Controls support agreements
Keep controls knowledge, program revisions and follow-up work organized. Agree scheduled support hours, backup reviews and an on-call arrangement that fits your site.
Signs you need this
- Program backups and revision records are difficult to locate.
- Small changes and recurring faults need planned follow-up.
- Your maintenance team needs a named controls contact and a defined escalation path.
What we do on a visit
- Back up the current PLC and HMI programs before any edit; confirm access and the working revision.
- Trace the fault through sequence logic, I/O, permissives, interlocks and drive diagnostics.
- Agree the change with your site team, make the scoped correction and test the affected operation.
- Document the changes, test results and outstanding actions; hand over the updated backup.

How a call-out works
- Share the platform, symptoms, location and urgency; we confirm the initial scope and availability.
- Agree site access, the shutdown window and who can authorize changes before the visit.
- Review the findings and test results together, then receive the change record and next actions.
