Honeywell has announced a significant change to how technical support is delivered through its Global Technical Assistance Center (GTAC).
Beginning March 15, 2026, customers will no longer be able to purchase Honeywell technical support on an ad-hoc or pay-per-call basis. Instead, access to GTAC will only be available to organizations with an active Solution Enhancement Support Program (SESP) agreement.
For facilities operating Honeywell distributed control systems (DCS), this change could affect how troubleshooting, engineering support, and system maintenance are handled going forward.
The policy was outlined in Honeywell’s February 2026 System HINTS newsletter, which describes the revised support requirements and pricing structure.
What Is Honeywell GTAC Support?
Honeywell GTAC support refers to technical assistance provided by Honeywell’s Global Technical Assistance Center (GTAC) for industrial automation systems. GTAC engineers help customers troubleshoot, diagnose, and resolve issues involving Honeywell control systems such as Experion PKS, TDC 3000, ControlEdge platforms, Safety Manager systems, and related industrial software.
GTAC support is typically accessed through Honeywell’s Solution Enhancement Support Program (SESP) service agreements, which provide customers with vendor technical support, software updates, and engineering assistance.
What Is Honeywell GTAC?
The Global Technical Assistance Center (GTAC) is Honeywell’s centralized technical support organization for industrial automation systems.
GTAC engineers assist customers with troubleshooting, diagnostics, configuration issues, and system support for many Honeywell technologies, including:
- Experion PKS
- TDC 3000
- ControlEdge platforms
- Safety Manager systems
- Honeywell cybersecurity tools
- industrial software and monitoring platforms
Historically, customers could access GTAC support either through a service agreement or by purchasing incident-based support when issues occurred.
Under the new policy, the incident-based option has been removed.
Honeywell’s New GTAC Support Policy
Honeywell’s updated support policy introduces several key changes that impact how organizations access GTAC technical assistance.
Active Service Agreement Now Required
GTAC support will only be available to organizations that maintain an active SESP service agreement.
Customers without an active agreement will not be eligible for Honeywell technical support.
Ad-Hoc Support Has Been Eliminated
Honeywell’s policy explicitly states that:
Support cannot be purchased on an ad-hoc or “as needed” basis.
This represents a major change from the traditional support model many industrial facilities relied on for occasional troubleshooting.
Additional Cost for 24/7 Support Coverage
Organizations that require 24/7 GTAC support coverage must pay an additional fee equal to 10% of the SESP agreement value.
This coverage applies only to specific emergency scenarios involving:
- Loss of View (LOV)
- Loss of Control (LOC)
Other types of technical support may still be handled during normal business hours.
Why This Policy Change Matters for Honeywell Control System Operators
Honeywell control systems are widely used across industrial sectors such as:
- oil and gas
- chemical manufacturing
- pharmaceuticals
- food and beverage production
- power generation
- specialty manufacturing
When a DCS issue occurs, engineers often need rapid assistance to diagnose problems such as:
- controller communication failures
- operator station issues
- alarm management problems
- system configuration errors
- network or server faults
- software upgrades or migrations
In the past, facilities that experienced occasional issues could contact Honeywell support only when needed.
With the removal of pay-per-incident support, organizations must now decide whether maintaining a full service contract makes sense for their operations.
Understanding the Cost Impact of SESP Contracts
The cost of a Solution Enhancement Support Program (SESP) agreement varies depending on system size, licensing, and configuration.
For larger installations, SESP contracts can represent a significant annual expense.
Facilities that require 24/7 support coverage may also need to include the additional 10% support surcharge required for around-the-clock assistance.
For organizations that only require occasional engineering support, maintaining a full vendor service agreement may not always be the most cost-effective option.
Alternative Support Options for Honeywell DCS Systems
Many organizations supplement or replace vendor service agreements with independent engineering support providers who specialize in industrial automation systems.
Independent automation engineers can often provide:
- troubleshooting assistance
- system diagnostics
- configuration support
- upgrade and migration planning
- engineering services for legacy systems
Industrial Design Solutions (IDS) provides engineering support for multiple Honeywell automation platforms.
Honeywell DCS Support
IDS engineers support a wide range of Honeywell distributed control systems, including both modern and legacy platforms.
Honeywell Experion Support
Experion PKS remains one of Honeywell’s most widely deployed DCS environments.
IDS provides troubleshooting, configuration assistance, engineering services, and system support for Experion installations.
Honeywell TDC 3000 Support
Many industrial facilities still operate legacy TDC 3000 systems that require specialized expertise for maintenance and troubleshooting.
IDS provides engineering support to help organizations maintain and operate these environments safely and effectively.
Preparing for the March 2026 GTAC Policy Change
Organizations operating Honeywell control systems may want to review their support strategy before the policy takes effect.
Key considerations may include:
- whether current systems are covered under an active SESP agreement
- expected technical support needs over the next several years
- costs associated with vendor service contracts
- long-term plans for system upgrades or modernization
Understanding these factors can help facilities ensure that they maintain access to the engineering expertise needed to keep critical control systems operating reliably.
For many automation engineers, vendor technical support has long been a safety net when troubleshooting complex DCS issues. The removal of pay-per-call access to Honeywell GTAC support may force many facilities to rethink how they obtain engineering assistance—especially for plants that only require occasional vendor expertise.
As Honeywell’s support model evolves, many organizations are beginning to explore independent engineering support as a way to maintain flexibility while still having access to experienced control system specialists.

Frequently Asked Questions About Honeywell GTAC Support
What is Honeywell GTAC?
GTAC (Global Technical Assistance Center) is Honeywell’s centralized technical support organization for its industrial automation platforms. GTAC engineers provide troubleshooting, diagnostics, and technical assistance for Honeywell control systems such as Experion PKS, TDC 3000, ControlEdge platforms, and related software solutions.

What does Loss of View or Loss of Control mean?
In Honeywell control systems, Loss of View (LOV) refers to situations where operators lose visibility into the control system interface or process data.
Loss of Control (LOC) refers to conditions where operators are unable to control or manipulate process variables through the system.
Under Honeywell’s updated policy, 24/7 GTAC support coverage is primarily limited to these types of critical events.
