摘要： PURPOSE:To hold the communication function of a data processor for the trouble of a station ST by selecting one of outputs of STs other than the faulty ST and transferring the selected output to the data processor and a common transmission line as the output of a multiplexed ST device. CONSTITUTION:Ring data received from an input line 20 from a ring is transmitted to all ST input lines 30-1-30-3 by a data distributing mechanism 10-1 to be transmitted to all STs. Data received from an input line 40 from the data processor is transmitted to ST input lines 50-1-50-3 by a data distributing mechanism 10-2 similarly. Each ST transmits output data to the ring to output lines 31-1-31-3 and transmits output data to the data processor to output lines 51-1-51-3. A current ST selecting mechanism 5 selects one current ST and controls connection switches 11-1 and 11-2 through signal lines 12-1 and 12-2 to connect output lines from a current ST 4-3 to an output line 11 to the ring and an output line 41 to the data processor. The current ST selecting mechanism 5 monitors the state of each ST through signal lines 60-1-60-3.

摘要： PURPOSE:To grasp easily the existing location of a faulty station in a network at fault by generating identification information representing the physical connecting location of a general station by the station in connecting the station to the network and sending the message including the information to a management station. CONSTITUTION:The management station 3 of the network consists of a fault report communication frame 4 and a location represented by a local identifier. When a station (1-K) detects a fault, a console key of the station is used and generation of a fault is informed to the management station 3 by using a fault report frame 4. The frame 4 is a network management frame where FC 11 is set as '10000000', information of the location 5-P is stored by using a local identifier to an LA 20 and fault information is stored in an MI 21. The management station 3 uses the LA 20 that a fault exists in the station (1-K) in the location 5-P and then, for example, the maintenance personnel visits the location 5-P for the maintenance of the station (1-K). Thus, the maintenance efficiency is improved.

摘要： PURPOSE: To specify a fault location of star-ring type network without necessitating mounting a specific device, when an abnormalcy detection station (ST) shows a change by a pseudo-fault which is brought about intentionally, by judging that there is an actual fault near an upper stream of the ST.
CONSTITUTION: In the case where a fault P occurred between a transmission end of ST1-B and port 7-B, a control ST, first of all, releases the uppermost port 7-A through a signal wire 8-A after receiving a beacon and finding out an abnormalcy at a ring. Now that no state change is occurred, the control ST releases the next down stream port 7-B. Still the state does not change, then the control ST2 releases a further downstream port 7-C and connects the port 7-A and port 7-B normally after bypassing the port 7-C. Because no ring's abnormalcy is restored, the control ST connects the bypass of the port 7-C normally and the next upper port 7-B of port 7-C is bypassed. Thus the ring's abnormalcy is restored and the preceding procedure makes it possible to specify the abnormal port.

摘要： PURPOSE: To detect a duplicated fault of new station numbers by comparing a station number of a new station assembled newly in a large scale circuit network with a station number registered in a station number management table.
CONSTITUTION: A station ST5 connected newly to a bus ring 1 reports the own ring number and the own ST number to a management ST4. The management ST4 compares and collates the number with an ST number 12 registered already to a ring table 10 of all rings in the circuit network every time the newly assembled ST number is reported from the ST5 connected newly to the ring to check the rationality of the ST number of the ST5. Thus, the duplicated fault of the ST number is prevented.

摘要： PURPOSE:To reduce competition of memory access by providing two single port memories, a selector circuit that selects a address bus and data bus for each memory, and a write access competition avoidance controlling circuit. CONSTITUTION:When both memory accesses from a CPU1 and a CPU5 are read accesses, a bus 2 and a bus 6, a bus 4 and a bus 7 are connected to make simultaneous access possible. When accesses from the CPU1 and 5 are both write accesses, priority is given to earlier write access, and other access is prohibited. When writing, memory units 8 and 9 are written simultaneously by the CPU1 or 5. Thus, a dual port memory that enables simultaneous read access using existing IC memory can be constituted.

摘要： PURPOSE:To prevent the increment of load of a control station by collecting orderly the information for various network concentrated controls which are generated asynchronously with each other at each ordinary station. CONSTITUTION:When an ordinary station 3 has a request for a measure to be taken at a centralized control station 2, a measure request mechanism 11 recognizes the measure request for a control information memory mechanism 10. A control information collection control mechanism 12 has communication with a control information collection reply mechanism 13 of each station within a network and collects the control information. The mechanism 13 stores the contents of the mechanism 10 to a control information collection response 32 and gives a reply to the mechanism 12. The mechanism 12 actuates a measure control mechanism 21 in response to the control information collected from each station. While a measure reply mechanism 22 checks the presence or absence of the corresponding measure request of the mechanism 10 and then carries out the measure when said request mechanism 10 and then carries out the measure when said request exists. Then the mechanism 22 ignores the corresponding measure of the mechanism 10 and sends a reply of the end of the measure back to a measure control mechanism 21.

摘要： PURPOSE:To switch the display directions of a screen with no restarting by providing both horizontal and vertical display video memories as the storages which store the data to reflect the display on a display device. CONSTITUTION:A display controller 107 controls a liquid crystal display 108 and selects vertical display video memory 109 or a horizontal display video memory 110. The display 108 receives the information inputted from an input device 106 and the processed results, etc., via a display controller 107 and displays them. The memory 109 reflects the memory state on the display 108 when the vertical display is selected by a portable electronic equipment. Meanwhile the memory 110 reflects the memory state on the display 108 when the horizontal display is selected by the electronic equipment.
