When adding a CJ1W-PNT21 IO Controller DTM to the network, it is automatically assigned
the IP address 192.168.0.100. This address can be changed, after opening the CJ1W-PNT21
IO Controller DTM. After adding the Master DTM to the Network view, repeat (one of) the pro-
cedures as outlined above to add slave DTMs to the Master DTM. In the procedures above,
the highest level for adding slave DTMs is the Master DTM. When adding IO Device DTMs to
the CJ1W-PNT21 IO Controller DTM, they are automatically assigned their Device Number
and TCP/IP network addresses, in ascending order, i.e. the first IO Device is assigned the
Device Number 1 and IP address 192.168.0.1, the second gets the Device Number 2 and IP
address 192.168.0.2, etc. The assignments can be later changed in the IO Controller DTM
User Interface.
The PROFINET IO addressing is based on IO Device Naming. In order to achieve communication
between the IO Controller Unit and its allocated IO Devices, the latter must have the same PROFI-
NET Name set in the configuration as it is set in the IO Device. The PROFINET Name on the IO
Devices is set by a specific tool. There are standalone tools but there is also on incorporated in the
CJ1W-PNT21 PROFINET IO Controller DTM. When opening the IO Controller DTM the first item
show is the PROFINET identification with the Network Scan sub item.
See the picture below:
Searching Devices
Pressing the
Search Device
button will let the PC search the connected Ethernet networks for
PROFINET IO Devices. Therefore the PC must have an Ethernet connection to the PROFINET net-
work.
All PROFINET IO Controllers and IO Devices found will be shown with their:
•
MAC Address, which is fixed internally by the vendor during production, makes it unique in the
Ethernet network.
•
Device Type, is fixed by the Vendor and is often just the product name
•
Device Name, is set by the user and is fixed in the device. This name is used by the IO Controller
to find the IO Device before setting up connections.
•
IP Address the device currently holds. It could be temporary or fixed. For an IO Device it will be
overwritten by a value set in the configuration of the IO Controller.
•
Protocol that is used to find the device.
Configuring Devices
The
Configure
button will display four other selections that can be performed on the selected PRO-
FINET IO Controller or Device:
