Hello. I try to develop my own FB to work with WP321 in TIA Portal V14. I have carefully read Manual - Electronic weighing system SIWAREX WP321, but this manual describes more working with WP321 via FB321 (block from application "ready to use" developed by Siemens). For example, structures for all data records are described in this manual, but how send command ("Service mode On/Off", "Set Calibration Point 0", "Set Calibration Point 1" and etc.) via DR02 isn't described. I have done some experiments with FB321 and have seen that DR02 is sent to WP321 via it output interface, for all other data records block uses "WRREC" instruction. Also Siemens makes that process variable (weight, ADC and etc.) can be directly read from input interface. For example, with DR14 you can assign process value 1, 2 and after that read them from IDx+8, IDx+12. Does anybody have description of WP321 I/O interface, and sequence how send commands for calibration, which signals must send back WP321 and so on? Thank you. |

Hello anbron, On the internet you can find also a “small” FB321 with a shorten Instance-DB to spare space in the S7-program. There exist a “Ready-for-use-small” project for TIA Portal and for Simatic Manager: https://support.industry.siemens.com/cs/ww/en/view/94109373 Best regards Siwarexi |
