FINS Routing
The CJ1W-PNT21 PROFINET IO Controller not only supports PROFINET IO
Communication but also the Omron FINS communication to transfer FINS
commands.
FINS commands are message service communications commands. They do
not depend on a particular transmission path. They can be used for
communications on various networks (Controller Link, Ethernet, etc.) and for
serial communications (Host Link). They can be issued from a CPU Unit,
Special I/O Unit, or host computer, and they can also be sent to any of these.
The specific commands that can be sent depend on the destination. For more
information refer to
Communications Commands Reference Manual (W342)
The FINS communication supported by the CJ1W-PNT21 PROFINET IO
Controller is UDP/IP. Also know as the FINS/UDP or the Ethernet connection.
Over this FINS/UDP connection for example a HMI terminal can communicate
to the PLC to read and write PLC memory.
Also from the PLC program FINS commands can be sent with the CMND
command to other PLC’s or devices on the network.
An example are the parameters in the SmartSlice Units connected to a GRT1-
PNT SmartSlice PROFINET IO Device. The command code to get or set
parameters is 2801. For more information refer to
GRT1-PNT PROFINET IO
Communication Unit (W13)
The CJ1W-PNT21 uses the following rules for the FINS-address to IP-address
translation when routing FINS commands onto the Ethernet network.
IO Device Number
• The FINS-address is compared to the IO Device numbers configured for
the IO Controller. Each IO Device number corresponds to an IP-address.
