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+.
Controller setup
(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.
INTERNET GATEWAY CONFIGURATION EXAMPLE (PORT FORWARDING)
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.
Equipment
RS232/485 connection (I-LB+)
Hint:
I-LB+ module enables monitoring and configuration up to 32 controllers interconnected via CAN(2)
intercontroller bus. It is also possible to use I-LB+ for single controller connection.
Selection of CAN address. Open = ADDR1, Close = ADDR2
It is possible to use up to two I-LB+ devices in direct mode on CAN(2)
bus. Let jumper open in case of using one I-LB+ module. Other I-LB
module has to have this jumper closed. (read more about I-LB+ module)

Up to 32 controllers can be monitored via one IB-NT (IG-IB). Response time of a system with this type
of connection depends on number of controllers, higher number of controllers means slower system
response time.
Controllers
NOTE:
Max. 3 clients of ComAp type (InteliDDE server, WinScope, WebSupervisor) can be connected
simultaneously to the IB-NT (IG-IB).
Hint:
Get more information about IG-IB internet bridge. For more information about IB-NT internet bridge
read IB-NT-2.0-Reference Guide.pdf.
Ethernet connection is available for all mentioned controllers via external internet bridge IG-IB or IBNT (see the chapter Ethernet connection IG-IB/IB-NT).
Number of clients connected simultaneously
2 clients with InteliMonitor or WebSupervisor (Comap/TCP protocol)
2 clients with web interface
Ethernet connection settings
Perform the connection settings the same way as for Single controller Ethernet connection.
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.
