摘要:
A processing unit is connected to another processing unit through a system bus composed of serial signal communication line and synchronization signal communication line to be able to communicate therewith. When an operation unit detects abnormal state in the processing unit, the operation unit supplies notification of detection of the abnormal state to synchronization unit. The synchronization unit transmits the received detection notification of abnormal state to the other processing unit through the synchronization signal communication line. Conversion unit receives parallel communication data from the operation unit through important signal line instead of general signal line and converts the received parallel signal into serial signal to be transmitted to the other processing unit through the serial signal communication line, thereby soundness among processing units connected to the system bus is ensured when the system bus is configured to attain serial communication.

Without being restrained to a specific bus scheme, kinds of I/O modules connected to a processing module can be discriminated. Module exclusive selection parts respectively provided in I/O modules connected in a stacked form to a processing module via connectors judge only a module select signal input from terminals in the same position on processing module side connectors to be active. Based thereon, identification information of its own I/O module is output to a predetermined terminal on the connector. Without being restrained to a specific bus scheme, therefore, the processing module can acquire identification information of the I/O modules from a predetermined terminal on a connector. One I/O module can be selected by a simple module selection circuit scheme of inputting module select signals successively output from the processing module to terminals in the same position on processing module side connectors according to the connection order of the I/O modules.

In a process for producing an aromatic carboxylic acid, it is a dehydrating process which can achieve compactification of a step for removing water from a mixture of acetic acid and water produced in the production process, and which can reduce the consumed energy. In a production process of an aromatic carboxylic acid having an oxidation reaction step for producing a slurry of an aromatic carboxylic acid by carrying out liquid-phase oxidation reaction of an alkyl aromatic compound with an oxygen-containing gas in a solvent containing acetic acid in the presence of an oxidation catalyst, at least a portion of a mixture containing acetic acid and water produced in the production steps is separated into a permeable gas mainly comprising water and nonpermeable substances mainly comprising acetic acid, using a separation membrane having water selectivity.

When an RFID is attached to an object to assist testing operations, the following problems are encountered; (1) the RFID of write type tends to cause a failure and is troublesome due to the necessity of rewrite each time the situation is changed, (2) the incorporation of the reader function in a terminal block increases the cost, and (3) the known techniques are targeted for only the connecting operation and are not adapted for a sequence test that takes the most expense in time and effort. The operations are aided by using an RFID reader and a terminal having the function for accessing a database of circuit information, RFID information, and test procedure information.

The invention contemplates to improve versatility or flexibility of a system for managing a controller. In a data format converter, a computer constitutes reception unit for acquiring input information containing a program, etc, of a first data format and outputted from a programmer unit, direction extract unit for extracting a convert direction of a data format contained in the input information so acquired, data conversion rule acquisition unit for acquiring a conversion rule of a data format corresponding to the convert direction so extracted and convert execution means for converting the program, etc, of the first data format to a second data format. The program, etc, of the second data format converted is outputted to the controller. The program, etc, can be created in this way in an arbitrary data format different from the data format of the controller.

A computer system, being a stack bus system in which a plurality of computer modules are stacked and connected to one another and being capable of automatically matching and allocating bus resources such as clocks and interrupts, is provided. In the computer system including one system module and n peripheral modules, each peripheral module includes an interrupt selector, a clock selector, an arbitration signal selector, a resource decision unit, and a position identification unit. The position identification unit cooperates with a position configuration unit present in the system module to identify a position of the module, which includes the position identification unit, in the computer system, and autonomously decides bus resources used by the module. By allowing the interrupt selector, the clock selector, and the arbitration signal selector to select and use the decided bus resources, each peripheral module can match and configure the bus resources in the computer system.

摘要:
When executing sequential processing such as a ladder logic, converting a program formed of an instruction set of another processor to a program executable by an own processor in software and then conducting processing lowers the real time property. In a control system, a storage unit stores a program for the own processor and a program for another processor. A processor reads data from the storage unit, executes processing described as a program, and gives an instruction to change over a method for acquiring data from the storage unit, to a conversion instruction unit according to data contents. A changeover unit is connected to the storage unit directly or via the conversion unit to change over the data acquiring method according to an instruction from the conversion instruction unit. The conversion unit converts data read from the storage unit to data executable by the processor, according to a conversion scheme.
