Scale meets SIMATIC Advanced
Controllers
Ready for the new SIMATIC generation: The SIWAREX
WP521 ST and WP522 ST are the first dedicated weighing
modules for the SIMATIC S7-1500 Advanced Controllers. The
two technology modules are the perfect solution for the
seamless integration of standard weighing applications like
platform or hopper scales in SIMATIC S7-1500. They offer
numerous advantages:
Versatile
The technology module is available in single and dualchannel variants. SIWAREX WP521 ST is the single-channel
option for one scale while the dual-channel SIWAREX
WP522 ST enables two separate scales to be integrated into
the automation system - with same space requirements.
Connectivity
The seamless integration of the weighing electronics enables you to exploit all the benefits of the automation
system. Fast, safe communications via the CPU system bus
and the integrated hardware design are just two of these
highlights. SIWAREX WP521 ST and WP522 ST are also easy
to integrate in third-party systems. A variety of interfaces is
available on board: Modbus TCP/IP (Ethernet), Modbus RTU
(RS 485), as well as four digital outputs and three digital
inputs.
The factory provided shielding set guarantees an integrated, optimal wiring regarding immunity to interferences on
the load cell cable.
User friendliness
Thanks to the function block and the “Ready for use” example project, integrating the scales into the automation
system is child’s play. Complete commissioning, parameter
assignment and operator control of the scales are all possible from a central machine HMI. This enables the scale’s
user interface to be adjusted to suit the machine interface,
facilitating a uniform, system-wide operating concept.
The weighing modules are easy to configure, even without
the need for SIMATIC expertise: With the SIWATOOL V7 PC
software, it’s simple to access all parameters and functions.
SIWAREX WP521 ST and WP522 ST can also be put into
operation and serviced remotely using SIWATOOL V7. On
top the Ethernet interface enables problem-free integration
into the plant network.
Process quality and safety
Impedance monitoring of the load cells as well as a range
of hardware and diagnostic interrupts ensure enhanced
plant availability and process safety.
With a measuring rate of 100/120Hz and high resolution up
to +/- four million parts, weighing is fast and highly accurate with the SIWAREX WP521 ST and WP522 ST.
