PROBLEM TO BE SOLVED: To reduce the time required for testing a plant monitoring control system.SOLUTION: A testing device 11 transmits a test execution instruction to an auxiliary testing device 12 and a terminal 13. The terminal 13 extracts test procedure data D12 and test data D22 that correspond to the test execution instruction, out of test procedure data D1 and test data D2 which are stored in a terminal storage device 13a; on the basis of both pieces of the extracted data, simulatively operates a programmable controller 4; and transmits output data D5, which is to be output to a field device 5, to a monitoring control device 2. On the other hand, the auxiliary testing device 12 which has received the test execution instruction extracts test procedure data D11 and test data D21 that correspond to the test execution instruction and are related to itself, out of the test procedure data D1 and test data D2; and on the basis of both pieces of the extracted data and output data which is transmitted from the programmable controller 4, simulatively performs a monitoring or control operation.SELECTED DRAWING: Figure 1 |
