Type of connection using direct connection on site via protocol of ports on the controller. Length of
connection is given by protocol specification.
Remote connection
Type of connection using standard communication lines such as Internet, modem connection and
GSM connection for communication between controller and other superior device.
Comap Protocol
Communication between PC with ComAp software (InteliMonitor, GenConfig) and controller is running
on this protocol.
3rd party software
Software using standardized protocol for sharing of data between particular systems (for example
ModBus RTU, ModBus TCP etc.).
Single gen-set communication
This type of connection allows communication only with one controller. Communication with other
controllers on site via this type of connection is not possible.
Multiple gen-set communication
This type of connection allows communication with more than one controller on site via single
communication link.
Monitoring
Type of communication used for continuous displaying of process data and process control of the
system.
Configuration
Type of communication used for writing of configuration file into the controller.
Note:
There are used some abbreviations for resolution of all hardware variations of IGS-NT controllers in
this document. These abbreviations correspond with order codes of each HW variation.
Direct USB connection is not possible for some controllers, however USB connection is available for
all mentioned controllers via external bridge I-LB+.
Direct RS485 connection is not possible for some controllers, however RS485 connection is available
for all mentioned controllers via external bridge I-LB+.

(Setpoints/Comms settings group)
Equipment
Hint:
RS485 connection can be used for gen-set control for longer distance. IG-NT-BB has no possibility of
direct connection to RS485 bus. This controller provides RS232 port only. External converter from
RS232 to RS485 is needed.
The Internet (Ethernet) connection is a point-to-point connection between a PC and a controller or site
via an TCP/IP protocol-based network. The physical configuration of such network can be a small
local area ethernet network as well as the Internet.
Controllers
Hint:
Ethernet connection is available for all mentioned controllers via external bridge IG-IB or IB-NT (see
the chapter Ethernet connection via IG-IB/IB-NT).
Number of clients connected simultaneously
2 clients with InteliMonitor or WebSupervisor (Comap/TCP protocol)
2 clients with web interface
Using a web browser
Ethernet connection to controller makes possible using any web browser for basic monitoring and
adjustment of the controller. Simply put the IP address of the module into the address line in your web
browser like http://192.168.1.254 and then enter access code. In case of connection from web
browser there is 5 minutes timeout after closing the browser window. After that the client is
automatically logged out.
Ethernet connection settings
Parameters can be set via any type of connection (USB, RS232, Ethernet). Setup is provided via
InteliMonitor. For Ethernet connection set these parameters in Comms Settings group:
Ethernet cable to LAN, for point to point connection
between PC and controller use cross-wired cable
PC side
ETHERNET connection
The IP addresses of the controllers must be accessible from the remote computer. If the remote
computer is connected into another LAN segment than the gen-sets are, there must be a gateway(s)
that enable direct traffic between the segments. If the remote computer is connected via Internet, then
the internet gateway of the LAN where gen-sets are connected must have public IP address, must
allow incoming traffic and must provide port forwarding from the external public IP to the different
internal gen-set IPs according to the port used.

Modbus/TCP access code
Every Modbus/TCP session has to be started with writing the access code from the modbus/tcp client
to the controller. If the session is closed and reopened again the access code must be written again.
The session can be closed by the client or the controller closes the session automatically if there is no
activity from the client side for 15s.
- There are new dedicated registers for entering the AccessCode via Modbus/TCP.
- The register numbers are 46339-46346 (register address 6338-6345).
- The previous method using register address 24535 remains working as well.
- Example of the Modbus message is following (in HEX):
01 Controller address
10 Modbus function (16dec – Write multiple registers)

