Abstract
Abstract A program control device controls a plurality of power units of a controlled object having operation member means in accordance with program information which is memorized in a memory device. The program information consists of step information and point information. The point information instructs the command positional values of the operation member means. The step information includes a control command to control functions of the program control device and a memory address command to instruct a memory address of the point information to be read out from the memory device. A control device generates operation control signals to control the power units in accordance with the point informations which have been read out from the instructed memory addresses.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
183 words
A program control device for controlling a plurality of power units of a controlled object having operation member means in accordance with program information comprising: memory means for memorizing said program information in predetermined memory addresses therein, said program information consisting of step information and point information; step counter means for instructing a memory address of the step information to said memory means, said step information including a memory address command to instruct a memory address of the point information and a control command to control functions of said program control device; point counter means for instructing a memory address of the point information to said memory means in accordance with said memory address command; control signal generating circuit means for generating control signals in accordance with said control command; gate means for selectively connecting said step counter means and said point counter means to said memory means in response to said control signals; and control means for controlling said power units in accordance with the point informations which have been read out from said memory addresses instructed by said point counter means.
Claim 2
Dependent Claim
183 words
A program control device for controlling a plurality of power units of a controlled object having operation member means in accordance with program information comprising: memory means for memorizing said program information in predetermined memory addresses therein, said program information consisting of step information and point information; step counter means for instructing a memory address of the step information to said memory means, said step information including a memory address command to instruct a memory address of the point information and a control command to control functions of said program control device; point counter means for instructing a memory address of the point information to said memory means in accordance with said memory address command; control signal generating circuit means for generating control signals in accordance with said control command; gate means for selectively connecting said step counter means and said point counter means to said memory means in response to said control signals; and control means for controlling said power units in accordance with the point informations which have been read out from said memory addresses instructed by said point counter means.
Claim 3
Dependent Claim
73 words
A program control device according to claim 1, further comprising: an instruction register for registering said step information read out from said memory means, the memory address command of said step information being applied to said point counter in response to said control signals; and an instruction decoder connected to said instruction register for decoding the control command of said step information to apply the same to said control signal generating circuit means.
Claim 4
Dependent Claim
31 words
A program control device according to claim 1, wherein said point information indicates a command positional value of said operation member means in each of the operational axes of the same.
Claim 5
Dependent Claim
68 words
A program control device according to claim 3, wherein said control means comprises: register means for registering said command positional values; detecting means for obtaining actual positional values by detecting the movement of said operation member means; and, comparator means for comparing said actual positional values with said command positional values to generate operational control signals, said power units being controlled in accordance with said operational control signals.
Claim 6
Dependent Claim
52 words
A program control device according to claim 1, wherein said gate means comprises: first gate means for connecting said step counter means with said memory means in response to said control signals; and second gate means for connecting said point counter means with said memory means in response to said control signals.
Claim 7
Dependent Claim
43 words
