Starting/Stopping Report Making

Report making can be started or stopped in two ways:

• DR command

• Use the event/action functions to define the start/stop of making a report for the following events:

Edge action: You can define every event as an edge action to start/stop report making.

Level action:You can use remote, alarm, relay signals as events to start/stop report making.

Report making starts at the same time that any of these events occur. Report

making stops when the event clears.

Note

• If you start report making, all reports created up to that point are reset.

• When report making is in progress, you cannot make changes to measurement channels, measuring ranges or dates and

times nor can you copy information on the ranges.

• If any computed data are included in your report making, let computing start first and then get report making started. If you

fail to enable computing, the data in your reports will become meaningless because no change takes place on the computed

data.

• If you want the start of computing and report making enabled at the same time, use the event/action functions to assign both

of these instructions to the same event as actions.

Time Relationship Between the report start/stop and report making

The following figure shows the time relationship between the report start/stop and report making.

Stop of report making

• Data items included in the first round of report making after the start of report making are

fewer in number than those included in the second and subsequent rounds of report making.

• If the time when data are sampled coincides with the time to stop report making, the DA

samples data before stopping report making. The report created when the DA stops making

reports thus includes those data.

• If the time when report making is started coincides with the time the report is created, the start

of report making precedes. Thus, no report is created.

• If the time when data are sampled coincides with the time to start report making, the data

sampled at the same time report making started are included in first round of report making.

The report created when the DA stops making reports thus includes those data.

• If you have defined timer and match-time signals as events using the event/action functions so

the time report making starts matches the time the report is created, data items included in the

first round of report making are one data item greater in number than those included in the

second or any subsequent round of report making.
