Modbus FAQ for Automation Engineers

Modbus is a widely used communication protocol in industrial automation. It enables different devices, such as PLCs, sensors, drives, and precision tools like Kolver’s K-DUCER, to exchange data over serial or Ethernet connections.

For automation engineers, Modbus is almost plug-and-play: most Ethernet-capable PLCs and industrial PCs/MES systems already support it.

Factory Certification vs Accredia: What’s the Real Difference?

When it comes to tightening tools, precision isn’t optional — it’s a requirement.
But how can we be sure that a screwdriver or torque tester truly meets the required standards?
The answer lies in certification. But beware: not all certifications are created equal.

K-TESTER + DOCK08 1

New multiple output connector for K-TESTER

In the field of industrial assembly, the reliability and accuracy of torque tools are essential.

KOLVER’s K-TESTER is already a leading tool for torque measuring, but what happens when multiple transducers are involved, and a real-time, streamlined solution is needed?

The answer is the new multiple output connector DOCK08, which allows up to 4 transducers to be connected simultaneously to the K-TESTER.

Washers, Embedding, and Bolt Relaxation: what’s really going on in your assembly

In bolted joints, the use of washers has become something of a default practice. At first glance, a washer seems like a simple component, just a flat disc placed between the nut or bolt head and the joint surface, but underneath this simplicity lies a complex interplay of mechanics and materials that can make or break the performance of your assembly over time.

Let's then take a look at why washers are used, how they impact bolt relaxation, and why the phenomenon of embedding, frequently underestimated, deserves special attention in joint design.
