AndreyG Posts: 25 Rating: (0)	Ok, I thunk I got it now. LOGO! 12/24RCo 6ED1 052-2MD00-0BA6 I believe they do have 4 analog inputs and the inputs AI3 and AI4 are instead of I1 and I2. Is this correct?

The input mode is defined in the LOGO! circuit program. The inputs I1, I2, I7 and I8 provide digital inputs, and the inputs AI3, AI4, AI1 and AI2 provide analog inputs, as described in the topic "Constants and connectors - Co (Page 138)". AI3 corresponds to the input terminal I1; AI4 corresponds to I2; AI1 corresponds to I7; AI2 corresponds to I8. The use of AI3 and AI4 is optional. You configure your LOGO! to use either two or four analog inputs as described in topic "Setting the number of AIs in the LOGO! Basic (Page 299)" in Section 5.2.4. When using inputs I1, I2, I7 and I8 as analog inputs, only the range from 0 to 10 V DC is available. You can find manual [url=http://support.automation.siemens.com/WW/view/en/50074616] here [/url] Regards, Marcjan
