S7-200 214 unknown trim control

[markaren1 0]

Hi Guys, The top of the units appears to have two small recessed trimmers marked '0' and '1', any idea what they are for ? I am also looking for a copy of the manual for the 214 unit, I can only find more recent manuals. Pointers to where go hunting will be appreciated. Thanks, Mark

The potentiometers control the value of two special memory bytes. The values in these memory locations could then be used to create adjustable timers, speed command setpoints, etc. Sorry, but I do not have a manual to tell which bytes the pots control. Here is a link to the manuals on the Siemens site: http://www.sea.siemens.com/us/Products/Automation/Micro-Automation/support/Manuals/Pages/S7-200Manuals.aspx Edited 21 Oct 2010 by drforsythe
