Local Rules and Controlled Outputs for Plant Panels

Rules run on the gateway at the site and act on outputs there, such as a pump, a lamp and hooter or an interlock. Manual override stays at the panel, and every action is logged.

Where the rules run

Local rules sit on the gateway at the site and not in the cloud. A rule that stops a pump at a set level acts on the reading the gateway has just taken without waiting for a server to reply. The internet is not part of that path. Connectivity is chosen per site, and the rules run on the gateway whichever link is used.

What a local rule can do

Stop a pump at a set level

A tank or sump reading reaches the limit agreed with your team, and the gateway switches the pump off. The same rule can be set for a start level.

Lamp and hooter at the panel

The indication lamp and the hooter at the panel follow the same thresholds as the screen. They still work when the network is down.

Interlock

A condition on one machine can hold or release another. Which pairs are interlocked is decided with your maintenance team during the site visit.

Manual override at the panel

Whoever stands at the panel can take control back. The override sits with the operator and does not depend on the dashboard.

Every action in the log

The log records which rule acted, on which output and at what time. A manual override is recorded in the same place.

Fitting, wiring and permission

Outputs are wired by an electrician who works at your site, to points agreed in the written plan that follows the site visit and the walk through the panels. Reading from PLCs and drives is done without disturbing the control system. Any output that acts on a machine is agreed with you during scoping. Where a machine is under warranty or AMC, the supplier’s permission comes first.

FAQ

Frequently asked questions

Does it keep switching outputs when the internet is down?

Yes. The rules sit on the gateway, so the hooter, the lamp and an interlock still act without a network. Alerts on WhatsApp and SMS arrive after the link returns.

Can an operator stop a rule from acting?

Yes. Manual override stays at the panel. The action is recorded, so the shift review shows when control was taken back.

Is this a certified safety system?

No. It is a monitoring layer with local actions. Whether a separate safeguard is required on a machine is for your engineers and the machine supplier to decide.

Who agrees which outputs the gateway controls?

Your maintenance team and supervisors, with the supplier where a machine is under warranty or AMC. The list is written down before any output is wired.
