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.
JS1_J1939 Function Block Inputs
Input Type Range Description
SA U8 0-253 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.

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.
0x8008
1000 Msg value > 3 or < 1. 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.
SA value > 253 or < 0. Incorrect or no message may be
received. Data presented to the
application may be incorrect.
Verify correct SA for connected
hardware and set value within its
0–253 range.
*
Bit 16 set to 1 identifies a standard Danfoss status or fault code.
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 ±10000.
•
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.
