Configurable automation controller (CAC)

The iMod presents an innovative approach to telemetry and automated systems

The iMod is a configurable protocol controller, guaranteeing fast start-up and full exploitation of device capabilities without the need for writing programs. A fully configurable system reflecting typical C-L-V use.? Realizes the functions of devices such as:

Thanks to universal and elastic architecture and plug-in type solutions, it can fulfill the role of a universal communications modules servicing any user-made protocols

Distinguising features

• Full MODBUS service?? a Modbus proxy/gateway/router, many Slave and Master channels, buffering of temporary values

• Alarm functions?- information on events through text messages, e-mail, SNMP, Modbus, PUSH, SQL, and user scripts

  

• Datalogger?? recording of data is only limited by FLASH memory (1 GB) or SD card size

• WWW Access?? a standard installed PHP template with SQL service, and the optionally available NX Dynamics platform for fast creation of control and visualization charts

Operation principle

The iMod platform has been designed do as to take into consideration all methods of communication used by modern automated and telecommunications systems, while maintaining clarity and elasticity of the configuration. For this purpose, 3 types of communications channels have been defined.

• Source channel??- a channel for cyclic downloading of appropriately defined parameter values (e.g. Modbus Master queries other devices)

• Access channel?? a channel giving access to iMod data (e.g. Modbus Slave gives access to data for a SCADA computer)

• Message channel?? communication based on events enabling notification e.g. in the form of text messages, email, or Modbus Push messages

Additional components

• iMod?SDK?makes it possible to add your own protocols using a "plug-in" system

• The iMod operates on the?NPE Linux?platform, which ensures a rich set of programming tools, servicing of the C, C++, and Java languages as well as tools for servicing of databases such as SSH, SSL, and VPN

• NX Dynamics (optional)?- allows for access to iMod data from a WWW browser and for construction of impressive visualization charts in a fast and easy way, does not require familiarity with HTML or PHP

• NPE PLC (optional) -?makes it possible to execute PLC ladder algorithms directly using iMod data/parameters
