    • It is an object of the invention to provide a pump jack pump-off control method and a pump jack control apparatus in which, even when the speed of a pump jack is reduced due to generation of a pump-off condition, the pump jack is not caused to stop due to the motor overload abnormality or the coagulated crude oil and, even when the pump-off condition is generated, the reduction of the production capacity of the pump jack can be prevented as much as possible. On detecting the pump-off condition, while the pump jack is in operation with the speed thereof being reduced, or while the pump jack is in operation at the lowest speed, according to the overload warning signal of an ac electric motor, the pump jack is switched over to its intermittent operation. Also, the pump jack can be operated in such a manner that the stroke speed of the pump jack in the up stroke operation can be switched from a sinusoidal wave form over to a rectangular wave form, or, in the operation of the pump jack by an inverter, the pump jack can be operated such that it can carry out its up stroke operation with a limit imposed on torque.

    • The present invention is built on a time out control apparatus to control the time out when a packet is transferred between terminal units connected to different buses. In the time out control apparatus, delay measuring means measures the delay time required for a response packet to be received after a request packet is sent to a terminal unit (control unit) connected via a bus. Delay information list generating means generates a delay information list in which the delay times measured by the delay measuring means are related to the individual identification information on the respective terminal units. Information output means reads out the delay time from the delay information list in accordance with a request from the terminal unit and outputs the delay time to the terminal unit. This sets the delay time on the time out register of the terminal unit.
