Samkoon 4G Module
Mobile-network connectivity for Cloud 3.0 on compatible Samkoon HMIs
The Samkoon 4G Module is a compact communication module that clips directly onto a compatible HMI. Automatic reconnection, offline transfer recovery, VNC and API functions support remote monitoring and service architectures; local carrier and frequency-band compatibility must be confirmed before deployment.

Four technical points that define the 4G Module
Module compatibility, cellular bands, data scope and remote-access permissions form one project.
Connection continuity
Automatic reconnection after network loss and offline transfer recovery are published capabilities.
Monitoring capacity
The official record specifies up to 280 monitored data points and up to 20,000 historical records.
Remote-access layer
Cloud 3.0, VNC, API and client alarm notifications support authorised remote workflows.
Connection architecture
Plan the mobile data path from HMI to authorised user
In addition to hardware compatibility, confirm the SIM, APN, carrier bands, user roles and cybersecurity rules.

Which connectivity scenarios suit the 4G Module?
Confirm local carrier coverage, frequency bands and the secure-access policy for every deployment.
Sites without wired networking
Machine locations where fixed Ethernet infrastructure is unavailable or impractical.
Remote machine monitoring
Selected operating data delivered to authorised users through Cloud 3.0.
Service and fault review
Controlled remote diagnostics through VNC or another project-approved access method.
Alarm and history tracking
Client notifications and historical records used together in maintenance and operations.
Official product and catalogue records
Use these manufacturer records to confirm model identity, lifecycle and the current document revision.
Answers to common selection questions
Short answers based on the official product and series records.
Which devices can use the module?
It is intended for compatible Samkoon HMIs; confirm the exact model and hardware revision before quotation.
Will it work on every local mobile network?
Band listings alone cannot provide that guarantee. Test the carrier, SIM, APN and regional band compatibility for the project.
What happens after a network interruption?
Automatic reconnection and offline transfer recovery are supported in the official technical record.
How much data can be monitored?
The official record specifies up to 280 data points and up to 20,000 historical records.
