Remote Access Platform Model RAR2405

The SIGMATEK RAR2405 is a Remote Access Platform (RAP) device designed for connecting automated control systems in industrial plants, allowing users to access PLCs and compatible devices from outside the facility via a VPN connection.

The unit features a SIM Card slot for internet connectivity and supports communication protocols used in industrial systems such as Modbus TCP, OPC UA, Siemens, Ethernet/IP, and Logger API.

RAR2405 allows remote screen control access through VNC Client on both computers and mobile phones. It also supports HTTP Client connections to compatible systems.

In addition, it can utilize Cloud services for data storage, live monitoring status display via Dashboard, exporting data as Excel files, and setting up email notifications. The Cloud service comes with fees based on specified conditions.

VPN Connection for Remote PLC Access

RAR2405 supports connection through a VPN to allow users to access the PLC from outside the installation area. This is suitable for system control checks, problem analysis, and remote maintenance support.

The use requires proper network configuration, access rights, and security systems. The ability to access each model of PLC depends on the supported connections and protocols.

SIM Card Internet Connection

The device has a SIM card slot for internet connection, suitable for machinery installation locations that require connectivity channels for remote access services.

Before choosing to use it, check the type of SIM card, mobile network support, service area, and internet package. The catalog does not specify fixed values for mobile network types or connection speeds.

Industrial Communication

Communication	Description
Modbus TCP	For data communication with devices supporting Modbus TCP
OPC UA	For data exchange with systems supporting OPC UA
Siemens	Supports communication formats with Siemens equipment as per system requirements
Ethernet/IP	Supports communication according to the catalog listings, requiring verification of connection format and role
Logger API	For data connectivity based on Logger API capabilities
HTTP Client	Supports HTTP Client connections as per usage requirements

The support for protocol names does not mean that the device can automatically connect to all PLC or machine models. Detailed operation should be checked, such as data reading and writing formats, Client/Server roles, and endpoint device protocol support before actual use.

HMI Screen Access with VNC Client

RAR2405 can work with a VNC client to remotely access supported screens via computer or mobile phone according to system settings.

This function can be applied for machine status screen monitoring and remote operation through the screen when the system is designed to support it.

External machine control authorization must have permission controls and security conditions to prevent dangerous operations that may harm personnel or production processes.

Cloud Data Logging System

RAR2405 supports cloud data logging for tracking and monitoring operational status using the capabilities of cloud services.

Data logging system design should specify variable lists, data collection frequency, storage duration, and service usage conditions to suit project requirements.

Note: Cloud use incurs fees, and details such as storage space, number of variables, and retention period must be checked from the selected service package.

Cloud Dashboard and Live Monitoring

The device supports live monitoring data display through the Cloud Dashboard to help users track system performance metrics remotely.

The displayed information depends on the source device, configured variables, and cloud platform capabilities. The dashboard layout and access permissions should be verified according to system requirements.

Data Export as Excel File

RAR2405 supports exporting data from the Cloud to an Excel file based on catalog data. This is suitable for using recorded data to analyze trends, operational performance, or generate reports as needed.

The data format and time range that can be exported depend on the cloud system and service conditions.

Email Notification System (Cloud Notification)

Cloud Notification settings can be configured to send email alerts. This is suitable for monitoring predefined events such as operational status or variable values reaching alert thresholds.

The number of notifications, conditions, and message formats must be verified from the actual cloud service being used.

Application Examples (Applications)

• Remote connection and access to PLC
• Machinery system monitoring through VPN
• Remote HMI system via VNC Client
• Machine status tracking through Cloud Dashboard
• Data logging from machinery through the cloud
• Status or event notification system via email
• Multi-site factory machine inspection system
