Translation from the chinese text (Thanks to Google Translate):
Hello 气力输送; 参加西门子论坛的成员来自许多国家,许多人不会说中文。 我们选择英语作为国际语言,以使交流更清晰。 请在下次访问时用英文写信给我们。 Hello 气力输送 (Pneumatic Conveying): Members participating on the Siemens forum come from many countries, and many do not speak Chinese. We have selected English as an international language to make exchanges clearer. Please write to us in English on your next visit. As to your problem: how many channels are you using with this analog module, and what type of measurement are you attempting to connect to your sensors? The results you see will happen if you do not wire or set up the module properly for the type of measurement you plan to do (voltage, current, RTD, Thermocouple) and if you do not adjust the measuring range module on the side of the analog module case. You should take the time to review the wiring you have done based on the schematics provided in the S7-300 Module Data manual, ch. 6, Analog modules, Section 6.7.Make sure that the Mana pin is well connected to functional ground, as shown. Also ensure that the parameters of each channel are correctly set (through the HWCofig editor for your analog module). The screenshot below shows the wiring schematics for Voltage and Current measurements. https://support.industry.siemens.com/cs/ww/en/view/8859629 If it is helpful, the manual can be downloaded in various languages, including Chinese; you can select the download language through the "Language" link at the top of the download page. Hope this helps, |
