Define the pumping sequence
A PLC pump control panel coordinates pumps, levels, pressure, valves, drives, alarms, and remote monitoring through a defined process sequence. The PLC is only one part of the system; the instruments, motor interfaces, and failure behavior determine the panel scope.
Inputs to collect
| Input | Why it matters |
|---|---|
| Pump and motor schedule | Defines starters, VFDs, protection, and feedback |
| Level, pressure, and flow points | Establishes automatic commands and alarms |
| Lead-lag and standby logic | Defines alternation and failed-pump response |
| PLC, HMI, and SCADA interfaces | Clarifies data ownership and remote operation |
| Environment and cable entry | Affects enclosure, cooling, drainage, and service |
Scope boundary
This article does not validate hydraulic capacity, PLC software, or commissioning results. Confirm the sequence and interfaces with the controls and process engineers.
