SIWAREX U is available with either one or two measuring channels. One measuring channel is required for each set of scales.

The primary task of SIWAREX U is the measurement of sensor voltage and the conversion of this measurement into a weight value. The signal can also be digitally filtered if required. As well as determining weights, it monitors two freely programmable limits (min./max. as required).

The SIWAREX U comes factory-calibrated. This means that we can theoretically adjust the scale without using adjustment weights, and we can replace modules without having to readjust the scale. When using "active bus modules", replacement is also possible during operation.

Consistent and uniform communication between all system components enables fast, reliable and cost-effective integration and diagnosis in industrial processes.

The SIWAREX U has two serial interfaces. The TTY interface serves to connect up to four digital remote displays. In addition to the two weight values of weighing channels 1 and 2, another two values can be set via SIMATIC and indicated on the remote displays.

Functions

A PC for adjusting the scale can be connected through the RS 232 interface.

Engineers can integrate SIWAREX U in the plant software not just with the classic PLC programming languages like STL (Statement List), LD (Ladder Diagram), SFC (Sequential Function Chart) or SCL (Structured Control Language). Additionally, you can integrate it through graphical configuration using CFCs (Continuous Function Chart). Here, PCS 7 provides faceplates for visualizing the scales.

In contrast to serially linked weighing electronics, SIWAREX U does not need costly additional modules to link it to SIMATIC.

Integrating in SIMATIC enables us to create freely - programmable, modular weighing systems. We can modify these systems according to operational requirements.

Using the SIWATOOL U software, the SIWAREX weighing modules can be set up with the convenience of Windows independently of the automation system. Engineers can use input masks to specify all parameters for the weighing modules, save them, and print them for plant documentation.
