Industrial remote access and maintenance guides
Practical guides to help you choose a remote-access architecture, prepare maintenance work and use the right protocols without redesigning the customer’s network.
Access a PLC remotely without using the customer’s Internet connection
Remote PLC maintenance is common, but relying on the customer’s Internet connection is not always possible. A locked-down firewall, strict IT policy, undocumented network or no fixed Internet access can make connectivity harder than the PLC itself.

One more SIM card does not look complicated. Ten, twenty or fifty sites later, subscriptions, data plans, renewals and operator portals can become a real management burden.
Read the guide →CYBERSECURITYRemote maintenance security: why removing access is the strongest protection
A remote path that is unavailable outside interventions dramatically reduces the attack surface. On-demand access combines conventional security controls with the absence of unnecessary permanent exposure.
Read the guide →NETWORKIndustrial VPN: which solution for occasional maintenance?
VPNs are a standard way to reach a remote network. But when an intervention lasts only minutes or hours, maintaining a permanent VPN infrastructure can be disproportionate. The right model depends mainly on access frequency and the level of integration required.
Read the guide →COMPARISONEwon, IXON, 4G router or RescueLAN: what are the differences?
All of these solutions can provide industrial remote access, but they are designed for different use cases. The right architecture depends on access frequency, expected services and the network available on site.
Read the guide →AUTOMATIONRemote CODESYS access: how to work on a PLC remotely?
CODESYS is used to program and diagnose many PLCs and controllers. Remotely, the main challenge is usually not CODESYS itself but providing a controlled network path from the engineering workstation to the controller.
Read the guide →MAINTENANCERemote maintenance without a subscription: when does it make sense?
A monthly subscription makes sense when a remote service is used continuously. But many industrial assets need only one or two remote maintenance sessions per year. In that case, paying for actual usage rather than permanent availability can make more sense.
Read the guide →4G / LTEWhy use an independent 4G connection for industrial maintenance?
In industrial maintenance, connectivity is often the least predictable part of the job. An independent 4G/LTE connection avoids making maintenance access depend on the site router, firewall or IT policy.
Read the guide →HTTP / HTTPSAccess an industrial Web interface remotely
PLCs, HMIs, drives, gateways, technical cameras and building-management equipment often provide a local Web interface. Remote access is useful for diagnostics, provided the interface is not published directly on the Internet.
Read the guide →PROTOCOLSRDP, VNC or SSH: which remote access should you use?
RDP, VNC and SSH all support remote access, but they serve different needs. The right protocol depends on the equipment, operating system and what the technician actually needs to do.
