Challenge
Operators had local HMI visibility, but supervisors could not compare press behavior across lines. Changeover issues were discovered too late.
Modibus approach
Modibus read approved PLC tags, exposed cycle and fault states, and sent a compact event stream to the plant dashboard.
Outcome
Supervisors identified repeat changeover gaps and caught transfer misalignment earlier. The team kept PLC logic untouched, which helped controls engineers approve the project.
“Not touching the PLC code was the reason this moved quickly.”
