ABB DI840 3BSE020836R1 Drive Extender Bus Module

Description

Tests Hnet communication when an RFO Fiber Optic Repeater is

between a master and a controller acting as an I/O device. Checks

the ability to both transmit and receive Hnet messages. Requires

two controllers (redundant or primary) and the appropriate PBA,

Hnet cabling, and termination hardware. Set one controller to test

16 (master); the other to test 21. Both controllers provide pass/fail

indication.

NOTE: A Harmony block I/O set at test 21 can also serve as the

I/O device. This is the recommended setup for testing Hnet.

Unused 18-1F —

Group test 2 20 Executes tests 01 through 1F.

IISAC01 station and

redundancy link

redundant

22 Displays running count of bytes received by redundant controller

when primary controller is executing test 20. Provides the common

functionality of both tests 23 and 24.

I/O expander bus

fault time halt 2

25 Arms the fault timer and allows the I/O expander bus clock to stall.

This checks the controller ability to disengage from the I/O

expander bus in the event it can no longer drive the expander bus

clock. This test passes if controller halts with a 0x55 pattern dis

played on the LEDs. Fails if controller continues to operate with

any other pattern displayed on the LEDs.

NVRAM retention –

data storage 2

26 Stores a known data pattern in NVRAM for testing by the NVRAM

retention – data check test 27. Halts with LED pattern 0x55 if test

has completed writing data.

NOTE: Remove power from controller prior to running the NVRAM

retention – data check test. If practical leave controller unpowered

for one hour prior to running the data check test.

NVRAM retention –

data check

27 Verifies NVRAM holds data pattern stored in test 26. Provides nor

mal pass/fail indication.

Redundancy link

break

28 Tests redundancy links ability to generate and detect a break in the

transmission. An intentionally generated break is sent. The

receiver detects the break and in response sends a break back.

Requires two controllers (redundant) and the appropriate redun

dancy cabling. Set both controllers to test 28.

Stop pushbutton 2

29 Verifies proper pushbutton operation. Passes if after pressing the

stop pushbutton once, LED display changes from 0x29 to 0x55

with the red/green LED red.
