Batch reporting in SCADA systems follows a step-by-step flow from starting a batch, collecting and processing data, generating and reviewing the report, then sending or storing it.

Execution Sample

SCADA systems

start_batch()
collect_data()
process_data()
generate_report()
review_report()
send_report()
end_batch()

This code simulates the batch reporting process by calling functions in order to start, collect, process, generate, review, send, and end the batch.

Process Table

Step	Action	Input/Condition	Output/Result
1	start_batch()	Batch not started	Batch status: started
2	collect_data()	Batch started	Data collected: sensor readings
3	process_data()	Data collected	Data processed: aggregated values
4	generate_report()	Data processed	Report generated: summary document
5	review_report()	Report generated	Report reviewed: approved
6	send_report()	Report approved	Report sent/stored successfully
7	end_batch()	Report sent	Batch status: ended

💡 Batch ends after report is sent and batch status is set to ended

Status Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	After Step 4	After Step 5	After Step 6	Final
batch_status	not started	started	started	started	started	started	started	ended
data	none	none	sensor readings	aggregated values	aggregated values	aggregated values	aggregated values	aggregated values
report	none	none	none	summary document	approved	sent/stored	sent/stored	sent/stored

Key Moments - 2 Insights

Why does the batch_status remain 'started' during data collection and processing steps?

Because the batch is ongoing until the end_batch() function is called, as shown in execution_table rows 1 to 6 where batch_status stays 'started' until step 7.

What happens if the report is not approved during review?

The process would pause or loop back for corrections before sending, but in this trace, review_report() outputs 'approved' at step 5, allowing the flow to continue.

Visual Quiz - 3 Questions

Look at the execution_table, what is the batch_status after step 3?

A ended

B started

C not started

D paused

💡 Hint

Refer to variable_tracker row 'batch_status' after Step 3 column

At which step is the report generated?

A Step 4

B Step 6

C Step 2

D Step 7

💡 Hint

Check execution_table row where action is generate_report()

If the report was not approved at step 5, what would likely happen next?

A Batch ends immediately

B Report is sent anyway

C Process loops back for corrections

D Data collection restarts

💡 Hint

Consider the review_report() output and typical batch reporting flow

Concept Snapshot

Batch reporting steps:
1. Start batch
2. Collect data
3. Process data
4. Generate report
5. Review report
6. Send or store report
7. End batch
Batch status tracks progress; report approval is key before sending.

Full Transcript

Batch reporting in SCADA systems involves starting a batch, collecting sensor data, processing it, generating a summary report, reviewing and approving the report, sending or storing it, and finally ending the batch. The batch status variable tracks whether the batch is ongoing or ended. Data moves from raw sensor readings to processed aggregated values. The report must be approved before sending. This flow ensures organized and reliable batch reporting.
