Reaching a Machine in the Field — Today, and with Simplinx
- A fault call comes in, the service engineer travels — and the machine waits
- Or a PC with every program installed is left on site, with its own licences, updates and upkeep
- Remote access means negotiating a VPN and firewall rules with the customer's IT
- No clear record of who connected, and when
- One small device in the panel; on site, all it needs is internet
- The programs stay on the engineer's own laptop — no PC goes to site
- The customer's IT is not asked to open a port or set up a VPN
- Only the people you authorise can connect, and every connection is logged
Four Steps. No IT Expertise Needed.
SMX-RNS20 clips onto the DIN rail and runs from the panel's 24V supply.
The PLC and the operator panel plug into the device's two machine ports.
The device is prepared in your factory and travels to site inside the machine.
On site, an internet cable goes in — Wi-Fi or a phone's connection also work. That is all.
When the Service Call Comes In
The machine has stopped and there is an alarm on the operator panel.
Signs in to simplinx.net, picks the customer's machine and connects in one click. Their own tools, TIA Portal for example, see the PLC as if it were on the desk.
The operator panel's screen opens in the phone's browser — no app to install.
Corrects the program, downloads it, restarts the machine. No travel, and the machine is down for less time.
No IT. No Firewall Changes.
No Subscription.
SMX-RNS20 ships pre-configured in your machine cabinet. Your customer plugs in one ethernet cable. Your engineer opens SX-Client, selects the device, and is connected — in under a minute. No ports to open, no VPN server to manage, no IT approval to chase. The P2P DTLS tunnel goes outbound over TCP 443, which every corporate firewall already allows.
- P2P encrypted tunnel — machine data never passes through Simplinx servers
- Works over Ethernet, USB Wi-Fi adapter, or phone tethering
- Multi-user access — each engineer gets their own certificate, revocable individually
- Slave License: define exactly which devices each sub-user can see and connect to
- Any browser, nothing to install — reach HMI screens (VNC) and web interfaces (HTTP/HTTPS) via simplinx.net from a laptop or phone
- One-time device purchase — no annual licence, no cloud fee
PLC Data — Without a Separate Gateway
SX-IO runs directly on the SMX-RNS20 — no additional hardware required. Connect to the machine's PLC, HMI, or drives and start collecting process variables via 13 protocol drivers simultaneously. Data is stored locally in an onboard historian and evaluated for alarm conditions in real time.
- 13 protocol drivers — Modbus TCP/RTU, OPC-UA, S7, EtherNet/IP, BACnet/IP, OMRON FINS, SNMP, Serial and more
- On-device alarm evaluation — email and SMS alerts without cloud round-trip
- 2 GB local storage — historian data survives connectivity loss
- No separate data gateway or edge PC required
Push Machine Data to Any Cloud — No Middleware
SX-IO sends collected data directly to AWS IoT, Microsoft Azure IoT Hub, Google Cloud, or any MQTT broker — on your schedule, without an on-premise server or integration middleware. You can also push directly into SQL databases (PostgreSQL, MySQL, MS SQL) for your own dashboards and analytics.
- Native connectors: AWS IoT, Azure IoT Hub, Google Cloud, MQTT
- Direct SQL push: PostgreSQL, MySQL, MS SQL Server
- Configurable push interval — from seconds to hours
- Buffered locally during connectivity loss, flushed on reconnect
Your Machine Talks Only to Who You Allow
In Bridge Mode, SMX-RNS20 places your machine in its own isolated segment. The factory office network cannot initiate connections to the machine. Only explicitly permitted devices can reach specific ports — for example, the SCADA server on port 80, or a historian on Modbus port 502. All other traffic is blocked by default.
- Machine cannot reach the office network — zero lateral exposure
- Port-level rules: only permitted source IP → permitted port is allowed
- Works without modifying PLC or HMI configuration
- Compatible with GTW10 for additional OT/IT boundary enforcement
CE File Ready — Out of the Box
EU Machinery Regulation 2023/1230 requires cybersecurity documentation for remote access components in CE-marked machines. SMX-RNS20 ships with a complete documentation package — ready to drop into your machine's technical file without additional assessment work.
- Declaration of Conformity — signed and current
- Cybersecurity Statement — architecture, encryption, key management
- Risk Assessment — remote access threat model for your CE file
- Available in English and Turkish
Industrial Cybersecurity Certification — In Progress
ISA/IEC 62443 is the international standard for industrial cybersecurity. Machine builders are increasingly required to demonstrate compliance by Tier 1 manufacturers, system integrators, and procurement teams.
SMX-RNS20 is on a structured path to ISA/IEC 62443 compliance. Secure development lifecycle (4-1) and independent product assessment (4-2) are underway — targeted for 2026.
Our development processes are being assessed against ISA/IEC 62443-4-1 secure product development lifecycle requirements.
SMX-RNS20 is undergoing independent assessment against ISA/IEC 62443-4-2 technical security requirements for IACS components.
