Hello Automation_Systems, You are using ET200s AI 2-wire (4gb00), meaning that the Card is providing voltage to sensor, to generate 4-20 mA signal. See manual: http://support.automation.siemens.com/WW/view/en/25545977 Perhaps you need ET200s AI 4-wire (4gb11), meaning that the sensor has it's own supply voltage. See manual: http://support.automation.siemens.com/WW/view/en/25545991 Hope this helps. Best regards, Wizard |
