The test command within IEC60870-5 is used to test the whole loop from monitoring station to the application on the monitored station.
For the AC500 this implies to have an IEC1131 action on receiving a test command in the user application. So the test request must be received by the user application and must also be answered by the user application.
The interface for this is build from 3 Function Blocks:
- IEC60870_SEND_C_TS_NA_1_ACT to request a test and verify if the correct response was received.
2 Function Blocks on the tested end.
- IEC60870_REC_C_TS_NA_1 to receive an actual test request.
- IEC60870_SEND_C_TS_NA_1_ACTCON to answer an actual test request
For a successful test the testing station needs to request a test by sending a C_TS_NA_1 ACT request to the tested station.
The tested station needs to detect the test request and answer by sending a C_TS_NA_1 ACTCON confirmation with the data received.
The protocol implementation will make sure the correct time stamps are being send, but for the test sequence and address the tested station is responsible
