Problems solved by technology

However, in order to input the same signal to both control devices, it is not easy to retrofit the equipment for parallel operation to the existing control system in operation, and there is concern about the influence on the work status of the workshop.
In addition, there is a constraint that the specifications of the signals input to the newly installed control equipment must be the same as those of the aging existing control equipment.

Embodiment approach 1

[0034] figure 1 It is a figure for explaining the structure of the control system which controls a steel production line (steel workshop). exist figure 1 The new control system 1, the established control system 2 and the computer update test auxiliary device 4 are depicted in .

[0035] The control object of the new control system 1 is the same as that of the existing control system 2, which is the steel production line. The computer update test support device 4 is capable of giving the actual operation data in the existing control system 2 to the new control system 1 in order to assist the function confirmation test required when updating the existing control system 2 to the new control system 1 test object device. The test target devices are a newly installed computer 11 and a newly installed gateway (newly installed GW) 12 .

[0036] (New control system)

[0037] The new control system 1 includes a new computer 11 , a new gateway 12 , a plurality of new programmable lo...

Embodiment approach 2

[0074] Next, refer to Figure 5 Embodiment 2 of the present invention will be described. In the first embodiment described above, as an example, the case where the data collected by the computer update test support device 4 is output to the newly installed lower-level network 15 in real time at the collection timing has been described. However, there are cases where it is desired to repeatedly simulate in the new control system 1 the same situation as the control performed in the past in the existing control system 2 regardless of the actual production implementation status in the existing control system 2 .

[0075] Figure 5 It is a block diagram for explaining the structure of the computer update test support apparatus 4 concerning Embodiment 2 of this invention. Figure 5 The configuration shown is the same as that in which the setting information 65 is added to the test support unit 6 and the processing of the test data output unit 64 is expanded. image 3 is the same....

Embodiment approach 3

[0081] Next, refer to Figure 6 Embodiment 3 of the present invention will be described. In the first embodiment described above, the function of displaying the collection timing and data content of packets has been described. However, if there is also a function to compare and display product quality data before and after the computer update, the function confirmation test will become more efficient.

[0082] Figure 6 It is a block diagram for explaining the configuration of the computer update test support device 4 according to Embodiment 3 of the present invention. Figure 6 The shown configuration is similar to that in which the shared memory collection unit 66, the quality data totaling unit 67, and the shared memory data storage unit 623 are added to the test support unit 6, and the processing of the data display unit 63 is expanded. Figure 5 is the same.

[0083] The shared memory collection unit 66 collects data stored in the shared memory 310 of the newly instal...

Abstract

A computer update test assistance device (4) is connected to both an existing higher-level network (24) and a newly installed lower-level network (15). A HUB (5) has a port mirroring function to capture packets flowing through the existing higher-level network (24) during the actual operation of a steel production line. A packet data accumulation unit (621) accumulates packet data comprising the collection times and data content of the packets captured by the HUB (5). A test data output unit (64) writes packet data content to storage regions of a common memory (310) that correspond to addresses of the common memory (310), in accordance with a test data definition table (622), while following the timing between the collection times of the packets captured by the HUB (5), said packet data content being required for a newly installed computer (11) to perform a calculation process.

Description

technical field [0001] The present invention relates to a computer update test auxiliary device, and particularly relates to a computer update test auxiliary device suitable for a function confirmation test when an existing control system of a steel production line is updated to a new control system. Background technique [0002] There is known a control system in which a high-level computer and a low-level programmable logic controller (PLC) are connected in a data-communicative manner, and cooperate to control the operation of each device constituting a steel production line. When updating an existing control system to a new control system due to aging of the control system, etc., it is necessary to perform a function confirmation test of the new control system. [0003] As one of the test methods, parallel run (parallel run) is known (Japanese Patent Laid-Open No. 2017-41000). According to parallel operation, the verification of an update can be performed by inputting th...
