Tech-Link allows certified factory engineers and Cat dealer technicians to access Cat® switchgear through a password-protected connection and remotely make software changes ranging from simple sensor and dashboard edits to complex adjustments in the sequence of operation. Operating through a network or cellular interface, it is especially useful for switchgear applications in remote locations that would otherwise require a costly site visit from a technician. It is initially available for applications in North and South America as an optional hardware upgrade and service offering for all new Cat switchgear operating at 50 Hz and 60 Hz. Retrofit packages are available for select applications as determined on a case-by-case basis. It is certified to ISO/IEC 27001 requirements for information security management systems.
