7. FAQ (Q & A)

Q1: What does the “+125840‑02” signify?
A1: It indicates an additional I/O and/or network interface module paired with the main chassis to extend functionality.

Q2: Which sensors are supported?
A2: Accepts proximity probes, vibration (velocity or acceleration), and displacement transducers, configuration‑flexible per channel.

Q3: Is Ethernet communication encrypted out of the box?
A3: Encryption isn’t built in. Secure connections must be achieved via external network tools like VPN gateways.

Q4: Can modules be swapped without shutting down the system?
A4: No. Power must be turned off before replacement to avoid interrupting measurements and prevent equipment damage.

Q5: Are analog outputs configurable?
A5: Yes, output spans (e.g., 4–20 mA ranges) and scaling are adjustable using a configuration interface.

Q6: Does it support firmware updates remotely?
A6: Yes—via RS‑485 or Ethernet if available. Updates require reboot, and a defined update protocol must be followed.

Q7: Is event history stored within the device?
A7: Minimal fault/event logging is available on board; long‑term data must be stored in external systems.

Q8: What routine maintenance is advised?
A8: Visual inspections of wiring, firmware updates, relay function checks, and calibration of analog outputs should be performed annually.

Q9: Can this fit into critical safety‑instrumented systems?
A9: Relay outputs can be looped into safety circuits, but the device itself isn’t certified as an SIS element.

Q10: How does it behave during power failure?
A10: On power loss, the device resets. Relay outputs transition to their preconfigured safe state, and analog outputs go into predetermined fixed values.
