More Information

Overview Manuals Watchdog DriveBus I/O Mapping Application
  • Combines application-watchdog logic with two digital inputs and two digital outputs
  • Connects through the CI858 optical I/O-ring architecture
  • Uses dedicated NWIO1DI and NWIO1DO control-application function blocks

NWIO-01 64168533 is ABB's NWIO option unit for DriveBus supervision and small-scale digital I/O exchange.

The hardware monitors controller-application operation and transfers field states through the configured optical ring, with a selectable watchdog relationship for the documented output.

Before installation, verify product ID, field-voltage execution, I/O mapping, optical-ring order, watchdog timing, switch position, and CI858 software configuration.

Availability, condition, price, and shipping time for NWIO-01 64168533 are confirmed during quotation.

  • Select the documented 0.2 s or 1 s watchdog behavior for the application
  • Verify whether the hardware switch associates the watchdog with DO2
  • Test the safe output response when controller communication is intentionally interrupted
  • Place the unit in the configured CI858 optical I/O ring
  • Preserve optical-ring order and dataset mapping during replacement
  • Confirm ring communication before enabling dependent drive functions
  • Use NWIO1DI to read the documented input signals
  • Use NWIO1DO to command and supervise the output signals
  • Match DI voltage execution and field wiring to the installed unit
  • Watchdog supervision of an AC 800M drive-control application
  • Digital field-input acquisition through a CI858 optical I/O ring
  • Digital output control for DriveBus-connected auxiliary or status circuits
Description
NWIO-01 64168533 is an ABB watchdog and digital I/O option unit for AC 800M DriveBus systems.

It monitors controller-application communication and exchanges two digital inputs and two digital outputs through the CI858 optical I/O ring and dedicated software function blocks.

Before installation, verify the complete type and product ID, digital-input voltage execution, I/O mapping, optical-ring order, watchdog setting, and CI858 library configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which identity must match when ordering ABB NWIO-01 64168533?
Match both the type designation NWIO-01 and ABB product ID 64168533; also verify the installed input-voltage execution from the nameplate and wiring.
What should be checked before replacing ABB NWIO-01 64168533 in a DriveBus ring?
Record its optical-ring position, CI858 hardware-tree entry, input/output mapping, watchdog setting, function-block connections, and field-voltage version before removal.
How does ABB NWIO-01 64168533 supervise the control application?
Its watchdog logic monitors the documented application communication path and can control the designated output according to the selected watchdog arrangement.
Why might ABB NWIO-01 64168533 inputs not update in the controller?
Check the optical I/O ring, CI858 configuration, NWIO1DI function block, mapped dataset, DI voltage version, field wiring, and selected input filter.
Can either output of ABB NWIO-01 64168533 be used without checking watchdog selection?
No. ABB documents a switch arrangement that can associate the watchdog with DO2, so the physical setting and application logic must be reviewed before repurposing an output.
What must be verified after installing ABB NWIO-01 64168533?
Confirm ring communication, both input states, commanded output states, watchdog response, task execution timing, and the controller application's safe behavior under a simulated communication loss.
Does ABB NWIO-01 64168533 require dedicated software objects?
Yes. ABB documents NWIO1DI and NWIO1DO function blocks for reading and writing the unit; verify the installed DriveBus library and project mapping.
