The calculation model is based on actual customer feedback from the energy, water, and manufacturing sectors.
With secure VPN access to the OT network, technicians can diagnose malfunctions from their desks. Between 70 and 80 percent of on-site visits turn out to be unnecessary after remote diagnosis.
Of the diagnosed issues, half can be resolved remotely: PLC restart, parameter update, network reconfiguration, and firmware reset.
When a service call is unavoidable (due to a hardware failure or a part replacement), the technician arrives with the correct diagnosis and the right equipment—ensuring an efficient first visit.
