ControlNet Communication and I/O Density Scaling
The 1738-ACNR functions as a ControlNet communication interface between ArmorPoint I/O assemblies and higher-level control systems. Through PointBus integration, a single adapter can support up to 63 connected I/O modules while maintaining deterministic network communications at 5 Mbps. This architecture allows distributed I/O expansion without requiring additional network adapters for each field device cluster.

Field Installation Guidelines
-
Mount the adapter according to ArmorPoint mechanical installation requirements and ensure all sealing surfaces remain intact.
-
Use compatible M12 network and power connectors to maintain the specified enclosure protection level.
-
Verify incoming supply voltage remains within the 10-28.8 VDC operating range before energizing the adapter.
-
Separate communication cables from high-current motor and drive conductors to reduce conducted electrical noise.
-
Ensure protective grounding is completed according to the control cabinet or machine grounding scheme.
-
Inspect connector seals, locking mechanisms, and cable glands periodically where exposure to moisture, vibration, or contaminants is present.
-
Confirm PointBus loading and connected module count remain within the supported system limits.
