Abstract

PURPOSE:To achieve functional check of data processor even if no opposing data processor is connected, by providing a means which simulates the opposing data processor which intercommunicates with the data processor to own device. CONSTITUTION:In a data processing section 55, communication data of communication data format of lockout devices is formed and stored in a transmission register 54. A request code of communication between devices is stored in a register 56 and a request is made to a system interface device. The response data from the system interface device to this request is received at the data processing section 55 via a reception register 53 to discriminate if the locking is successful, and if locking is succeeded, the specified address of a scratch pad memory in the processing section is cleared. If not successful, interpretation is made at the section 55, and if this communication command is a condition code, the request code of lock release is stored to a register 56 and the data transfer device lock designation data is stored in the register 54.
