Selection and integration
Verify signal and electrical ratings, communication or I/O architecture, mechanical mounting, environmental limits and controller compatibility together. Product-family similarity or appearance alone is not sufficient for substitution.
Installation and commissioning
Isolation, wiring, shielding and grounding, addressing, scaling and parameterization must follow the current manufacturer documentation. During commissioning, verify supply, diagnostics, I/O behavior and the complete functional test.
Maintenance and replacement
Periodic inspection should cover connectors, mounting, cables, environmental exposure and functional verification. Safety-related products require the applicable validation and proof-test procedures.
