Simple wiring in the control cabinet


Siemens has broadened its Simatic Top Connect portfolio with a range of new modules and system components for fast and safe wiring of Simatic S7-1500 and Simatic ET 200MP.

In addition to connection modules for eight channels (inputs or outputs), Siemens also offers, for the first time, compact versions for 32 channels that are available for connecting sensors and actuators via one or three wires.

Siemens has broadened its Simatic Top Connect portfolio with a range of new modules and system components for fast and safe wiring of Simatic S7-1500 and Simatic ET 200MP. With system cabling, users can save up to 80 percent time compared to conventional single wiring using terminal blocks.

Thereby only one cable needs to be connected between the connection module and the S7-1500 controller instead of four for the individual 8-channel modules. In addition, the new 32-channel connection module requires less space on the mounting rail than four modules with eight inputs and outputs each. The new connection modules feature the compact design of the Simatic S7-1500, allowing space-saving installation in the control cabinet. With system cabling, users can save up to 80 percent time compared to conventional single wiring using terminal blocks.

The connection modules with eight channels are available in different versions, with disconnect terminals for manually cutting off specific plant sections, for example, or with relays and optocouplers for adapting the potential with which signals with AC voltages of 110 or 230 volts can also be connected to the controller. The 8-channel connection modules are fully compatible with the field-proven front connector modules for Simatic S7-300 and ET 200 M.

The appropriate system cabling can be selected in accordance with the respective input or output modules simply and quickly in the TIA Selection Tool.

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...

Im Focus: Laser process simulation available as app for first time

In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.

Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
