The MQTT.box is your broker solution

The MQTT.box from Wiesemann & Theis (W&T) is a Mosquitto MQTT broker for DIN rail mounting. It can operate as a standalone Mosquitto MQTT broker in the network and enables secure communication between network-capable automation components using MQTT protocol. The unique feature of MQTT is that two communication partners exchanging data with each other never […]

Monitor levels with the Web-IO Analog-In

Gather, monitor and archive analog measurement values over the Internet/Intranet. The Web-IO Analog lets you access analog current and voltage signals over Ethernet. Depending on the model the devices monitor and set 0/4-20mA or 0-10V signals per DIN IEC 60381-1 And -2. Application example, how does it work:  Definition of tasks: In a production environment […]

USB memory with network connection

The German IT manufacturer W&T added another interesting new product to their product range, the transfer.box LAN-USB, which can both store data and send it from USB devices over the Internet. The transfer.box is a USB memory with network interface. Whereas locally connected USB sticks or USB drives are a “dead-end street” in terms of […]

IT and OT – secure free spaces

IT security for operative technologies. Industrial manufacturing is based on the pillars of information and operational technology: in short, IT and OT. IT tasks include data processing and strategic planning of production on the company level, whereas OT handles specific control of the individual production lines and equipment. Both areas work towards the same company […]

Switching by phone call – Thanks to VolP and SIP

Open gates or doors remotely? Trigger alarms by switching signal lamps, horns, bells or sirens? Control outdoor lighting? All it takes is a phone call.   Voice-Over-IP Voice-Over-IP has been an established communication standard for years. The advantage of this technology is that telephones, PCs and other terminal devices can operate in one and the […]

Web-IOs now also with OPC UA

The Web-IO range from Wiesemann & Theis (W&T) now supports OPC UA, one of the most essential common communication standards. Now Web-IOs can make even older machines, controllers and measuring devices viable for the future. That’s a great benefit! The Web-IOs allow traditional automation components and various measuring points to communicate with any other machine, […]

Segmentation: Router- vs. Bridge Mode

Bridge: Microwall Bridge The Microwall Bridge operates transparently as far as the IP ranges are concerned. This means the IP ranges (Net-IDs) of the surrounding network and the island side are identical. Nevertheless, cross-network connections are only possible after establishing express release rules based on the respective involved IP addresses and TCP/UDP port numbers. Preferred […]

Protecting machines and equipment without changing the IP setup

The Microwall Bridge (Firewall) provides security when needed, quickly and simply and this without changing the IP configuration. The preferred area of application is therefore the easiest possible, add-on security expansion of existing infrastructures. Segmenting network and isolating of sensitive network areas is one of the basic measures in virtually any IP security concept for […]

Network one-way street

The Fix Defined Firewall links computers to networks with no feedback, so that the computers are able to receive only. All received network packets are passed on in one direction to the reading host. Data traffic to the safe network is not possible – neither from the reading computer nor from the firewall itself. How […]

Reliably transmit switching signals over long distances

The Digital-I/O Extender Set 2×2 transmits up to four digital I/O signals over multi-mode glass fibre cable. The Set consists of two Converters Digital-I/O <> glass fibre optics and supports two I/O channels in each direction. BUY online… Although digital I/O signals are essentially insensitive to external noise due to their low bandwidth and the […]
