Chapter 1 Introduction NOTE 1) The controller should provide RS-485 interface. 2) Off-line/On-line simulation functions are only provided for some parts of the controllers. Also, the execution time of on-line simulation only can continue 30 minutes. After the simulation time has finished, HMI will return to the main screen of Screen Editor V2.0 software program from simulation window automatically. 3) When executing simulation function, the resolution of PC screen should be set to 24bit and higher, otherwise the simulation function may not work normally.
