Applied Systems Engineering ASE2000 User Manual

ASE2000 V2 Communication Test Set User Manual 204
28.9.3. IEC 60870-5-104 Task Mode Master Simulation
IEC 60870-5-104 does not have a Class Scan function since the Controlled Station sends point
data independently of requests from the Controlling Station. Whether the ASE2000 sends a
General Interrogation message periodically or only once is controlled by the Frequency property.
The default value, 2.000 seconds, causes a General Interrogation to be sent once every 2
seconds. A Frequency setting of -1 causes a General Interrogation to be sent only once when
the task is started, while keeping communication open until stopped by the user. This is di󰀨erent
from the Send Once option, which causes a General Interrogation to be sent once when the task
is started, but then stops communication when the General Interrogation completes.
