Commanding State Transitions<br />
Run Command<br />
Stop Command<br />
Effect: Commands a transition to the RUNNING controller state.<br />
Starting Conditions: BOOTING or STOPPED state.<br />
Controller States and Behaviors<br />
Methods for Issuing a Run Command:<br />
Run/Stop Input: If configured, command a rising edge to the Run/Stop input. The<br />
Run/Stop input must be 1 for all of the subsequent options to be effective.<br />
Refer to Run/Stop Input (see page 79) for more information.<br />
SoMachine Online Menu: Select the Start command.<br />
By an external call via Modbus request using the PLC_W. q_wPLCControl and<br />
PLC_W. q_uiOpenPLCControl system variables of the <strong>M238</strong> PLCSystem Library<br />
(see Modicon <strong>M238</strong> Logic Controller, System Functions and Variables, <strong>M238</strong><br />
PLCSystem Library Guide).<br />
Login with online change option: An online change (partial download) initiated<br />
while the controller is in the RUNNING state returns the controller to the<br />
RUNNING state if successful.<br />
Multiple Download Command: sets the controllers into the RUNNING state if the<br />
Start all applications after download or online change option is selected,<br />
irrespective of whether the targeted controllers were initially in the RUNNING,<br />
STOPPED, HALT or EMPTY state.<br />
The controller is restarted into the RUNNING state automatically under certain<br />
conditions.<br />
Refer to Controller State Diagram (see page 44) for further details.<br />
Effect: Commands a transition to the STOPPED controller state.<br />
Starting Conditions: BOOTING, EMPTY or RUNNING state.<br />
Methods for Issuing a Stop Command:<br />
Run/Stop Input: If configured, command a value of 0 to the Run/Stop input. Refer<br />
to Run/Stop Input (see page 79) for more information.<br />
SoMachine Online Menu: Select the Stop command.<br />
By an internal call by the application or an external call via Modbus request using<br />
the PLC_W. q_wPLCControl and PLC_W. q_uiOpenPLCControl system<br />
variables of the <strong>M238</strong> PLCSystem Library (see Modicon <strong>M238</strong> Logic Controller,<br />
System Functions and Variables, <strong>M238</strong> PLCSystem Library Guide).<br />
Login with online change option: An online change (partial download) initiated<br />
while the controller is in the STOPPED state returns the controller to the<br />
STOPPED state if successful.<br />
Download Command: implicitly sets the controller into the STOPPED state.<br />
