Actual intervals depend on the environment and duty, but these are typical starting points:
A short maintenance plan agreed at handover helps your team plan outages and avoids unexpected failures.
To speed things up, keep your project number, equipment serial numbers and the latest program backups to hand when you contact us. Clear photos of nameplates, alarm screens and the inside of the cabinet are often enough for our engineers to identify the cause quickly.
Electrical and control equipment often outlives the electronics inside it. When PLCs, HMIs or drives reach end of life, we help you plan the upgrade: checking what can be reused, migrating programs to current platforms, replacing drives with modern units, and adding energy monitoring or remote access. Work is planned in stages and tested in advance so production stops are short.
Many problems can be solved without travel. With a secure remote-access connection approved by your IT department, our engineers can look at alarm histories, check PLC logic and HMI settings, and guide your technicians step by step. Remote sessions are only opened with your permission, and all changes are agreed and recorded. For international customers this means faster answers and lower support costs.
Contact us by phone, email or WhatsApp with your project name, equipment serial number or drawing number, a description of the problem and photos or alarm screenshots. An engineer will respond and, where possible, help remotely first.
