Controller States and Behaviors UNINTENDED EQUIPMENT OPERATION WARNING You must have a thorough understanding of how forcing will affect the outputs relative to the tasks being executed. Do not attempt to force I/O that is containted in tasks that you are not certain will be executed in a timely manner, unless your intent is for the forcing to take affect at the next execution of the task whenever that may be. If you force an output and there is no apparent affect on the physical output, do not exit SoMachine without removing the forcing. Failure to follow these instructions can result in death, serious injury, or equipment damage. 56 EIO0000000384 04/2012
Commanding State Transitions Run Command Stop Command Effect: Commands a transition to the RUNNING controller state. Starting Conditions: BOOTING or STOPPED state. Controller States and Behaviors Methods for Issuing a Run Command: Run/Stop Input: If configured, command a rising edge to the Run/Stop input. The Run/Stop input must be 1 for all of the subsequent options to be effective. Refer to Run/Stop Input (see page 79) for more information. SoMachine Online Menu: Select the Start command. By an external call via Modbus request using the PLC_W. q_wPLCControl and PLC_W. q_uiOpenPLCControl system variables of the M238 PLCSystem Library (see Modicon M238 Logic Controller, System Functions and Variables, M238 PLCSystem Library Guide). Login with online change option: An online change (partial download) initiated while the controller is in the RUNNING state returns the controller to the RUNNING state if successful. Multiple Download Command: sets the controllers into the RUNNING state if the Start all applications after download or online change option is selected, irrespective of whether the targeted controllers were initially in the RUNNING, STOPPED, HALT or EMPTY state. The controller is restarted into the RUNNING state automatically under certain conditions. Refer to Controller State Diagram (see page 44) for further details. Effect: Commands a transition to the STOPPED controller state. Starting Conditions: BOOTING, EMPTY or RUNNING state. Methods for Issuing a Stop Command: Run/Stop Input: If configured, command a value of 0 to the Run/Stop input. Refer to Run/Stop Input (see page 79) for more information. SoMachine Online Menu: Select the Stop command. By an internal call by the application or an external call via Modbus request using the PLC_W. q_wPLCControl and PLC_W. q_uiOpenPLCControl system variables of the M238 PLCSystem Library (see Modicon M238 Logic Controller, System Functions and Variables, M238 PLCSystem Library Guide). Login with online change option: An online change (partial download) initiated while the controller is in the STOPPED state returns the controller to the STOPPED state if successful. Download Command: implicitly sets the controller into the STOPPED state. EIO0000000384 04/2012 57