Using a web browser
Ethernet connection to controller makes possible using any web browser for basic monitoring and
adjustment of the controller. Simply put the IP address of the module into the address line in your web
browser like http://192.168.1.254 and then enter access code. In case of connection from web
browser there is 5 minutes timeout after closing the browser window. After that the client is
automatically logged out.
NOTE:
The IP addresses of the controllers must be accessible from the remote computer. If the remote
computer is connected into another LAN segment than the gen-sets are, there must be a gateway(s)
that enable direct traffic between the segments. If the remote computer is connected via Internet, then
the internet gateway of the LAN where gen-sets are connected must have public IP address, must
allow incoming traffic and must provide port forwarding from the external public IP to the different
internal gen-set IPs according to the port used.
INTERNET GATEWAY CONFIGURATION EXAMPLE (PORT FORWARDING)
This connection type is used for connection to controllers/sites, that are connected to the Internet,
however they do not have public and static IP address. The controllers connect by themselves to the
AirGate server and cyclically ask whether there is a connection request from a client or not. On the
other side the clients (InteliMonitor, WebSupervisor) connect to the AirGate server instead of
connecting directly to the controller. The server then creates a "tunnel" between the client and the
controller. Internet connection via AirGate server is supported by controllers IG-NTC-BB and IS-NTCBB with ethernet connection possibility. The connection to ethernet is realized the same way as
remote ethernet connection.
CAUTION!
To avoid unauthorized access to the controller change the access code and keep it secret!
PRINCIPLE OF AIRGATE CONNECTION
Airgate connection settings
Parameters can be set via any type of connection (USB, RS232, Ethernet). Setup is provided via
InteliMonitor. For ethernet connection set these parameters in Comms Settings group:
Connection via AirGate is supported by controllers with direct connection to LAN only or via IB-NT
module. Airgate connection is not available for connection via IG-IB module.
Connection to InteliMonitor via AirGate server
1. Select the AirGate connection type.
2. Fill-in the correct AirGate ID for each controller.
3. Enter the AirGate server address.
Hint:
You will obtain the AirGate ID by the registration of the particular controller on the AirGate server. Set
all setpoints in Comms Settings group according to AirGate connecgtion settings and connect
controller to LAN. Controller AirGate ID will be viewed on the screen.
NOTE:
This function is available in InteliMonitor ver. 2.6 and higher. Please watch the ComAp web site for
detailed information.
NOTE:
Although the controllers in your site are not connected together by the CAN2 bus they must have
different controller addresses.
WebSupervisor is web based system designed for monitoring and controlling ComAp controllers via
the internet. This system offers a number of beneficial features that help optimize revenue for
machinery fleets, as each piece of equipment can be individually monitored for all important operation
values.
Connection of controllers with direct Ethernet port can be realized two diferent ways:
1. Internet connection via AirGate: No fixed and public IP address is needed. Connect
and set the controller the same way as for Internet connection via AirGate.
2. Internet connection without AirgGate: Controller has to have fixed and public IP
address. Connect and set the controller the same way as for Ethernet Connection
(Direct).
Connection of all controllers can be realized using IG-IB external bridge. Connect and set the
controller the same way as for Ethernet (Internet) connection via IG-IB module.
The web interface is intended to monitor the controller from a web browser. Static IP address is
required for this function as you must know the IP address to put it into the browser. Public IP address
or port forwarding is required if you want to see the web pages from the Internet.
PORT FORWARDING EXAMPLE FOR WEB CONNECTION
The web server is designed for basic monitoring and adjustment of the controller using a web browser.
Put the Controller IP address into the browser. You will be asked for the controller access code prior
to entering the controller web.
NOTE:
The web server is optimized for IE6 or higher and screen resolution 1024x768 pixels.
CAUTION!
Do not use the browser navigation buttons as "Back", "Forward" or "Reload". Use the links and the
reload button located in the toolbar instead.
Click to the SCADA link in the toolbar to display the scada page. The scada page is also the main
page which is displayed by default if you just put the controller address into the browser.
NOTE:
The scada page layout may differ according to the firmware branch, version and application. Certain
old firmware versions does not support web access at all.
Measurement
Click to the MEASUREMENT link in the toolbar to display the measurement page. Then click to the
required group name in the left box to display values of the group in the right box.
NOTE:
The measurement page is automatically refreshed every 60 seconds.
Click to the SETPOINTS link in the toolbar to display the setpoints page.
Click to the required group name in the left box to display setpoints of the group in the right

Click to the required setpoint name or value to change the value. If the respective setpoint is
protected by password, which is indicated by a lock icon by the setpoint name, you have to
click on the "Controller password" icon located in the toolbar and then enter valid password.
NOTE:
The setpoint page is automatically refreshed every 60 seconds. If an another user changes a setpoint
from other terminal, the web page will not show this change immediately as e.g. InteliMonitor.
Click to the HISTORY link in the toolbar to display the history page.
Use the control buttons to move within the history file.
NOTE:
The history page is automatically refreshed every 5 minutes. If a new record appears in the controller,
the web page will not show it immediately as e.g. InteliMonitor.
Click to the "Webserver settings" icon in the toolbar to display the settings page.
Select the controller language the web pages will appear in.

