Chapter 2 Outline - Hitachi WJ200 Series Quick Reference Manual

2.1 Outline of product
WJ-PN is an interface option of PROFINET communication for WJ200 / WL200. WJ-PN allows
controlling, monitoring and parameterization of WJ200 / WL200 via the PROFINET network.
PROFINET is an open, digital communication system. PROFINET is anchored in the international
standards IEC 61158 and IEC 61784.
WJ-PN supports the application profile PROFIdrive version 4.2. This profile defines device behavior
and the access procedure to drive data for electric drives on PROFINET or PROFINET.
(1) PROFINET
WJ-PN supports PROFINET IO Ver.2.32.
The conformance class of WJ-PN is B.
(2) Cyclic communication
The PROFINET IO controller manages the PROFINET network, and performs PROFINET IO device
status monitoring and data exchange with the PROFINET IO devices.
The format of communication data conforms to PROFIdrive.
Output data (to PROFINET IO device)
Input data (to PROFINET IO controller) : operation status, present value, etc.
(3) Setting the inverter parameters
You can set the inverter parameters by using acyclic communication of the PROFINET.
The procedure to access parameters conforms to PROFIdrive.
: operation command, target value, etc.
