Abstract
Interactive data processing unit which is located at a distance from an FA control unit and capable of direct access to a memory in the FA control unit. When an access request to a memory (,) in a CNC (,) is issued by a device in an MMC (,), a remote access control means (,) outputs the access request to the CNC (,). Upon reception of the access request, an internal data input/output means (,) in the CNC (,) makes access to the requested address by performing a direct memory access (DMA) operation to the memory (,). It writes the data into the memory when the access request is a write-request. On the other hand, when the access request is a read-request, the internal data input/output means (,) outputs the data to the MMC (,). The remote access control means (,) in the MMC (,) receives the data and forwards it to the device which issued the access request. The MMC (,) thereby makes access directly to the memory (,) in the CNC (,).