Internet connection via cellular network
Connection via Internet bridge IB-NT
What is InternetBridge-NT?
InternetBridge-NT is a communication module that allows connection of a single controller as well as
whole site to the Internet or Local area network. The connection to the Internet can be via built-in
cellular modem supporting 2G and 3G networks or Ethernet cable.
The module can be used for controllers from following product lines: IG-NT, IS-NT and IC-NT.
NOTE:
For proper operation it is necessary to update the controller firmware to a version which supports IBNT. For IG-NT and IS-NT standard branch the first version supporting IB-NT is 2.6.
For more information about IB-NT read IB-NT-2.0-Reference Guide.pdf.

Comms extension - I-LB+ Local bridge
Description
I-LB+ is communication modules for communication with all devices connected to CAN(2) bus. I-LB+
is successors of the IG-MU unit designed to be used with IG/IS controllers. It therefore provides
additional communication port and higher communication speed. Speed for direct/modem connection
can be up to 57600 bps (IG-MU only 19200 bps). I-LB / I-LB+ can be connected with PC via USB,
RS232 or RS485. I-LB is without USB port, I-LB+ is with USB port (speed ≈ 115200 bps).
One IG-IB is connected to each controller via RS232 for faster communication. It means that up to 32

In this case no dongle is necessary.
One unit could be also connected via CAN interface.
Two controllers – CAN / Ethernet connection
The dongle must be used. The type of IG-IB dongle limits number of accessible controllers (up to 32).
Dongles for up to 3, 7, 15 and 32 controllers are available. See also IG-IB Dongle
Max four PCs can be connected to one iG-IB at once
controllers are used with intercontroller CAN bus and monitored via IG-IB or I-LB units, the reaction on
commands issued from InteliMonitor or other monitoring SW can be delayed up to several seconds.
The same holds for values reading, i.e. refresh of measured power etc. in InteliMonitor or other PC
SW.

Internet Bridge can be connected to Internet
via LAN – Ethernet connector or
via dial up – MODEM connector.
Maximal length of UTP cable (between IG-IB and Switching hub) is 100m according to IEEE 802.3.
Corresponding firmware must be downloaded to IG-IB depends on required connection type.
For IG-IB V2.5 firmware configuration use IG-IB configuration tool (IBConfig.exe) at least V1.2 or
higher. IBConfig of V1.2 can be used for IG-IB firmware 1.0 and 1.1 as well.
For IG-IB V2.1 firmware configuration use IBConfig at least V1.4 or higher.
Hint:
You cannot update firmware in IS-Display terminal by means of IG-IB version 2.0 and lower. Available
support for IGS-NT is in IG-IB 2.1 and higher. In case you use 2.0 version, the message appears
(Access not allowed (object 24431)) because IG-IB is not able to work with IS-Display.

Please notice:
Setting CAN-Addr.1 was interchanged with setting CAN-Addr.2 starting with IBConfig-1.6. It
means that IG-IB’s CAN address has to be set to CAN-Addr.2, if I-LB which is set to the address
ADR1 is connected to the same CAN bus as IG-IB. Use option CAN-Addr.1 if I-LB is set to ADR2.
It is necessary to set IG-IB's CAN address using IBConfig-1.5 in this way: IG-IB’s CAN address has to
be set to CAN-Addr.1, if I-LB which is set to the address ADR1 is connected to the same CAN bus as
IG-IB. Use option CAN-Addr.2 if I-LB is set to ADR2.

If iG-IB is to be visible from the Internet, then your IT manager should create a communication channel
on the Internet access server.
The iG-IB uses the TCP-communication and listens at the port 23 (known as Telnet port).
Hint:
Some providers have strict requirements for e-mail iG-IB Mailbox address = existing mailbox.
Use firmware V2.0 and higher for dialup connection.

