Network Settings
Each PROFINET IO Controller and Device needs to have a PROFINET name and IP address to
communicate on the PROFINET network. The settings of the name and the IP-Address are done in
the Network Settings area. The characters in the name must be lower case and can include num-
bers and the “-” sign. This is according to the PROFINET specification. Incorrect characters are not
accepted.
The IP-address and the Subnet Mask must conform to the IP network the PROFINET IO Controller
will be working in. Gateways, however are not supported.
Auto-Addressing
Auto-Addressing defines whether or not the CJ1W-PNT21 IO Controller DTM will automatically map
the I/O data in such a way that no gaps exist in the I/O data. If enabled, the user does not need to
manage the exact mapping of I/O data to the CPU memory areas.
Valid Output Data Handling
Depending on the application, set the Valid Output Data Handling to PLC Mode Dependent or User
Bit Controlled. If set to PLC Mode Dependent, the IO Controller will follow the state of the CPU (Pro-
gram or Run mode). This is convenient in most applications where only one IO Controller is used. In
systems where the application needs to be in control of the state of the output data, select User Bit
Controlled.
An example to use User Bit Controlled is a redundant configuration where two IO Controllers can
control IO Devices but only one is Active and the other is the Standby. The Active will set the Output
Data to Valid and the Standby has Invalid Output Data. The IO Device will only use the Output Data
of the IO Controller that has set it to Valid.
After making the changes, select the
Apply
button in the lower right corner of the user interface to
accept the changes. Next select the IO Device Setup to set the information for the IO Devices.
In the IO Device Setup, the Names of the IO Devices that the IO Controller will search for (to connect)
are set. Also, other settings like IP-address, Update rate, Watchdog and Datahold-time need to be set
here.
Device No.
The Device No. is assigned by the IO Controller DTM and is used in several places.
The functions where the Device No is used are:
•
In the Connection and Diagnostics information screen of the IO Controller.
