The primary task of SIWAREX CS is the measurement of sensor voltage and the conversion of this measurement into a weight value. Up to 3 interpolation points are used for the weight calculation. The signal can also be digitally filtered if required.

As well as determining weights, the SIWAREX CS monitors two freely programmable limits (min./max. as required) and notifies SIMATIC if these values are exceeded.

The SIWAREX CS comes factory-calibrated. This means that theoretical adjustment of the scale is possible without adjustment weights, and that modules can be replaced without the need to readjust the scale.

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

Reading of the process data from the SIWAREX CS via the distributed I/O is possible with all head modules. In the case of PROFIBUS head modules that support the DP V1 protocol and PROFINET head modules the data record communication can additionally be used for reading out the data and performing settings.

Group diagnostics and hardware interrupts are possible with all PROFIBUS head modules with DP V1 and PROFINET modules. Head modules with DP V0 support group diagnostics, but not the hardware interrupts.

The SIWAREX CS has two serial interfaces. The TTY interface serves to connect digital remote displays. The remote displays can show the weight value with status information.

To parameterize the SIWAREX CS, a PC can be connected over the RS 232 interface.

SIWAREX CS can be integrated in the plant software using the classic PLC programming languages; STL (Statement List), LD (Ladder Diagram) SFC (Sequential Function Chart) or SCL (Structured Control Language).

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

Used in conjunction with SIWAREX CS, it is possible to configure freely programmable, modular weighing systems in SIMATIC.

Scale faceplate in the SIWAREX CS "Getting started" software

In addition to the configuration package, the ready-made SIWAREX CS "Getting started" software is available free-of-charge and shows beginners how to integrate the module into a STEP 7 program and offers a basis for application programming. This allows you to implement the scale very easily with an operator panel connected directly to the SIMATIC CPU.

Using the SIWATOOL CS software, the SIWAREX weighing modules offer Windows convenience and are quick to get into operation. Screen forms allow all user-definable parameters of the weighing modules to be specified, saved and printed for plant documentation.

The diverse diagnostics options provided by SIWATOOL CS ensure fast fault locating in online mode.

The SIWAREX CS weighing module can be used in potentially explosive areas (zone 2). Zone 1 - It can also be used in zone 1 by implementing an optional Ex interface, whereby SIWAREX CS must be installed in a safe area.
