Abstract
A microcomputer is provided to generate PLC instructions. The microcomputer converts the PLC instructions into machine codes which are converted into execution instructions. The microcomputer is further provided with at least one hardware interface for controlling at least one controllable member. The hardware interface converts the execution instructions into control signals which are supplied to the controllable member. The controllable member connects on the hardware interface.
Claims9
A microcomputer comprising a bus structure on which at least a memory and a user interface are connected, said microcomputer having an operating system provided for processing at least one PC application, said microcomputer further comprising:
- (a) an instruction generator, incorporated in the operating system, provided for generating programmable logical controller's instructions for controlling a plurality of controllable members and for converting the programmable logical controller's instructions into machine codes under control of the operating system,
- (b) at least one hardware interface, connected to said bus structure, provided for co-operating with the instruction generator, and
- (c) a central processing unit, connected to said bus structure and provided for converting the machine codes into execution instructions and for supplying these execution instructions via said bus structure to the hardware interface, whereby said hardware interface is provided for
- converting said execution instructions into control signals for controlling said plurality of controllable members,
- selectively supplying said control signals to said plurality of controllable members which are connectable onto said hardware interface, and
- receiving data supplied by said controllable members and forwarding them to said instruction generator.
