Introduction

The "GTC link" communication interface is designed to transmit

MGE

operating information and remote "on/off" commands (if available) to an external computer.

The JBUS hexadecimal communication protocol is used (the JBUS ASCII mode is not used in this application).

The "GTC link" features two symmetrical communication channels, both with a simplified V24 (RXD and TXD only) and an RS485 interface.

It consists of a "GTCZ" communication board (central unit) and a "RAUZ 1" (communication network management and interconnection board). In option, two additional communication ports can be added: "GT2Z" board (central unit) and "RAUZ 2" board (communication network management and interconnection board). Refer to the "communication options connection manual" of

MGE

6739388XU, for all informations about connections.

"GTCZ" and "GT2Z" boards features

The "GTCZ" and "GT2Z" boards are functionally divided into two main modules:

The ACQ module

◗ performs data acquisition; ◗ monitors the status bus of the

monitor/control boards;

◗ computes physical quantities and

battery backup time;

◗ processes alarms; ◗ sends commands to monitor/

control boards;

◗ stores configurable parameters

and communicates with the "Soft Tunor" software, used by APC by Schneider Electric after-sales service;

◗ transfers data using the on-board

communication channels.

The COM module

The COM communication module is designed for external devices (e.g. "AMUZ" type board of a "Monitor" or "Tele-Monitor") to:

◗ retrieve information and

parameters processed by the ACQ;

◗ send commands to monitor/

control boards;

◗ be integrated into other systems

(remote indications and supervision).

Each "GTCZ" or "GT2Z" board is equipped with two symmetrical communication ports, COM1 and COM2:

◗ on the "GTCZ" board:

◗ ◗ COM1 for a "display devices"

network consisting of "AMUZ" boards in a unitary or parallel connected UPS configurations,

◗ ◗ COM2 for a supervisory system;

◗ on the "GT2Z" board:

◗ ◗ COM1 and COM2 for a

supervisory system.

The "GTCZ" and "GT2Z" boards are configured with the APC by Schneider Electric after-sales customization software called "Soft Tunor". The computer link is via the test connector located on the front panel of the cubicles and performs:

◗ configuration, calibration and

control of the ACQ module;

◗ configuration of COM1 and

COM2 ports.

Page 4 - 6739389EN/FB

Communication settings

The COM1 and COM2 communication ports can be configured as follows:

◗ data rate: 1200, 2400, 4800,

9600 Baud;

◗ data bits: 8 (always); ◗ parity: none, odd, even; ◗ stop bits: 1 or 2;

Location of the "GTCZ" and "GT2Z" boards in the cubicle electronics

◗ slave address: 20H to F8H in

increments of 8H;

◗ interface:

◗ ◗ 0 = RS232 simplified, ◗ ◗ 1 = RS232 complete

(not implemented),

◗ ◗ 2 = RS485;

◗ command masks; ◗ other parameters (modem type,

telephone number, handshaking, modem protocol, password) reserved for later use.

JBUS protocol

Introduction

JBUS protocol can be used to read or write one or more bits or words. In the interest of simplicity, this document describes only the procedures necessary for operation and monitoring of the APC by Schneider Electric unit.

Communications are initiated by the master and include a request from the master and a response from the slave.

Master requests must be addressed to one specific slave (identified by its address in the first byte of the request frame) as shown in the diagram opposite:

JBUS protocol (continued)

Principle

A full understanding of the protocol is only required if the master is a computer that must be programmed.

All communications include 2 messages: a request from the master and a response from the slave.

Each message or frame containes 4 types of information:

◗ slave address (1 byte)

The slave address specifies the destination station (see address list):

◗ ◗ unitary rectifier-inverter cubicle, ◗ ◗ parallel rectifier-inverter cubicle, ◗ ◗ Static Switch cubicle.

If zero, the request addresses all slaves and there is no response message (in which case it is a broadcast message, a function not used in this application);

◗ function code (1 byte)

Selects a command (e.g. read or write a bit or a word) and checks that the response is correct. The JBUS protocol comprises 10 functions of which 3 may be used in this application: function 3 (read n output or internal words), or function 4 (read n input words), or function 16 (write n words);

◗ information field (n bytes)

The information field contains the parameters related to the functions: bit address, word address, bit value, word value, number of bits, number of words;

◗ check word (2 bytes)

A word used to detect transmission errors.

