Intelligent Controller for DeviceNet Network

 

With the use of the I-7242D external module, the NPE/iMod industrial computer is perfect for control and management of the objects in the DeviceNet networks. The communication between the module and the computer is carried out through the Modbus RTU protocol. Next, all the data can be transferred to a local HMI or using the GPRS - to a control station.

Networks using the DeviceNet protocol are widely used in communications between a PLC and the I/O devices. An unquestionable advantage is that it can be powered directly with a data transmission cable and the fact that it is an open standard. This network enables connection up to 64 devices, the cable length can reach up to 500 metres.


Networks using the DeviceNet protocol are comprised of such devices as:

  • switches,
  • sensors,
  • controllers,
  • HMI,
  • input interfaces,
  • valves.

The DeviceNet networks are mainly used in Industrial Automation. The main features are easy installation, high efficiency and minimum number of cables. The use of the NPE/iMod computer enables transfer of collected data through the GPRS network – it reduces the number cables used for installation. This solution is all the more beneficial since you can get access to data from the control panels hundreds of kilometres away.

The communication between the telemetric module and the converter is carried out through the RS-485 interface and the modbus protocol. The I-7242D module works as a Gateway – it connects DeviceNet slaves to Modbus RTU masters. The converter is fully transparent, which means that all the data from controlled objects are sent directly to NPE/iMod.
