› Solutions › OT Change Management & Version Control

Every change.
Every author.
Every reason.

Octoplant provides version control and change management for OT: it tracks every change to every device configuration: what changed, who changed it, when, and why - detects modifications nobody documented, and lets engineers compare any two versions of a device program side by side.

The undocumented
change is the
expensive one.

Most production incidents trace back not to failures but to changes: a contractor's quick fix, a parameter tweaked at 2 a.m., a setpoint that drifted. Octoplant’s automated change detection compares the running state against the last approved version and alerts you to every difference - before the night shift finds it the hard way.

Accountability
for everyone who
touches a device.

In-house engineers, OEMs, external service providers: every modification is logged with author, timestamp, and documentation. Granular access management controls who may change what. When something looks wrong, the history shows exactly where to look.

Compare.
Decide.
Roll back.

Octoplant shows exactly what changed between versions or between a stored version and the device state - from logic and parameters to configuration details. Engineers can understand the difference before deciding whether to approve it, investigate it, or return to a known-good version.

One change process.
Across your OT environment.

Siemens, Rockwell, Schneider, ABB, Beckhoff, robots, HMIs, SCADA, drives, and legacy systems don’t have to mean separate change-management processes. Octoplant creates a consistent approach to versioning, comparison, approval, and traceability across heterogeneous automation environments – from one production line to multiple sites.

Change history that
becomes audit evidence.

Every version, approval, user action, and configuration change creates a traceable history as part of normal operations. That gives engineering teams the documentation they need for internal controls and gives compliance teams defensible evidence when audits and inspections arrive.

What gets captured, for every change.

	Question	Answered by
	What changed?	Octoplant's Smart Compare identifies the exact differences between versions and device states, helping engineers see changes in programs, parameters, configurations, and other device-specific data instead of manually comparing files.
	Who changed it?	Every checked-in version is linked to a user, creating clear accountability for internal engineers, contractors, OEMs, and other authorized users working on production systems.
	When did it change?	Every version and recorded modification is timestamped, creating a chronological history of how a device configuration evolved and helping teams correlate changes with production incidents.
	Why was it changed?	Version documentation captures the reason and context behind a modification, so future engineers don't have to reconstruct why a configuration differs from the previous state.
	Was the change authorized?	Role-based access and permissions define who can work with specific systems and configurations, helping prevent uncontrolled changes and separating responsibilities where required.
	Was it reviewed and approved?	Configurable approval workflows provide a controlled path from modification to approved version, with the approval becoming part of the traceable change history.
	Is production running the approved version?	Automated jobs compare the current device state with the stored reference version, exposing configuration drift and differences that may have occurred outside the controlled workflow.
	Did someone change the device outside Octoplant?	Device comparisons can reveal differences between the live configuration and the version stored in Octoplant, helping identify external or undocumented modifications.
	What was running before the change?	Previous versions remain centrally available in the version history, giving engineers a reliable reference for what was deployed before a modification was made.
	Can we undo it?	Known-good versions remain available for recovery, allowing teams to return to a previously validated configuration when a change causes problems or needs to be reversed.
	Can we prove what happened?	Versions, users, timestamps, comparisons, approvals, and change documentation create a traceable audit history that supports investigations, internal controls, and compliance evidence.
	Is this happening somewhere else?	Centralized change and version information provides a consistent view across devices and sites, helping teams identify recurring deviations and establish common change-management standards across the OT environment.

Take control
of change.

Every change matters. Octoplant automatically tracks, versions, and documents every modification across your OT environment, giving you complete visibility into who changed what, when, why, and how. Detect unauthorised changes, compare versions side by side, and restore approved configurations in minutes—so you can reduce risk, maintain control, and keep production running.
