Control system having multiple control apparatuses

A control method comprising the steps of:

• executing, in a first control apparatus, an instruction of a control program stored in a memory of said first control apparatus, said instruction containing control data;
• transmitting said control data from said first control apparatus to a second control apparatus during execution of said control program;
• and
• causing said second control apparatus to control an object in accordance with the control data of the instruction of said control program, wherein said control data includes data for identifying a positioning target address to which said object is controlled to be moved, and speed data representing the speed at which said object is to be moved to said positioning target address.

A control system comprising:

• a first control apparatus including:
• a memory for driving a first motor in accordance with instructions of a control program stored in said memory, said instructions containing control data and being executed by said first control apparatus;
• and a communication control section for transmitting the control data of certain of said instructions during execution of said control program in said first control apparatus;
• a second control apparatus for driving a second motor;
• and
• a transmission path for conveying the control data from said first control apparatus to said second control apparatus,
• wherein said second control apparatus drives said second motor in accordance with the control data.

A control method comprising the steps of:

• executing, in a first control apparatus, a first instruction of a control program stored in a memory of said first control apparatus to cause said first control apparatus to drive a first motor;
• causing said first control apparatus to execute a second instruction of said control program, said second instruction containing control data;
• transmitting said control data from said first control apparatus to a second control apparatus during execution of said control program in said first control apparatus;
• and
• causing a second control apparatus to drive a second motor in accordance with the control data of the second instruction of said control program.
