SIMATIC S7-1200 or Stand Alone, SIWAREX WP231, single-channel legal-for-trade weighing module for platform or hopper scales with analog load cells / strain gauges (full bridges), 4xDI, 4xDQ, 1xAQ, 1xRS485, 1xEthernet, 1xLC load cell interface (1-4mV/V)), attention: for legal-for-trade applications please follow the local laws applying in the country of verification! Detailed load cell diagnostics with digital junction box SIWAREX DB (7MH5001-0AD20 or 7MH5001-0AD01)
Q: Can I use this with an S7-1500 PLC?A: The WP231 is physically designed for the S7-1200. For S7-1500, you should look for the SIWAREX WP321 (7MH4950-2AA01) which fits the S7-1500 rail.
Q: How many load cells can I connect?A: You can connect up to 12 load cells (each 1000 Ohm) in parallel using a junction box.
Q: Is there a software required for calibration?A: You can calibrate it using the SIWATOOL V7 software or directly through a SIMATIC HMI panel or the module's web server.
