Abstract
A control apparatus for controlling a controlled object including controlled elements comprises a host processor, a plurality of slave modules and a communication network for providing communication between the host processor and the slave modules. The host processor interprets a control program to generate commands for the controlled elements in response to demands send from the slave modules. These commands are sent via the communication network to the respective slave modules. Each slave module is allotted to a controlled element and has a processor which interprets and executes the commands for its allotted controlled element and generates a demand upon finishing the execution of a command. This demand is sent via the communication network to the host processor and causes the next command to be generated.
