Trace Selection
Program ⇒ Utilities ⇒ Trace
In conjunction with parameter F741 – F745, this parameter is used to monitor and store 4 ASD output waveform data points. The data may be read and stored as a function of a trip (At Trip) or it may be initiated by the activation of a discrete terminal activation (At Trigger). Set a discrete input terminal to Trace Back Trigger Signal and activate the terminal to initiate the At Trigger read/ store function.
Table 9 on pg. 242 lists the items that may be selected for the data read/store function along with the associated communication number for each selection.
The duration of the read/store cycle for the selected items is set at parameter F741.
To acquire and store the data a communications device and a PC are required. The H9 ASD supports the following communications protocols: RS485
