CONTROLLER IN FARM WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To prevent output system external equipment from running away due to a communication error among a master controller 71 and slave controllers SX1 to SX4. SOLUTION: This controller is obtained by connecting output system external equipment such as a hydraulic cylinder or an actuator installed in a travel part, a working part, etc., in a farm working machine to slave controllers SX1 to SX4, connecting one master controller 71 to the respective slave controllers SX1 to SX4 with a communication bus 82 and connecting the controllers with other first signal lines 99a to 99d and outputting a reset signal through the first signal lines 99a to 99d to at least the corresponding slave controllers SX1 to SX4 in which a communication error is produced or all thereof when the master controller 71 judges that the communication error is produced. The slave controllers SX1 to SX4 receiving the reset signal send driving stop signals or power source shutoff signals to the output system external equipment to stop the driving.
