PRESENTATION
DESCRIPTION
MultiCOM 401 allows you to connect the UPS to a Profibus DP network. The device enables to
integrate, in industrial enviroment, the management and monitoring of the UPS into a control
system based on one of the most popular field bus designed especially for communication
between automation control systems and distributed I/O. Baud rates from 9.6 kbit/s up to 12 Mbit/s
are supported and automatically detected.
The device also offers an RS-232 serial line through which the UPS can be monitored using the
GPSER protocol (PRTK code: GPSER11201...).
• A: RS-232 communication port
• B: PROFIBUS connector
• C: power supply connector
• D: connector for connection to the UPS

OPENING THE PACKAGING AND CHECKING THE CONTENTS
After opening the packaging, first check the contents.
The packaging should contain:
MultiCOM 401
12Vdc 0.5A external power supply unit
DB9-RJ45 serial cable
CD-Rom (User manual and GSD file)
6
INSTALLATION AND CONFIGURATION
In order to access the DIP-switches and the jumpers, disconnect the device
from the power supply, remove the 4 screws on the base and then remove the
cover
ADDRESS CONFIGURATION
The Profibus address must be configured using the SW1 and SW2 rotary switch (shown in the
figure). Allowable addresses are 1÷99.
7
BUS TERMINATION AND BIASING
MultiCOM 401 is supplied with the bus termination and biasing resistors already mounted
internally (R=100Ω). Dip-switch SW3 must be closed in order to insert these resistors (see figure).
8
JUMPER SETTINGS
For proper working of the device, the jumper have to be set as shown in the figure below.
= closed
= open
CONNECTION TO THE UPS
Connect the “UPS SERIAL” port of the device to the serial port of the UPS using the cable supplied
with the UPS.
9
PROFIDRIVE MODE
The application can be drived in ProfiDrive standard compatible mode (ProfiDrive Mode). Driving
mode is selected by using the appropriate GSD file: RPS_0B74.gsd.
The gateway will accept all the configurations specified by Profidrive V2 (PPO1-PPO5).
Using the ProfiDrive mode the standard ProfiDrive procedures can be used and it is possible to
access to all application parameters in two possible ways:
1. Parameter area PKW: allow random access to any register in the range (1 – 799);
2. Process data area PZD: access automatically a predefined and configurable set of parameters.
CYCLIC COMMUNICATION (PROCESS DATA)
Cyclic communication data are exchanged with the Profibus DP master at every communication
cycle. The exchanged data format and length are specified at the initialization by Profibus DP
master using the Profibus DP configuration mechanism.
The supported configuration are:
Type Configuration bytes Process data layout
Profidrive V2, PPO1 0xf3 0xf1 PKW + 2 words PZD
Profidrive V2, PPO2 0xf3 0xf5 PKW + 6 words PZD
Profidrive V2, PPO3 0xf1 2 words PZD
Profidrive V2, PPO4 0xf5 6 words PZD
Profidrive V2, PPO5 0xf3 0xf9 PKW + 10 words PZD
The cyclic data consists of two parts, a parameter area (PKW) and a process data area (PZD).
The layout of the process data is:
PKW – 4 words PZD - 2÷10 words
PKE IND PWE PZD 1 PZD 2 PZD 3 PZD 4 PZD 5 PZD 6 PZD 7 PZD 8 PZD 9 PZD

10
The PKW part of the process data is used for asynchronous parameter access over process data.
The PZD words can be programmed to hold a value of any available parameter of the word type.
10
PKW-PART
The parameter part (PKW) is fixed to 4 words and can be used for reading and/or updating the
parameters in the application one by one. Requests and responses use the predefined handshake
procedure.
The PKW is further divided into three parts:
1. PKE: Parameter ID (2 bytes);
2. IND: Sub-index (2 bytes), 2nd byte isn’t used and should be set to 0;
3. PWE: Parameter value (4 bytes).

3. PNU: parameter number (11 bits).

In order to have different UPS parameters in PZD-part, the default configuration can be changed
by user as described below.
USER DEFINED PZD SLOTS
For configurations the standard parameters 915 and 916 are used to define which values are
transferred in these slots.
Parameter 915 defines output and 916 input direction. Both parameters 915 and 916 are of array
type and the subindex is used to reference the PZD slot (subindex 1 references PZD slot 1,
subindex 2 references PZD slot 2, ... subindex 10 references PZD slot 10). Parameters of type
word and byte can be selected (there is an implicit conversion byte-word). Not used PZD slots are
marked with 0 in the parameters 915 and 916.
EXAMPLES
Set input PZD3 with Input mains voltage V1 (index 12 [0x000C] UPS PARAMETER):
PKW
Output: 0x7394 0x0300 xxxx 0x000C
Input: xxxx xxxx xxxx xxxx
Word 0 → Index used 0x394 (916dec)
Word 1 → sub-index YY=03 (PZD3)
Word 3 → Value = index of Input mains voltage V1 in UPS PARAMETER table
Set input PZD10 with Battery voltage (index 48 [0x0030] UPS PARAMETER):
Word 0 Word 1 Word 2 Word 3
Word 0 Word 1 Word 2 Word 3
Output: 0x7394 0x0A00 xxxx 0x0030
Input: xxxx xxxx xxxx xxxx
Word 0 → Index used 0x394 (916dec)
Word 1 → sub-index YY=0A (PZD3)
Word 3 → Value = index of Battery voltage in UPS PARAMETER table
14
PERMANENT PZD CONFIGURATION
PZD configuration can be stored to non-volatile memory and automatically restored at the gateway
power up. For this purpose the internal gateway parameter 802 is provided. By writing to this
parameter the permanent storage of the PZD configuration is controlled. The possible values to be
written to this parameter are:
0 → none
1 → clear non-volatile PZD setting
2 → store the current PZD setting to non-volatile memory
3 → restore the PZD settings from non-volatile memory
The PZD setting saving is executed on the transition of the value of the parameter 802. To
generate this transition firstly store 0 to this parameter and then the desired value.
Ones that there are stored PZD settings in non-volatile memory, the function 3 (restore) is
automatically executed at the gateway power up. In order to stop this auto-initialization the value 1
has to be written to parameter 802.
EXAMPLES
Store PZD setting to non-volatile memory:
Word 0 Word 1 Word 2 Word 3
Output: 0x2322 xxxx xxxx 0x0002
Must be 0 before.
So write 2 and after 0
Word 0 → Index used 0x322 (802dec)
Word 3 → Value = 2 (store the current PZD setting to non-volatile memory)
Reset PZD setting to non-volatile memory:
Word 0 Word 1 Word 2 Word 3
Output: 0x2322 xxxx xxxx 0x0001
Must be 0 before.
So write 1 and after 0
Word 0 → Index used 0x322 (802dec)
Word 3 → Value = 1 (clear non-volatile PZD setting)
