Posted 19 Oct 2006 Hello All A customer of mine need me to modify a machine on site that I did not originally build. He has sent me the PLC and HMI files - the HMI file has an extension of .prw - Anyone know what brand HMI this might be? Share this post Link to post Share on other sites
Posted 20 Oct 2006 I believe that is a Pro-Face HMI extension. http://www.pro-face.com/ Share this post Link to post Share on other sites
