Diagnostic & Status Indicators
- ACTIVE LED: Green – normal operation.
- ADAPTER FAULT LED: Red – adapter fault.
- I/O RACK FAULT LED: Red – rack fault.
- Enhanced diagnostics ease troubleshooting.
- Two switch assemblies for configuration.
Installation & Wiring
- Mount in the left-most slot of the 1771 I/O chassis.
- Use Belden 9463 (or equivalent) cable for RIO link.
- Install terminating resistors (82 Ω or 150 Ω) at both ends of the daisy-chain.
- Supports 4, 8, 12, 16, or 32-slot chassis.
- Field wiring arm (1771-WB) included.
Compatibility & Communication
- Works with PLC 5 processors via RIO scanner port.
- Serial communication; parallel read/write to I/O modules.
- Daisy-chain topology with terminating resistors.
- Backplane scanning up to 2500 ft at 230.4 kbps.
- Improved scan time by skipping last 4 slots (saves I/O image space).
Typical Applications
- Distributed I/O for PLC 5 control systems.
- Remote actuator and sensor integration.
- Factory automation and process control.
- Retrofit and upgrade of legacy PLC 5 systems.
