4. Ensure that the operator enters
downtime reason for any device before
it is restarted.
5. Capture minor stoppages of machines
and raise appropriate alerts in real-time.
6. Capture the results of testing by vision
system, reasons for rejection and raise
appropriate real-time alerts for
improvement.
7. Regulation of cooling system output
depending upon the amount of
equipment running. Note that cooling
systems may be supplying coolant to
The diagram in Figure 2 depicts the
workflow.
The following are some of the workflow
rules / behaviors that should be
incorporated / captured in an IIoT system:
1. Cyclic behavior of production devices.
See figure 3.
2. Sequence of operations on metal parts.
3. Timely alerts required to ensure
availability of parts and additional
components at each stage of assembly.
