I m in need of Beckhoff TwinCAT TcRFID.lib Library, if anyone knows from where to download it, please reply immediately

 

That library appears to be a part of the Twincat software package - http://infosys.beckhoff.com/english.php?content=../content/1033/tcplclibrfid/html/tcrfid_readerhardware.htm&id=

That being the case, have you contacted Beckhoff? We can't let members trade illegal software.
