Profinet / EtherNet/IP Deterministic Networks
The 1738-IB8M8 integrates into distributed ArmorPoint I/O networks while maintaining deterministic signal delivery over EtherNet/IP. It ensures I/O density scaling without impacting backplane communication timing. Module firmware is compatible with standard Rockwell Automation controller updates, supporting hot-swap insertion with minimal network disturbance.
Frequently Asked Questions
Q: Can the 1738-IB8M8 module be hot-swapped?
A: Yes, it supports field replacement while powered, provided downstream wiring is properly isolated and adherence to ArmorPoint insertion sequence is maintained.
Q: Are the input channels electrically isolated?
A: No, the 8 sinking inputs are non-isolated. Care should be taken to avoid ground loops.
Q: What connector type is used for field wiring?
A: The module uses M8 (Pico) connectors, suitable for shielded industrial cabling.
Field Installation Guidelines
-
Install the module in the designated ArmorPoint rack or expansion assembly following mechanical latching sequence.
-
Ensure all M8 connectors are fully seated and sealed to maintain IP67/IP69K protection.
-
Route field wiring separately from high-energy AC or switching circuits to minimize electrical noise.
-
Connect shields according to local grounding practices; single-point grounding is recommended.
-
Inspect connectors and cable seals periodically for damage, moisture ingress, or loose terminations.
-
De-energize power when modifying module placement or field connections.
