IGS-NT Communication Guide 03-2014.pdf
Scope of the document
There are following types of communication between controller(s) and superior system in the
controller.
1. Local (on site) communication
via ComAp software
via MOUDBUS (MODBUS RTU or MODBUS TCP)
2. Remote communication
via Ethernet
via Internet (AirGate)
via MODEM
These types of connections are available via RS232, RS485, USB, ETHERNET
communication ports.

IGS-NT Communication Guide 03-2014.pdf
Definition of terms
Local connection
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.
