DatasheetSIWAREX WP521 ST and WP522 ST are technology modules for the SIMATIC S7-1500 advanced controller family: SIWAREX WP521 ST is the single channel option for the set-up of one scale and SIWAREX WP522 ST is the two-channel option for the set-up of two independent scales. Integrated in SIMATIC S7-1500 all advantages of the automation system can be used. The free “ready-for-use“ application helps to create fast and easily customer and application specific solutions. Besides that, the service software SIWATOOL V7 enables a quick and user-friendly. The integrated monitoring function of the load cells impedance as well as the process and diagnosis alarm functions optimize the plant security resp. plant availability.
