Controller States and Behaviors Task and I/O Behavior When Update IO While In Stop Is Not Selected When the Update IO while in stop setting is not selected, the controller sets the I/O to either the Keep current values or Set all outputs to default condition (as adjusted for output forcing if used). After this, the following becomes true: The Read Inputs operation ceases. The %I input memory variablea are frozen at their last values. The Task Processing operation is not executed. The Write Outputs operation ceases. The %Q output memory variables can be updated via the Serial, and USB connections. However, the physical outputs are unaffected and retain the state specified by the configuration options. 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. CAN Behavior When Update IO While In Stop Is Not Selected The following is true for the CAN buses when the Update IO while in stop setting is not selected: The CAN Master ceases communications. Devices on the CAN bus assume their configured fallback states. TPDO and RPDO exchanges cease. Optional SDO, if configured, exchanges cease. The Heartbeat and Node Guarding functions, if configured, stop. The current or default values, as appropriate, are written to the TPDOs and sent once before stopping the CAN Master. 52 EIO0000000384 04/2012
7.3 State Transitions and System Events Overview Controller States and Behaviors This section begins with an explanation of the output states possible for the controller. It then presents the system commands used to transition between controller states and the system events that can also affect these states. It concludes with an explanation of the Remanent variables, and the circumstances under which different variables and data types are retained through state transitions. What’s in this Section? This section contains the following topics: Topic Page Controller States and Output Behavior 54 Commanding State Transitions 57 Error Detection, Types, and Management 63 Remanent Variables 64 EIO0000000384 04/2012 53
