The controller 1-1 (type 1) PV is stored in the communication buffer 12. The communication address at this time is 00003 as shown in FIG. 6, and the stored data at this time is data from 0 to 10000. Thereafter, the instrumentation data display / setting unit 17 requests the data conversion unit 13 to perform data conversion. The conversion equation at this time is RD / 100 as shown in FIG. Therefore, as a result, the data from the communication buffer 12 is converted into data from 0.0 to 100.0 and displayed on the CRT 18 in the display color (05).

Further, when the PV of the tag x in FIG. 6 is displayed on the CRT 18, the procedure is as follows.

As a result, data from 0 to 10000 is stored in the communication buffer 12. Thereafter, the instrumentation data display / setting means 17 issues a request to the communication means 11, and the SV of the tag 1
1 Sent to (Type 1). The communication address at this time is 00005 as shown in FIG.

The procedure for transmitting the SV of the tag x set in FIG. 6 to the controller 1-n (type n) is as follows. The instrumentation data display / setting means 17 inputs the data (data from 0.0 to 100.0) in the common instrumentation data structure 16 set from the keyboard 19, and then performs the data conversion to the data conversion means 13. Request. The conversion formula at this time is WD, that is, no conversion, as shown in FIG. As a result, the data of 0.0 to 100.0 is stored in the communication buffer 12. After that, display instrumentation data
The setting unit 17 issues a request to the communication unit 11, and the SV of the tag x is transmitted to the controller 1-n (type n). The communication address at this time is 90002 as shown in FIG.

As described above, the instrumentation data display / setting means 17 always sets SV to 0 regardless of the instrumentation data structure of the controllers 1-1, 1-2,..., 1-n of different types. It can be processed with values from 0.0 to 100.0.
