Product overview
Network diagnostics
Lifecycle family of controller-independent network-access appliances for supported industrial Ethernet and fieldbus diagnostics.
Installed-base diagnosticsRetain documented access to the supported network while planning migration.
Variant boundaryPROFINET, Industrial Ethernet, PROFIBUS and other TH LINK products are not interchangeable.
Published lifecycleSofting publishes discontinuation/support dates for specified TH LINK variants; check the exact order number.
MigrationMap the installed variant to the Softing-listed smartLink or other successor.
Lifecycle / positioning: Specific TH LINK variants have published successor routes. TH LINK PROFINET → smartLink HW-PN; older TH LINK PROFIBUS → smartLink HW-DP.
Connection architecture
