    1. Hardware Requirements Following hardware parts and software are requested to integrate a scale into SIMATIC S7-200: SIWAREX MS module, 24V Power Module, S7-200 CPU, SIWATOOL MS configuration package, RS232 cable, computer with Windows XP or higher and a calibration weight bigger than 5% of the sum of the nominal value of all load cells.

  • Page 9: Adjustment With An Adjustment Weight

    - the parameter “Numeral step” (index card “Scales parameter”) is set to “1”. - the parameter “Decimal point” (index card “Scales parameter”) is set to “2”. - the parameter “Weight unit” (index card “Scales parameter”) is set to “kg”. ©Siemens AG SIWAREX_MS_Quick Guide_V4.0.doc, 12/2010...

    The weight is measured according to the average value of n weight values. If n = 10, 10 weight values will be used for calculating the average value. The earliest value is discarded every 20 milliseconds and the latest value will be added for the calculation. ©Siemens AG SIWAREX_MS_Quick Guide_V4.0.doc, 12/2010...

    The zeroing range is between -20 kg (-1% of 2000) and +60 kg (+3% of 2000). Zeroing will be rejected if the current gross weight is too high or too low. After setting the parameters, click Send to send the changed parameters to the Siwarex MS module: ©Siemens AG SIWAREX_MS_Quick Guide_V4.0.doc, 12/2010...

  • Page 12: Adjustment Procedure

    Ensure that the scale is empty (not loaded) and execute the command Adjustment zero valid (3). The Siwarex MS module shows now the weight value “0”. 7 Calibration Procedure Ensure that the scale is empty (not loaded) and click Adjustment zero valid (3).

    Afterwards, place the adjustment weight on the scale and execute the command Adjustment weight 1 valid (4). With executing of this command, the adjustment line is detected of the scale. The Siwarex MS module shows now the adjustment weight. Adjustment Weight The adjustment is completed now.

  • Page 14: Adjustment Without An Adjustment Weight (theoretical Adjustment)

    The execution of the theoretical adjustment is handled with the help of the SIWATOOL MS software. First, the "Characteristic value" (e.g. “2 mV/V”) must be defined in the DR3, index card: "Calibration": ©Siemens AG SIWAREX_MS_Quick Guide_V4.0.doc, 12/2010...

    (See also step “2.” and “3.” in the picture below) These values are taken from the respective load cell measuring log. If the measuring logs aren’t available, the default-values can be used, e.g. “Zero offset in uV/V” = “0” and “Characteristic value” = “2.0”: ©Siemens AG SIWAREX_MS_Quick Guide_V4.0.doc, 12/2010...

    Then, the calculated adjustment digits can be integrated into the DR3 by actuating the button "Accept calculation": The DR3 is then sent to the weight module with the new adjustment data with the button "Send": ©Siemens AG SIWAREX_MS_Quick Guide_V4.0.doc, 12/2010...

  • Page 17

    After sending the DR3, the command “Characteristic curve shift (15)" has to be executed, when the scale is empty. The theoretical adjustment is now finished. ©Siemens AG SIWAREX_MS_Quick Guide_V4.0.doc, 12/2010...