After e-mail is successfully sent, waiting for operator response.
If checked connection to ISP is never terminated.
It is established immediately after IG-IB is initialized. If the
communication is interrupted, it is re-established. It is necessary
that the IP address of IG-IB is static so that the PC software
(e.g. WinEdit) “knows” to which address to re-connect.
If this option is not selected, the connection to ISP is
established on request from terminal only. IP address obtained
from ISP is then sent to the terminal via email (IP address can
be dynamic in this case).

Connection is opened for “Connection holding time” after e-mail is successfully sent.
Note for iG-IB firmware version 1.0 or 1.1 users: active e-mail sending may fail if selected SMTP
server returns a multiline responses. Use firmware version 2.0 to solve this problem.

Hint:
From IG-IB-2.1 the dongle sets the limit of number of connected controllers. If the controller is
connected via RS232, the address 1 is supposed. Currently it is possible to order only dongle IG-IB32
as replace for all others dongles that got obsolete.
Internet Connection Diagnostics
Following method is Comap PC SW independent way how to check connection from PC via Internet to
some controller.
The basic diagnostic of iG-IB to internet connection could be done using telnet software:
1) Start telnet software
2) In telnet window write command „open xxx.xxx.xxx.xxx“
3) If the connection is OK, you should get a nontext (binary - firmware version) answer. Depending
on the font you use in the telnet window correct message looks like:
Hint:
Telnet software is included in standard Windows installation. To run telnet use Windows Start – Run
button and write “telnet”, OK.
The solution principle is shown in attached picture. All addresses in this text and in the picture are
fictive and will be different on real installation, port numbers are real. If the network software is
configured as shown in picture, users from Internet will be able to connect from Comap PC SW to
address 195.122.194.89 and communicate with IG-IB behind firewall. So in fact, we enter to PC SW
different address than is configured in IG-IB, as is correctly noted in the manual.
Needed changes are these:
1. DHCP server in private network (if used): exclude address 192.168.1.250 from the address poll
which are available to lease from this server, so that this address couldn't be assigned to any device in
the network. This will make this address available for use by IG-IB.
2. Firewall: Configure transparent proxy channel from external interface 195.122.194.89, port 23 to
protected network, internal address 192.168.1.250, port 23. This transparent proxy will do all network
address translation needed when communicating from public network with internal private network.
Port 23 on interface 195.122.194.89 should be usually free for this use, as normally is this port used
for telnet service and telnet is considered dangerous to use on firewalls.
I-CR Module for CAN Bus Extension
If the distance between units is too high to fit into the 200 m limit (or 900 m for 8 controllers), CAN
repeater module (I-CR) can be used to extend it.
Typical case – in line extension:

total segment length up to 900 m
total segment length up to 200 m

This connection allows PC communication to all controllers in the system (e.g. via InteliMonitor),
including a distant InteliMains unit.
I-CR module functions:
- Intercontroller CAN bus extension (one or more I-CR modules can be used).
- Intercontroller CAN bus bus-tie bridging – makes groups of controllers in segments A and B
“invisible” one for another depending on bus-tie breaker state, keeping the PC communication (ILB, IG-IB) in function for all controllers.
- Peripheral CAN bus extension
I-CR configuration jumpers:
P2 – Forces 250 kbps mode (32C) on CAN A, otherwise speed autodetection is used.
P3 – Forces 250 kbps mode (32C) on CAN B, otherwise speed autodetection is used.
P4 – Activates Filter mode (bus-tie bridging).
P5 – Forces alternate controller address 3 for bus-tie status reading (default controller address is 4).
P10 – If “H” network configuration used (two I-CR units), it must be switched to RS-422 mode.
I-CR indication and diagnostic LEDs:
For more detailed information about I-CR, see the Application sheet “Extending the CAN bus” or
IGS-NT-x.y-Installation guide.pdf.
Hint:
CAN bus has to be terminated at both ends.
In the case of surge hazard (connection out of building in case of storm etc.) see the “Recommended CAN/RS485 connection” chapter of the IGS-NT-2.4-Installation guide.pdf.

