Overview of PROFINET
PROFINET is the innovative and open standard for Industrial Ethernet. PROFINET satisfies all require-
ments for automation technology. With PROFINET, solutions can be implemented for factory and pro-
cess automation, for safety applications and for motion control. PROFINET is now standardized in IEC
61158 and IEC 61784. The use of PROFINET minimizes the cost of installation, engineering and com-
missioning.
As a common solution for industrial communication, the PROFIBUS International Organization intro-
duced the PROFINET Industrial Ethernet standard. PROFINET is the next step for building on the cur-
rent:
•
PROFIBUS DP, the well-known and established fieldbus;
•
Industrial Ethernet.
The CJ1W-PNT21 PROFINET IO Controller is a Unit that can be installed on an NJ-series controller
system. The Unit provides a communication means through a PROFINET IO network to OMRON and
non-OMRON PROFINET IO Devices.
The CJ1W-PNT21 PROFINET IO Controller Unit, a CPU Bus Unit, controls the data exchange between
PROFINET IO Devices (i.e. Smartslice I/O Units) and an NJ-series controller system over a PROFINET
IO network.
The following are features of PROFINET networks and the CJ-series PROFINET IO Controller Unit
(CJ1W-PNT21).
