Controller States and Behaviors Controller State Description RUN LED Err LED EMPTY There is no application present or an invalid application. Off 3 flash red EMPTY after detection of a System Error Details of the STOPPED State This state is the same as the normal EMPTY state except that a flag is set to make it appear as if no Boot Application is present (no Application is loaded) and the LED indications are different. Off Rapid flashing red RUNNING The controller is executing a valid application. Green Off RUNNING with Breakpoint RUNNING with detection of an External Error This state is the same as the RUNNING state with the following exceptions: The task-processing portion of the program does not resume until the breakpoint is cleared. The LED indications are different. For more information on breakpoints management, refer to the CoDeSys part of the SoMachine online help. This state is the same as the normal RUNNING state except the LED indications are different. STOPPED The controller has a valid application that is stopped. See Details of the STOPPED State (see page 50) for an explanation of the behavior of outputs and field buses in this state. STOPPED with detection of an External Error This state is the same as the normal STOPPED state except the LED indications are different. HALT The controller stops executing the application because it has detected an Application Error. This description is the same as for the STOPPED state with the following exceptions: The task responsible for the Application Error always behaves as if the Update IO while in stop option was not selected. All other tasks follow the actual setting. The LED indications are different Single flash green The following statements are always true for the STOPPED state: The input configured as the Run/Stop input remains operational. Serial (Modbus, ASCII, etc.), and USB communication services remain operational and commands written by these services can continue to affect the application, the controller state, and the memory variables. All outputs initially assume their configured state (Keep current values or Set all outputs to default) or the state dictated by output forcing if used. The subsequent state of the outputs depends on the value of the Update IO while in stop setting and on commands received from remote devices. 50 EIO0000000384 04/2012 Off Green Single flash red Flashing green Flashing green Flashing green Off Single flash red Red
Controller States and Behaviors Task and I/O Behavior When Update IO While In Stop Is Selected When the Update IO while in stop setting is selected: The Read Inputs operation continues normally. The physical inputs are read and then written to the %I input memory variables. The Task Processing operation is not executed. The Write Outputs operation continues. The %Q output memory variables are updated to reflect either the Keep current values configuration or the Set all outputs to default configuration, adjusted for any output forcing, and then written to the physical outputs. NOTE: if Q0, Q1, Q2 or Q3 outputs are configured for PTO, PWM, FG, or HSC operation, they fallback to a value of 0 irrespective of the configured fallback setting. For PTO operation, outputs Q0, Q1, Q2, and Q3 execute a fast stop deceleration. Outputs configured for PWM, FG, and HSC go immediately to 0. WARNING UNINTENDED EQUIPMENT OPERATION Design and program your system so that controlled equipment assumes a safe state when the controller enters fallback mode if you use outputs Q0, Q1, Q2, or Q3 for PTO, PWM, FG, or HSC operation. Failure to follow these instructions can result in death, serious injury, or equipment damage. NOTE: Commands received by Serial, USB, and CAN communications can continue to write to the memory variables. Changes to the %Q output memory variables are written to the physical outputs. CAN Behavior When Update IO While In Stop Is Selected The following is true for the CAN buses when the Update IO while in stop setting is selected: The CAN bus remains fully operational. Devices on the CAN bus continue to perceive the presence of a functional CAN Master. TPDO and RPDO continue to be exchanged. The optional SDO, if configured, continue to be exchanged. The Heartbeat and Node Guarding functions, if configured, continue to operate. If the Behaviour for outputs in Stop field is set to Keep current values, the TPDOs continue to be issued with the last actual values. If the Behaviour for outputs in Stop field is Set all outputs to default the last actual values are updated to the default values and subsequent TPDOs are issued with these default values.
