SettingSimDm1 Setting this variable to 1 will turn DM1 simulation on; 0 will turn it off.When DM1 simulation is on, the display will periodically generate a DM1 fault or multiple faults.How the DM1 fault information is displayed depends on the configuration (see the Diagnostic Messages application).SettingSimDm2 Setting this variable to 1 will turn DM2 simulation on; 0 will turn it off.When DM2 simulation is on, the display will generate a DM2 fault or multiple faults in response to a DM2 fault request.Basically, the display will respond to its own request for faults (instead of an external device).How the DM2 fault information is displayed depends on the configuration (see the Diagnostic Messages application).
