2. This manual also forms Part One of the reference manual for TRLOGI Version 4 1 which is used for programming the powerful M series PLCs TRILOGI Version 4 1 fully supports all the features of the ladder logic editor compiler and simulator described in this manual In addition Version 4 1 supports the TBASIC programming language for handling data processing jobs and_ for programming the many special peripherals of the M series PLC You will find that TRLOGI Version 4 1 provides more selection items in its pull down and pop up menus than Version 3 3 and 3 3E These differences have been documented in Chapter 1 of the Programmer s Reference Part Two manual The TBASC Reference You may refer to this document for a comparison between Version 3 3 and Version 4 0 ll Installing TRILOGI in Your Computer TRILOGI Version 3 3 3 3E and Version 4 1 are all MS DOS programs Although the program can run in a MS DOS prompt box under Windows for editing and simulating the ladder or Ladder BASIC programs it is best to run the program under pure DOS environment to achieve enor free communication with the PLC This is because TRILOGI accesses the PC s serial port directly instead of making API calls to Windows and if Windows switches task to other programs TRILOGI will tend to lose some incoming characters from the serial port resulting in frequent Communication Eror or other stange enor messages This however does not affect pro
