SIEMENS TM SIWAREX WP341 HF WEIGHING ELECTRONICS

SIEMENS SIWAREX WP241 WEIGHING ELECTRONICS

SIEMENS TM SIWAREX WP341 HF WEIGHING ELECTRONICS

The SIWAREX WP341 is a compact and precise weighing electronics designed in the SIMATIC ET 200SP format. Remarkably slim at just 20 mm wide, it stands as one of the slimmest weighing electronics available. Despite its compact size, its firmware encompasses the functionalities of continuous belt weighing electronics. Additionally, the WP341 offers the option to operate solids flowmeters. By directly connecting the load cells and the speed sensor to the ET 200SP Base Unit (type U0), the entire system seamlessly integrates into the automation system.

Application

SIWAREX WP341 offers a compact and extremely versatile solution for continuous belt weighing applications with high requirements for accuracy and performance.

Typical areas of application include:

Belt weighers in recycling, mining, aggregate, cement, chemical and food industries
Easy and completely integrated realization of weigh feeding applications
Operation with solids flowmeters

Design

The SIWAREX WP341 is a technology module of the SIMATIC ET 200SP distributed I/O system.

Installation is on a type U0 BaseUnit. The load cells, serial RS 485 interface and digital inputs/outputs are wired directly on the BaseUnit with user-friendly push-in terminals. This makes is quick and easy to replace weighing electronics without any wiring effort.

The web server is addressed via an Ethernet interface in the weighing electronics. Should more interfaces and I/O be required, they can be added with the ET 200SP system components.

Application

SIWAREX WP241 is the optimal solution wherever belt scales are used that demand high accuracy, high user-friendliness, and flexible system integration. The typical applications of the SIWAREX WP241 are determining the current material flow rate, belt load, and belt speed. Furthermore, 6 totalizers are available for evaluating the amount of material conveyed.

Design

SIWAREX WP241 is a compact technology module in the SIMATIC S7-1200, and it allows direct connection to S7-1200 components via a sliding connector. The rail mounting of the 70 mm (2.76 inch) wide weighing module means that it is extremely easy to mount/wire.

The power supply, load cells, RS 485 interface, digital input/outputs and the analog output are connected via the screw plug of the weighing module. An RJ45 plug is used for the Ethernet connection.

Benefits

Uniform design technology and consistent communication in SIMATIC S7?1200
Uniform configuration with TIA Portal
Operation without SIMATIC CPU possible
Direct connection of an operator panel via Ethernet
Four digital inputs and outputs, one analog output
Measurement of weight with a high resolution of ± 4 million parts
Simple adjustment of belt scales using the SIWATOOL V7 program via the Ethernet interface - even without knowledge of SIMATIC
Replacement of module possible without renewed calibration of the scale
Use in hazardous area zone 2
Different calibration methods: With test weights, test chain, automatically or via material batch.
Specification of belt inclination angle
6 totalization memories
Simulation of speed and belt load for test purposes
Comprehensive diagnostics functions
