- the output is processed [S204] and transmitted to the measurement station 16 through the measurement module communication interface 7.
- Inputs from the measuring station 16 include: 'Temperature program.
- Processing [S205] converts the signals of the temperature sensor 1 and the physical quantity sensor 13 and the state of the measurement module 8 into a communicable form and outputs the form.
- FIG. 3 shows software executed on the measurement station central processing unit and the storage device 13, and is executed for each measurement module 8 to be connected. In other words, when there are multiple connected measurement modules 8, the measurement stage Independent software as shown in FIG. 3 is executed on the central processing unit and the storage device 13.

- the main process by processing the communication with the measurement module 8 by an independent process, an error in communication that requires real-time performance is prevented.
- the main process generates a scheduled processing process and then generates a data storage process [S303] o
- the data storage process refers to the input transaction, and if data is sent from the measurement module 8 [S320], retrieves the data from the input transaction and stores it in the storage location [ S 3 2 1]. Also, if there is an inquiry about the presence or absence of data from the monitor station 23 [S32 22], it is processed [S32 23], and if there is a data transmission request from the monitor station 23 [S32] 4], and process it [S325]. (Details of [S322] to [; S325] and!: S330] to!: S331 will be described later.)

- the user specifies which data is to be monitored. For this purpose, an instruction is given to the user interface of the monitor station 23.
- the processing of the user interface of monitor station 23 [S402] calls the data identification processing subroutine of FIG.
- the called specific processing subroutine prompts the user for a host name or a network address, and receives the input [S501] o Connected to the network medium 24 As shown in FIG. 7, 26, a unique network address and a host name are assigned to each station. By specifying this, it is determined which measurement station 16 is to monitor the data.
- Measuring station 16 has several measuring modules as shown in Figure 7. —Because module 8 is connected, determine which measurement module 8 will be monitored next. For this purpose, the data identification processing subroutine inquires of the measurement station 16 whether or not each measurement module 8 connected to the identified measurement stage 16 has data. In the measuring station communication interface 9, a channel number is set for each connection port. On the network, there is a mechanism called a port number, which identifies a connection port for each software, because one software is shared by many software. By combining the port number and the channel number, an inquiry is made to the data storage process corresponding to each measurement module 8.

- the data transmission process creates a copy of the data [S330]. By creating a duplicate of the data, it is possible to prevent the data from being stored in the data storage process from being disturbed, and the data transmission process does not need to be aware of maintaining the consistency of the stored data.
- the data transmission process sends the data to the monitor station 23 as shown in the data transmission path 29 for the specified data storage process in FIG. 7 [S33 1].
- the data reception processing subroutine receives the transmitted data and displays the data [S602].
- data is monitored at a remote place.
- the first is another embodiment of the data specifying means.
- FIG. 8 is an explanatory diagram of another embodiment in which a broadcast communication function is used for data specifying means.
- Some networks support the broadcast function. For example, in TCP / IP, if transmission is performed by specifying the network address 192.16.6.0.255, transmission is performed to all the devices connected to the network.
- the advantage of this method is that the channels of all measurement stations on the network where the data is stored 3 ⁇ 4 ⁇ : 's ⁇ _ without specifying the measurement station 16 in advance.
- the second is another embodiment of the data specifying means.
- FIG. 9 is an explanatory diagram of another embodiment in which software for storing the presence or absence of data is prepared.
- the advantage of this method is that the communication volume on the network medium 24 is small, and the channel numbers of all measurement stations on the network can be displayed in a short time.
- the third is another embodiment of the means for transmitting data without interrupting the data storage means.
- Fig. 10 is an improvement of [S330] to [S331] in Fig. 3, and is changed from creating data copies in [S330] to creating copies of the number of data. It has been updated [S1001]. Since the data storage program only adds data to the data, the data count up to this point must be duplicated. Therefore, the data must not be duplicated. ⁇ Send data to monitor station 23 [S1002]].
- the fourth embodiment is another embodiment using a measurement module stage in which the measurement module 8 and the measurement station 16 are combined.
- FIG. 11 shows a hardware configuration of a measurement module station 42 in which the measurement module 8 and the measurement station 16 are combined.
