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. The characters in the name must be lower case, numbers and the -
sign. This is according to the PROFINET specification. Incorrect characters
are not accepted.
The IP-address and the Subnet Mask must be according the IP-network the
PROFINET IO-Controller must be working in. Gateways, however are not
supported.
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 handle the exact mapping of I/O
data on to the PLC memory areas.
Depending on the application set the Valid Output Data Handling to PLC Mode
Dependent or User Bit Controlled. If set to PLC Mode Dependent then the IO
Controller will follow the state of the PLC, Program or Monitor/Run mode. This
is convenient in most applications, where only one IO Controller is used.
In case where the application needs to be in control of the state of the output
data then set User Bit Controlled.
Example where 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 the IO Controller will
search for to connect to are set. Also other settings like IP-address, Update
rate and Watchdog- and Datahold-time need to be done here.