This module is intended to provide CAN bus redundancy in applications where IG/IS-NT controllers
are placed in several switchboards that need to be interconnected by the CAN bus communication line
and where there is essential to keep the line working. As a side effect, the module also provides the
CAN bus line extension.
As the CAN bus provides data exchange needed for Load Sharing and VAr Sharing and also for
Power Management features, it’s redundancy can be very important in complex systems with more
engines, more mains incomers.
The module is based on I-CB/CAT GAS HW. This HW needs to be bought and then it’s standard FW
replaced with I-CR-R FW obtained from ComAp Download Center. Also, for the replacement of the
FW, you will need the FlashProg utility which can be downloaded in Peripheral Modules Upgrade
Package here: http://www.comap.cz/support/download-center/type/software/. Chapter related to I-CB
reprogramming is to be used.
Hint:
I-CR-R may be used as a redundancy module for a maximum of 20 controllers (counted all controllers
on the CAN2 bus).
For usage I-CR-R in an installation of more as 20 controllers please contact our technical support for
another redundancy solution.
Typical case – several controllers, each one in separate switchboard:
Note: If I-LB (or other bridging module) is to monitor all the site, it is recommended to place it at the
position 1. If there is preferably monitored one group (within one switchboard) and the other controllers
not at all or only seldom, option 2 is more suitable. Remote connection to let’s say controller 7 is
possible in this case but data transfer will be quite slow.
- Intercontroller CAN bus redundancy – basic description of terminology used: o Local CAN bus – a bus going from the module to the local controller(s) = within one
switchboard; name on the sticker CAN1 CONTROLLER; in standard installation (with no
redundancy) this would be the intercontroller bus (CAN2)
o Primary intercontroller CAN bus – a bus interconnecting all I-CR-R modules and
providing 1 to 1 replacement of standard intercontroller CAN bus (CAN2); name on the
sticker CAN EMS
o Backup intercontroller RS485 bus – secondary bus interconnecting all I-CR-R modules;
transmits only intercontroller communication (Load Sharing, VAr Sharing, Power
Management), not the remote communication (I-LB, IG-IB connection to a PC monitoring
tool)
- The module preferably uses the Primary CAN bus line for data transfer. However, if the
connection from any of the controllers connected to other I-CR-R modules is broken the module
automatically re-routes it to the Backup RS485 line and continues in operation. From controllers’
point of view, no data transfer interruption is observed.
- It is possible to indicate the problem with Primary or Backup buses using “fake” SHBOUT6
message which is normally used for signal sharing among the controllers. See jumper description
further in the text.
- Intercontroller CAN bus extension – each I-CR-R module provides also CAN bus extension in the
same way as I-CR module, i.e. creates segments of the bus where the length of the line is limited
within the segment only, not within the whole system.
Note 1: The redundancy system only makes sense if the cables of Primary and Backup buses are
placed physically into different cable routes! Placing them into the same cable route increases the risk
of damage of both cables at once.
Note 2: For proper connection of RS485 line, connect the terminals TxA and RxA together and
terminals TxB and RxB together. This should be done on each I-CR-R module and with short wire
(see drawing).
I-CR-R configuration jumpers:
P3 – Forces 8C (50 kbps) mode on Primary intercontroller bus (name at the original sticker CAN
EMS); if not active, 32C (250 kbps) mode is automatically used.
Note: All I-CR-R modules within the system must be switched to the same mode, otherwise the
primary intercontroller CAN bus won’t work.
P4 – Enables transmission of SHBOUT6 message to local CAN bus; the message is intended to
transmit indication and error flags from the module to the controllers to make the status of the module
visible to the customers. By sending this message, I-CR-R is “cheating” the controllers in it’s local

CAN bus because it is pretending to be one of the other controllers (from intercontroller bus) sending
this message. Do not use the real source for SHBOUT6 message if this feature is enabled.
Contents of the SHBOUT6 message:
Note 1: Typically, configure a Warning-type protection on the lowest bit signal of this message. The
signal becomes active if part of controllers normally “visible” through the Primary or Backup bus is not
visible anymore; this means the cable was cut or shorted or otherwise damaged and doesn’t connect
anymore some part or all the controllers.
Note 2: Because bit 1 activates with the difference between Primary and Backup buses it is able to
indicate failures of both Primary and Backup buses, so even if Primary bus works fine, it is able to
show the problem with Backup bus to allow the technician to repair it before it actually becomes a
problem. Otherwise the problem with the Backup bus would stay hidden until Primary bus would have
failed and then the intercontroller communication would stop working completely.

