4. Select Transfer to PLC from the Options menu to transfer the network parameters to the
unit.
5. Select the Reset Unit setting to restart the unit - the written settings are activated in the unit.
Note:
If the unit which is being set is the one on which the current communication to the PLC
is being made, the PLC needs to be closed and opened before communications can
continue.
Ethernet
The Ethernet setup differs from SYSMAC LINK, SYSMAC NET and Controller Link by not having a Data Link
Area setup and by having two further dialog boxes, the IP Address Table and IP Router Table. This particular
interface requires that each device attached to the network has an IP address, and that routing information for
directing data across the network is also included (where necessary); such address information ensures that data is
transmitted correctly between two nodes.
Note:
Table information is only used if the IP Address Conv. Method radio button is not set to
Auto .
The File Transfer Protocol (FTP) allows access to a file card on the PLC. If a FTP login name and password are
entered then these are used to start an FTP session. For more information, refer to the Ethernet User’s Manual.
The IP Address Table dialog allows the IP address of a network node to be entered.
1, 2, 3… 1. Select the Ethernet Unit from the IO Table and click the right-mouse button.
2. Select the Unit Setup option.
3. Click on the Insert pushbutton.
4. Enter the IP Address for the node in the IP Address field; each of the four fields must take
a value in the range 0 to 255.
5. Select the OK pushbutton to proceed.
6. Click on the Delete pushbutton to remove the address from the table.
7. Select Transfer from PLC from the Options menu to write the changes back to the table.
The IP Router Table establishes communications between different networks by maintaining the IP address for
each interface and is created by clicking on the
Insert pushbutton above the IP Router table dialog. Procedures are
the same as for the IP Address Table described above.
Syslink Unit and Controller Link Specific Settings
A Syslink unit Software Switches dialog includes a General tab and Data Link tab described previously.
The Error Information tab provides read-only information regarding the errors that the PLC can detect and raise
an error flag.
The Network Status tab provides network status information. It also activates the PLC to perform internode tests.
Select the Start option to set the PLC to check for errors and report them. Select the Stop option to stop the PLC
from detecting errors. The Network Node List field lists the network nodes and whether they are participating in
the network operations.
Sysmac-Bus2 Unit Specific Settings
A Sysmac-Bus2 unit Software Switches dialog includes a General tab described previously.
The Slave tab provides specific status information to the Sysmac-Bus2 unit. There are various types of slave that
may be connected to a Remote IO Master unit. These slaves include IO Terminals, Programmable Displays and
Remote IO Slave units.
To view the slaves connected for a group, select the Group required from the field at the top of the Slaves tab. The
remainder of the Slaves tab displays the Node and Status for each category.
If the hierarchy of the IO Table has been expanded, the three groups can be populated with other units:
♦
Group 1. 16-point and 32-point IO units.
♦
Group 2. 16-point, 32-point, 64-point and 128-point IO units and 256-point dummy.
♦
Group 3. 58M Remote Terminal, 54MH Remote Terminal and 122M Remote Terminal.
