Introduction
The "GTC link" communication
interface is designed to transmit
MGETM GalaxyTM 6000 UPS
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
MGETM GalaxyTM 6000 nr
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.
6739389EN/FB - Page 5
Communication settings
◗ command masks;
◗ other parameters (modem type,
telephone number, handshaking,
modem protocol, password)
reserved for later use.
◗ slave address: 20H to F8H in
increments of 8H;
◗ interface:
◗ ◗ 0 = RS232 simplified,
◗ ◗ 1 = RS232 complete
(not implemented),
◗ ◗ 2 = RS485;
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;

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);
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.
◗ 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.

When the message is
received, the slave reads

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
information requested: bit/word address,
bit/word value, bit/word number.

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):

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).
These functions can be used to
diagnose the data exchange taking
place between master and slaves.
If the master counter equals the
slave counter, the slave executed
the command sent by the master.
If the master counter is one higher
than the slave counter, the slave
did not execute the command sent
by the master.

UPS theory of operation
Unitary UPS
The unitary MGETM GalaxyTM 6000
UPSs are made up of five modular
sub-assemblies:
◗ rectifier-charger;
◗ battery;
◗ three-phase inverter;
◗ static switch;
◗ maintenance bypass.
The load and Mains 2 operate at 50
or 60 Hz.
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.

Parallel connected UPS with "Static Switch" cubicle
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 rectifier-
inverter cubicle houses a:
◗ rectifier-charger;
◗ battery;
◗ three-phase inverter.
The "Static Switch" cubicle
contains:
◗ static by-pass switch;
◗ maintenance bypass.

the same sub-assemblies:
◗ rectifier-charger;
◗ battery (option);
◗ three-phase inverter.
They may or may not be parallel
connected depending on type and
may or may not contain a battery.
The output voltage has a frequency
of 50 or 60 Hz.

System information
Message format
This section describes the
messages exchanged between the
"GTC link" communication interface
and the external computer based
on the JBUS protocol.
The length of time after which a
message must be interpreted as
"not understood" depends on the
type of command sent.
The table opposite lists maximum
response times:
Data rate 1200 Baud 2400 Baud 4800 Baud 9600 Baud
status information only 0,5 s 0,25 s 0,12 s 0,06 s
all measurements 2 s 1 s 0,5 s 0,25 s
Response time of event (independent of data rate)
- inverter start-up and connect : 30 s
- rectifier-charger startup : 30 s
- rectifier-charger or inverter stop : 30 s
For the "responses", refer to the

(data words at address 40 to 4E)
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. The rectifier-
charger circuit is switched so that
the battery charging current
becomes zero. The battery is no
longer being recharged (battery
protection).
405 : Mains 1 voltage (0=normal/
1=outside tolerances)
Indicates that the Mains 1 power
supply voltage is outside tolerances
and the inverter on battery power.
406 : battery room ventilation
(0=no fault/1=fault)
Informs the user of a battery room
ventilation fault. The rectifier-
charger circuit is switched so that
the battery charging current
becomes zero. The battery is no
longer being recharged. It prevents
vented led-acid batteries from
giving off hydrogen gas The user
must remedy the ventilation
problem.
407: battery charging (0=not
charging/1=charging)
Informs the user whether the
battery is currently being recharged
(only valid for vented lead-acid
batteries).
408: rectifier-charger status
(0=off/1=on)
Gives the status of the rectifier-
charger circuit. It stops every time
Mains 1 power fails. In this case the
load is battery powered via the
inverter.
409: major rectifier-charger fault
(0=no fault/1=fault)
Informs the user of a major rectifier-
charger fault requiring after-sales
servicing.
40E: Mains 1 input switch
(0=open/1=closed)
"Q1" Mains 1 input switch which
powers the rectifier-charger.