Synchronizing data exchanges

Any character received after 3 or more character lengths of silence is interpreted as the start of a frame. Therefore, a minimum silence of 3 character lengths between frames must be respected.

Description of request and response frames

request

This function code selects one of 10 possible commands:

- Function 1 : read n output or internal bits

- Function 2 : read n input bits

- Function 3 : read n output or internal words

- Function 4 : read n input words

- Function 5 : write one bit

- Function 6 : write one word

- Function 8 : data exchange diagnostics

- Function 11 : read event counter

- Function 15 : write n bits

- Function 16 : write n words

JBUS protocol (continued)

Checking received messages on the slave side

After the master sends a request containing the slave address, the function code and data, it computes the CRC and sends it as the check word (CRC 16). When the slave receives the request, it stores the message in memory and calculates the CRC 16 to compare it to the received CRC

16.

If the message is incorrect (unequal CRC 16 values), the slave does not respond. If the message received is correct but the slave is unable to process it (incorrect address, incorrect data, etc.), the slave returns an error message with the following contents (see opposite):

6739389EN/FB - Page 11

JBUS protocol (continued)

Function 11: reading event counters

The master and each slave have one event counter. This counter is incremented each time a frame is received and interpreted correctly by the slave (except for function 11 itself). A correctly transmitted message increments the counter. If the slave sends an exception response, the counter is not incremented.

The master can read the counter to determine whether or not the slave correctly interpreted the command (incremented the counter or not).

UPS theory of operation

Unitary UPS

The unitary MGE

GalaxyTM 6000

UPSs are made up of five modular sub-assemblies:

Mains 1 power up

◗ the inverter receives power from

the rectifier-charger and supplies power to the load. There is no direct connection between Mains and load;

◗ the battery is charged or the

charge maintained.

Mains 1 power down

◗ the inverter receives power from

the battery and supplies power to the load;

◗ the battery discharges.

◗ rectifier-charger; ◗ battery; ◗ three-phase inverter; ◗ static switch; ◗ maintenance bypass.

Major overload

◗ Mains 2 supplies power to the

load via the static switch;

◗ the inverter is shut down; ◗ the inverter starts-up

automatically as soon as overload is removed;

◗ power is transferred without

affecting the load.

Maintenance

◗ Mains 2 supplies power to the

load via the maintenance bypass;

◗ the rectifier-charger and inverter

are shut down and disconnected from all sources of power.

Parallel connected UPS with "Static Switch"

Up to six parallel connected rectifier-inverter cubicles can be combined with one "Static Switch" cubicle to form a system that operates like a unitary UPS system. Each parallel connected rectifierinverter cubicle houses a:

◗ rectifier-charger; ◗ battery; ◗ three-phase inverter.

The "Static Switch" cubicle contains:

◗ static by-pass switch; ◗ maintenance bypass.

The units have separate batteries:

Every bit is listed according to the following format:

bit address: description (bit = 0 / bit = 1).

Word address: 40

400: battery circuit breaker (0=open/1=closed)

Battery protection circuit breaker "QF1" is located near the battery and is "on" (closed) during normal operation. When it either trips or is turned "off" (open) the load is no longer protected since battery power is no longer available if Mains 1 fails.

401: battery discharging (0=not discharging/1=discharging)

The inverter powers the load. Mains 1 is either not available or outside tolerances and the inverter is battery powered.

402: minimum battery voltage (0=not reached/1=min. volt. fault)

A fault indicates that the minimum battery voltage has been reached during Load on battery and the inverters it supplies are stopped. If Mains 2 is not available, which is generally the case, the load not longer receives power.

403: low battery shutdown warning (0=not reached/ 1=warning)

The warning indicates that the end of backup time is imminent. It is only applicable when the inverters operate on battery power.

404: battery temperature (0=normal/1=outside tolerances)

This information only exists if the system is equipped with the "Temperature Monitor" option. It tells the user that the temperature of the battery is outside the allowable range.