RS232 cable
It is recommended to use standard Null-modem cable for local connection between controller and PC,
although the three wires (TxD, RxD, GND) RS 232 connection is enough for direct controller to PC
communication:
To use USB connection it is necessary to install drivers on your PC.
The drivers can be downloaded from the website http://www.ftdichip.com/Drivers/VCP.htm.
Download the driver for your operating system and follow the enclosed instructions.
After successful installation of the driver and connection of the controller or I-LB+ to the PC the new
Virtual Communications Port appears in ComAp PC tools and it is possible to open connection via
USB.
Ethernet cable
It is recommended to use standard UTP or STP cable with connectors RJ 45. Maximal length of cable
is 100 m. For direct connection between Controller and PC is necessary to use cross-wired cable (only
in case that your PC does not have automatic recognizing of direct and cross-wired cable).
The bus has to be terminated by 120 Ohm resistors at both ends.
External units can be connected on the CAN bus line in any order, but keeping line arrangement (no
tails, no star) is necessary.
Standard maximum bus length is 200m for 32C CAN BUS MODE and 900m for 8C CAN BUS MODE
(setpoint in comms setings group)
Shielded cable has to be used, shielding has to be connected to PE on one side (controller side).

In some cases is necessary to use the optical isloation of RS485 line. Some modules has ebmaded
optical isolation some needs aditional equipment to ensure the required separation. The need of
galvanic separation depends on distance between the nodes and surrounding of transmittion line. See

CAN-Ethernet gateway allows you to merge up to four CAN bus branches into one global CAN bus
using Ethernet connection. For detailed information about this option see:
For CAN bus extension is possible to use I-CR module. It allows extension of CAN to more segments
with next 200m adition length. for more information read chapter I-CR Module for CAN bus extension.
RS485 connection
External units can be connected on the RS485 line in any order, but keeping line arrangement (no
tails, no star) is necessary.
Standard maximum line length is 1000m.
Shielded cable has to be used, shielding has to be connected to PE on one side (controller side).
RS485 and CAN bus line has to be terminated by 120 ohm resistors on the both ends. Always check
the number and placement of terminating resistors in the CAN bus line, only correct wiring ensures
reliable operation! Resistors must be placed at either end of the line (see picture), and correct number
of resistors must be used! Correct number can be checked using ohmmeter - when power supply for
ALL devices on the CAN bus line is switched off, the resistance measured between A and B wire
should be 60 Ohms. For longer distances is recommended to connect CAN COM terminals between
all controllers and cable shielding to the ground in one point. External units can be connected on the
CAN bus line in any order, but line arrangement (no tails no star) is necessary.

Termination Resistors:
Because each differential pair of wires is a transmission line, you must properly terminate the line to
prevent reflections. A common method of terminating a two-wire multidrop RS-485 network is to install
terminating resistors at each end of the multidrop network. If you daisy-chained multiple instruments
together, you need a terminating resistor at only the first and last instruments. The terminating resistor
should match the characteristic impedance of the transmission line (typically 100–120 Ohms).
Bias Resistors:
The transmission line into the RS-485 port enters an indeterminate state when it is not being
transmitted to. This indeterminate state can cause the receivers to receive invalid data bits from the
noise picked up on the cable. To prevent these data bits, you should force the transmission line into a
known state. By installing two 620 Ohm bias resistors at one node on the transmission line, you can
create a voltage divider that forces the voltage between the differential pair to be less than 200 milliVolts, the threshold for the receiver. You should install these resistors on only one node. The figure
below shows a transmission line using bias resistors. Bias resistors are placed directly on the PCB of
controller. Use jumpers PULL UP / PULL DOWN to connect the bias resistors.
The controller has to be connected to modem via standard modem cable where the DSR (Data Send
Ready) signal detects modem presence (ComAp order code AT-LINK CABL).
Hint:
It is recommended to use the same type of modem on the both sides (and PC) of connection.
For GSM modem proper set-up use automatic ComAp GSM set-up software from the installation
package. Setup software runs independently. In MS Windows select: Start - Program files – Comap –