411: emergency off switch (0=not
activated/1=activated)
Normally-closed switch connected
to the units. When activated, the
rectifier-charger circuits and the
inverters stop operating. The "QF1"
battery circuit breaker is also
opened.
If the "emergency off" also tripped
the protection devices to
disconnect the units from Mains 1
and Mains 2, the load no longer
receives power and the units are
completely disconnected.
412: rectifier-charger input
voltage (0=normal/1=outside
tolerances)
The rectifier-charger stops
operating when the Mains 1 phase-
to-phase voltage is outside
tolerances.
413: rectifier-charger input
frequency (0=normal/1=outside
tolerances)
The rectifier-charger stops
operating when the Mains 1
frequency is outside tolerances.
417: gradual rectifier-charger
shutdown (0=not activated/
1=activated)
Indicates that the rectifier-charger
received an external command to
gradually stop operating (e.g.
gradual load-shedding when using
power from engine generator sets).
419: engine generator set current
limiting (0=not activated/
1=activated)
Informs the user that the rectifier-
charger has received an external
command to limit the current drawn
from Mains 1. The additional power
required by the inverter is supplied
by the battery (which discharges).
Example: operating from a
generator that delivers insufficient
power.
41A: battery current limiting
(0=not activated/1=activated)
The rectifier-charger received an
external command to limit the
current that charges the battery.
Normal battery charging is resumed
when Mains 1 returns.
Example: operating from a
generator that delivers insufficient
power to supply load and charge
batteries.
Note: the current limit is
programmable.
6739389EN/FB - Page 35
System information (continued)
41B: battery equalization (0=not
active/1=active)

in parallel with the static switch on
the Mains 2 line on certain high
output units. It is installed in static-
switch cubicles with power ratings
over 400 kVA.
496: Mains 2 input switch
(0=open/1=closed)
Switch "Q4S" is located on the
Mains 2 phases at the input of the
static switch (on the bypass line).
The switch is normally closed.
497: maintenance bypass switch
(0=open/1=closed)
Switch "Q3BP" bypasses the static
switch and connects Mains 2
directly to the load. This switch is
normally open. When closed (with
"Q4S" and "Q5N" open), the load
can continue to be powered while
the UPS is isolated for servicing.
498: inverter output switch
(0=open/1=closed)
Switch "Q5N" is located at the
output of the inverter and is used to
disconnect the load from the
inverter (or from the output busbars
when several units are connected
in parallel).
This switch is normally closed.
499: static switch status
(0=open/1=closed)
The static switch on Mains 2 is
normally open (inverter powers the
load). The load is transferred to
Mains 2 by closing the static switch
when the inverters are no longer
capable of delivering the required
power (overload, end of backup
time or internal error).
49C: Mains 2 frequency
(0=normal/1=outside tolerances)
When the frequency of Mains 2 is
outside tolerances, load transfer
from inverter to Mains 2 will include
an interruption of 0.8 s or will not
take place.
49D: Mains 2 voltage (0=normal/
1=outside tolerances)
When the phase-to-phase Mains 2
input voltage is outside tolerances,
load transfer from inverter to Mains
2 will include an interruption of 0.8
second.
49F: free-running frequency
request (0=not activated/
1=activated)

interrupt prohibited (0=not
activated/1=activated)
An auxiliary command prohibits
transfer to Mains 2 with power
interruption.
4A5: transfer lockout (0=not
activated/1=activated)
The inverter received an auxiliary
command prohibiting transfer to
Mains 2. The load is totally
dependent on inverter power. If the
inverter stops (internal fault), the
load will no longer receive power.
4AF: inverter quantity
(0=insufficient/1=sufficient)
This only concerns systems with
parallel connected inverters and a
static switch cubicle. It informs the
user that the number of inverters to
be connected to the load is
insufficient to supply the necessary
power. Additional inverter(s) must
be turned on so that the inverters
can start supplying the power to the
load. If this is not the case, Mains 2
continues to supply the power.
Word address: 4C
(summary of operating
information)
4C0: acquisition fault (0=no fault
/ 1=fault)
Indicates an acquisition fault for the
internal analogue or logic values of

time" is less than the amount
configured in the unit.
4C2: end of battery life (0=no
fault / 1=end of battery life)
Indicates that the battery has
reached its maximum service life
and should be replaced.
4C4: system normal, load
protected (0=not normal/
1=normal)
Indicates that the inverter powers
the load and that the full battery
backup time is available if Mains 1
fail. The unit is operating normally.
Note: for parallel connected inverter
cubicles, this only refers to the
output power supplied by that
specific unit. The load may be
unprotected if more than one inverter
is required to supply the load power.
All required inverters in the system
or the static switch cubicle if it exists
must therefore be checked.
4C5: system downgraded due to
malfunction (0=not downgraded/
1=downgraded)
Indicates a malfunction or
environment fault; nevertheless the
inverter can still power the load.
