Rakesh, Look in B0400BP IACC Users Guide Chapter 13 - Security. It describes how to setup user groups with various permissions. We have not used this feature, so I do not know how or if it will address your needs. Tom Badura Plastics Engineering Company tbadura@xxxxxxxxxx -----Original Message----- Subject: [foxboro] OPEN IACC IN READ ONLY MODE Hi there, The IACC software logic can be password protected but then that prevents somebody from seeing the logic also if he doesn't know the password. Is there any way, IACC software can be opened in Read Only Mode for a particular user ID so that one can only view the logic and not edit it.
