4 The JS1_J1939 function block configures the output of a JS1 Joystick with CAN. This joystick has a CAN (Controller Area Network) 2.0B output that uses the J1939 communication protocol. The JS1 Joystick with CAN is a highly configurable joystick that has: A joystick base with a single three-point Y-axis or with three-point X- and Y-axes. Up to three grip-mounted proportional three-point rocker switches. Up to 12 grip-mounted push-button switches. Function Block Inputs Inputs to the function block are described. Inputs Input Type Range Description SA U Specifies the factory-set source address of the joystick. All source addresses on the same CAN bus must be different. Do not use the same address twice. The Type code on the joystick label identifies the source address. Typical addresses are C33 (right), C34 (left), C35 (center), and C36 (auxiliary). Enter the source address in hexadecimal format as shown in the following examples: C33 (right) = 0x33 C34 (left) = 0x34 C35 (center) = 0x35 C36 (auxiliary) = 0x36 CAN Inputs CAN messages from the joystick. Route this bus to the CAN pin on this function block. CAN messages sent from the joystick to the function block contain information about the availability of joystick inputs, joystick input faults, and joystick commands. Function Block Outputs The outputs of the function block are described. Outputs Output Type Range Description Status Outputs a bus that contains the following status signals. Btn1_NA Btn12_NA BOOL Indicates if an input is available from a grip-mounted push-button switch. 4 Danfoss March 2018 AQ en-US0102

6 Outputs (continued) Output Type Range Description TimeOut_BJM BOOL Indicates if the function block receives a BJM (Basic Joystick Message) within a 100 ms timeout limit. This message reports joystick X-axis and Y-axis positions as well as the state of gripmounted button switches. When a message has not been seen for 100 ms, this signal becomes True. The function block then sets all Out signals associated with the message to either 0 or F. It sets all fault signals associated with the message to True. Once a message is seen again, this signal becomes False and the function block enables all Out signals associated with the message. It resets all fault signals associated with the message to False. T = Timeout fault. Message not received within 100 ms limit. F = Message received within 100 ms limit. TimeOut_EJM BOOL Indicates if the function block receives an EJM (Extended Joystick Message) within a 100 ms timeout limit. This message reports the position of grip-mounted proportional switches. When a message has not been seen for 100 ms, this signal becomes True. The function block then sets all Out signals associated with the message to either 0 or F. It sets all fault signals associated with the message to True. Once a message is seen again, this signal becomes False and the function block enables all Out signals associated with the message. It resets all fault signals associated with the message to False. T = Timeout fault. Message not received within 100 ms limit. F = Message received within 100 ms limit. NoMsgReceived_BJM BOOL No BJM received from the device. T = No message received since power on. F = At least one message has been received. NoMsgReceived_EJM BOOL No EJM received from the device. T = No message received since power on. F = At least one message has been received. XGrp_Det_Flt BOOL Indicates if the input from a grip-mounted, X-axis detent switch has a fault. XGrp_Flt BOOL Indicates if the input from a grip-mounted, X-axis proportional switch has a fault. X_Det_Flt BOOL Indicates if the input from a detent switch on the joystick s X-axis has a fault. X_Flt BOOL Indicates if the input from the joystick s X-axis has a fault. YGrp_Det_Flt BOOL Indicates if the input from a detent switch on the joystick s Y-axis has a fault. YGrp_Flt BOOL Indicates if the input from a grip-mounted, Y-axis proportional switch has a fault. Y_Det_Flt BOOL Indicates if the input from a detent switch on the joystick s Y-axis has a fault. Y_Flt BOOL Indicates if the input from the joystick s Y-axis has a fault. 6 Danfoss March 2018 AQ en-US0102

7 Outputs (continued) Output Type Range Description Out Outputs a bus that contains the following command signals. These signals indicate the position of each joystick axis and the state of push-button and detent switches. Btn1 Btn12 BOOL Indicates the states of grip-mounted push-button switches. T = Closed. F = Open. Rx_BJM BOOL Indicates when the function block receives a BJM (Basic Joystick Message). This message reports joystick X-axis and Y-axis positions as well as the state of gripmounted button switches. T = Message received. F = Message not received. Rx_EJM BOOL Indicates when the function block receives an EJM (Extended Joystick Message). This message reports the position of grip-mounted proportional switches. T = Message received. F = Message not received. Status U16 Reports the status of the function block. See Status Logic for more about this output. T_Axis_Det BOOL Indicates the state of a detent switch on the joystick s rotational (theta) axis. T = Closed. F = Open. T_Axis_Psn S to Indicates the position of the joystick s rotational (theta) axis = -100% = +100% XGrp_Det BOOL Indicates the state of a detent switch on a grip-mounted, X-axis proportional switch.

8 Status and Fault Logic Use status and fault codes to determine if the function block is operating properly. Status Logic This topic describes codes that can help you determine if the function block is operating properly. Status Hex * Binary Cause Response Correction Parameters are corrupt. 0x Msg value > 3 or < 1. Incorrect or no message may be received. Data presented to the application may be incorrect. SA value > 253 or < 0. * Bit 16 set to 1 identifies a standard Danfoss status or fault code. Incorrect or no message may be received. Data presented to the application may be incorrect. Verify correct Msg value for connected hardware and set value within its 1 3 range. Verify correct SA for connected hardware and set value within its range. Boolean Output Signals The changing states of the Status and Fault signals affect the value of Boolean output signals. Output Signal Status Signal State Fault Signal State Output Signal Value Btn1 Btn12, Rx_BJM, Rx_EJM, T_Axis_Det, XGrp_Det, X_Axis_Det, YGrp_Det, Y_Axis_Det F F T or F T T F T F F F T F For example: As long as the Status signal and the Fault signal for the Btn1 input are both F, the Btn1 output signal can be either T or F. As soon as either the Status signal or the Fault signal for the Btn1 input becomes T, the Btn1 output signal goes to and stays F. When the Status signal and the Fault signal for the Btn1 input are again both F, the Btn1 output signal returns to its normal T or F operation. Proportional Output Signals The states of the Status and Fault signals can change and affect the value of proportional output signals. Output Signal Status Signal State Fault Signal State Output Signal Value T_Axis_Psn, XGrp_Psn, X_Axis_Psn, YGrp_Psn, Y_Axis_Psn F F ±10000 T T 0 T F 0 F T 0 For example: As long as the Status signal and the Fault signal for the T_Axis_Psn input are both F, the T_Axis_Psn output signal ranges ± As soon as either the Status signal or the Fault signal for the T_Axis_Psn input becomes T, the T_Axis_Psn output signal goes to and stays at 0. When the Status signal and the Fault signal for the T_Axis_Psn input are again both F, the T_Axis_Psn output signal returns to its normal ±10000 operation. 8 Danfoss March 2018 AQ en-US0102

9 Function Block Connections Connections you can make with the function block are described. Item Description 1 Determines the CAN port connected to the joystick. 2 Configures the function block to listen for CAN data from the joystick s network address. 3 Output bus containing the joystick axis position, proportional grip inputs, and button states. 4 Reports faults for individual signals or communication timeout. 5 Reports Not Available state for each signal if connected joystick hardware does not support the function or for all signals if communication has not yet been established. Configuration of Input and Output Buses You do not have to change the configuration of either input or output buses to use the function block. Danfoss March 2018 AQ en-US0102 9
