Setting the PLC Mode


Setting the operational mode of the Do-more controller or the Do-more Simulator within Do-more Designer is done through the Set PLC Mode dialog. This dialog will send a Mode change request to the controller. The controller will process the request and change to the specified mode as long as there are no issues that prevent it from happening, like errors in the project currently loaded in the controller or a problem with the hardware.

 

The Set PLC Mode utility can be opened by selecting PLC-> PLC Modes from the menu, or using the key sequence Ctrl+Shft+R, or clicking the Mode button on the Online toolbar

 

The Current PLC Status group displays:

 

  • PLC Mode: - displays the current operational mode: RUN or PROGRAM
     

  • PLC Mode Switch Position: - displays the current position of the mode switch located on the front of the controller: RUN, TERM, or STOP

 

The New PLC Mode group lists the operation modes that are available:
 

  • Run - the controller will execute the project in its memory
     

  • Program - the controller will stop executing the project in its memory

 


Click OK to send the Mode change request to the controller and close the dialog.

 

Click Cancel to close the dialog and leave the Mode unchanged.

 


The operational mode of the controller can only be changed from Do-more Designer if the controller's mode switch is in the TERM position. The Set PLC Mode dialog monitors the position of that switch and will only allow the mode change operation to take place when the switch is in the appropriate location.

 

If the controller's mode switch is in the RUN or STOP positions, the OK button will not be enabled. Follow this link for a detailed discussion of the controller's mode switch.