IG/IS-NT controllers provide a possibility to select whether a modem with active DSR signal (full
modem cable connection - RXD, TXD, GND, RTS, CTS, DSR and DCD control signals available) or
without this signal (3 wire connection – RxD, TxD and GND signals available) is connected.
In the controller the selection is done by Comms settings:RS232(1/2) mode setpoint.
Select MODEM (HW) for full cable connection or MODEM (SW) for 3 wire connection.
Place I-LB jumper “HW/SW control” when MODEM (SW) connection is selected.
Hint:
Make sure all signals are connected and activated in modem when it is not possible to open
connection.
Some types of GSM module have jumpers select table control and handshaking signals.
TC35 Alphatech GSM modem: the first jumper from the left is closed.
GSM Modem setup
Prior to start work with GSM modem run following program for GSM proper setup.
Program writes all the necessary AT commands to configure the GSM modem properly for use with
IG-CU or IS-CU.
This program runs independent on other PC SW:
Start MS Windows-Start-Program files – Comap – Tools – Gm_setup.exe.
Select COM port
Tick when GSM will be used with old iG-MU unit
Press Setup button
Follow commands in GSM Modem Setup window
Selection “Modem will be used with old version of IG-MU (below 1.8)” sets GSM modem Baud rate to
38400 bps !!!
It is strongly recommended to use the same type of modem at both sides (IG and PC) of connection.
When modem TC35i does not respond for sending command SMSes, do the following:
1. Send AT+CPMS="MT","MT","MT" command via
hyperterminal
or by means of RS232()MdmIni parameter.
2. Send AT+CPMS="SM","SM","SM" command via
hyperterminal
or by means of RS232()MdmIni parameter.
3. Restart the modem.
Mobile Phone SIM Card Setting
Adjust SIM card on GSM modem in the following way:
Enable data communication (it could be done by your local GSM operator),
Set phone number SMS service center SC (recommended in international format in case of
roaming),
Set no PIN code required.
Hint:
All SMS on SIM card will be erased during GSM modem initialization. Valid SMS on SIM card will be
served. Except of adjusting and gen-set control command.
Both SIM cards must have DATA services enabled when communicating from controller to PC via two
GSM modems. The GSM tariff should have CSD (Circuit Switch Data) service enabled.
How to check SIM card DATA setting
Move SIM card from controller GSM modem to Mobile phone.
Call from InteliMonitor to this Mobile phone and check (on Mobil phone) DATA call
indication of incoming call.
If phone does not indicate DATA - solve this with your GSM operator.
The functionality of 3G modems with Comap controllers depends on the operator and his network
settings. Therefore it is recommended to first test the controller with such modem.

Converter Modbus RTU Profibus
GE Digital Energy - P485 Modbus to Profibus Converter
For connection of 1-32 NT line controllers to a Profibus network
RS485 or RS232 physical layer for connection to the controller(s)
Full Profibus-DP slave functionality according IEC61158
244 bytes input data size (122 Modbus registers)
244 bytes output data size (122 Modbus registers)
416 bytes total
See deatils on the web page of the manufacturer:
To configure the converter in the Profibus network, download the description file
http://www.geindustrial.com/products/software/d485/P48509E5.zip and import it to the
Profibus configuration tool.
Follow instructions in the P485 manual while configuring the converter. The setup wizard
incorporated in the Enervista software will make the setup process much easier, but finally some
manual corrections are needed. Below are some notes specific to the connection with ComAp
controllers.
1. The physical layer for Modbus communication is select table. The selected type
(RS232/RS485) and speed must be same in the P485 and controller, see Controller
settings.
2. Use RS485 in case more controllers are connected to the P485.
3. A Device mentioned in the wizard represents a controller type (IG-NT, IM-NT, IS-NT).
Once a device is defined, more nodes of the same type (device) can be created easily.
4. A modbus network node represents a controller. The slave address must correspond to
the Controller address setpoint of the related controller.
5. See Modbus Connection chapter in this document for details about Modbus, register
numbers, sizes etc.
6. Use triggered update mode for writing objects (registers) to the controller. Never
use cyclic update mode!
11. For each write-type parameter modify the property Update mode to triggered mode and define
trigger byte address. The Profibus master must update the parameter data field first and then
increase the trigger byte value to write the parameter (register) to the controller.
12. Write the configuration to the P485 and save it also to disk as backup.
