Exchange of 88TK50 modules in case of

dual---channel station---bus coupling

In the case of a dual---channel station ---bus coupling, bump-

less exchange of modules is possible on ---line and without any

impairment of the ongoing station operation provided that the

module is in the PASSIVE state.

The PASSIVE state is indicated by the following LED annuncia-

tion on the module front:

LED designation

Operating state

FDDI receiving

FDDI sending

Procedure for module exchange:

1. The module to be replaced must be withdrawn while being

in the PASSIVE state, with the optical cables connected.

2. Then, the optical cables have to be removed.

3. Plug the optical cables onto the new module.

4. Now, the new module may be plugged into its module slot,

the optical cables being connected.

WARNING!

It is not admissible to withdraw a 88TK50 module without the

optical cables being connected.

A second 88TK50 module may be installed into a station only

after the 88TK50 module, which already exists in that station,

has reached its ACTIVE state.

The ACTIVE state is indicated by the following LED signals on

the module front:

LED designation

Operating state

Improper handling may cause failure of the station operation.

Diagnosis and annunciation functions

Disturbance annunciation signals to the annunciation

system

The annunciation system and/or the control diagnosis system

(CDS) receives the disturbance annunciation signals of the

module via the PROCONTROL remote bus (FDDI interface).

They also include message 'General disturbance of station

detected' generated from the individual signals of the station

modules.

The 88TK50 transmits its disturbance annunciation signals and

diagnosis results in 2 diagnosis registers using register

LED signal

address 246.

OFF

The contents of both diagnosis registers are transmitted at the

beginning of each cyclic call, and thus are stored in the cyclic

OFF or

send shared memory for being sent via the FDDI system inter-

FLASHING

face.

Sequence:

--- Diagnosis register for module address 60 in the case of

single ---channel station ---bus coupling or

Diagnosis register for module address 60 or 61 in the case

of dual---channel station ---bus coupling,

--- Diagnosis register for module address 62

In the event mode, event messages of the 88TK50 are trans-

mitted over the station bus and thus are stored in the event---

send FIFO for being sent via the FDDI system interface.

The following types of disturbance are detected:

1. Internal module disturbances

2. Disturbances in data communication over the station bus

and the PROCONTROL remote bus (FDDI interface)

3. Disturbance signals of other station modules (in the form of

'General disturbance of station detected')

4. Disturbance signals from the monitoring interface.

All types of disturbance lead to an activation of the binary

signal output MST.

The types of disturbance (1 ... 3) are indicated on the front

LED signal

panel of the module (cf. chapter 'Disturbance annunciations

on the module').

STEADY LIGHT

Disturbance type 4 is indicated through signal MST.

The contents of the diagnosis registers, the messages on the

CDS and the annunciations ST and SG are shown in Figures

1 ... 2.
