Lock the first management control data ISTo of abnormality detection and specify and be stored in one in the data group of IDX address forms
Second management monitoring data IDXo.IDX address dates are formed with as shown in Figure 9 in the management data portion 22 of other main website 2
Form, each transmission formed with initial signal ST and subsequent control monitoring data area and management data area follow
Ring, according to the second management control data IXDo to fully entering the gradually good preceding leading address of assignment of allocation of substation 7.
The data of the IDX address forms carried out according to the second management control data IDXo be appointed as according to form numbering and
Carry out.I.e. the index address data (#ad0) of form numbering 1 are chosen and exported as the second management control data IDXo first.
And as each transmission circulates, gradually it is changed to substation grouped data and is changed into " 1 " each form numbering front number of addresses of correspondence
According to.But the order of the data of IDX address forms and unrestricted is specified with the second management control data IDXo, such as also can be according to
The priority come according to function.
Substation 6 is exported when the second management control data IDXo is consistent with substation Self address, is interlocked according to oneself abnormal
The output of testing agency, the management monitoring signal being made up of the abnormal or normal data of display and interlock is overlapped in management monitoring
Data area.Receive to capture to manage in this Self management monitoring signal of main website 2 and monitor that data deliver to control unit 1.
In control unit 1, according to the content of the second management monitoring parallel data 17, predetermined processing is carried out.Specifically
If two management monitoring parallel datas 17 show abnormal person, then abnormal represent is performed.When management monitoring data are " 0 " again, judge
For common data signal line DP, DN broken string, the display of such content is carried out.
Whether control unit 1 by above step, will appreciate that the output section 8 of corresponding output substation 6 is each has connection different
Situation normal or that interlocking is abnormal.
Other import and export designated value RD, condition substation can be done with reference to address RADR and data indicated value ID by control unit side
Appropriate change.Under this situation, by display change import and export designated value RD, condition substation with reference to address RADR or data indicated value
Import and export designated value RD, condition substation reference address RADR or data indicated value ID number after ID data and change
According to management control data region is overlapped in, it is a little to capture this in the input side of substation 7.
In this control monitoring signal transfer system, except the detection that interlocking is abnormal, and the data specified can be monitored.This shape
Under condition, gateway mechanism 62 shown in dotted lines in Figure 7 is arranged at, to the input of this gateway mechanism 62 as the data 63 of monitoring object
Meanwhile specify the output monitoring signal of testing agency 53 from substation address.And by will input monitor command data as first
Management control data ISTo is sent to corresponding output substation 6 from main website 2, and Monitoring Data 63 will in appointed output substation 6
Data output can be monitored as management by managing monitoring data transport mechanisms 45 from gateway mechanism 62, therefore allow the side of control unit 1
It can grasp.
