5–6 Changing the Network Type
Publication 2711E-6.12 – August 1997
4. Choose Yes to change your Modbus application to DH+. Choose
No if you do not wish to continue with the conversion.
Note: PanelBuilder checks that the station numbers and device types
of all Modbus nodes are valid when the network type is converted to
DH+. For example, station number 8 is an invalid octal number. The
following message will appear, prompting you to convert
incompatible nodes:
5. Select Yes or No.
If you select Yes:
•
the device type of any node will be changed to PLC-5
(Enhanced)
•
an Unsolicited_Msgs node will be added
If you select No, the network conversion will be cancelled.
If you change an application from Modbus to Remote I/O, you will
have to define the necessary Racks, specify the Block Transfer File
and Pass-Through control bytes, if needed, and add new tag
addresses, which are valid for Remote I/O.
To change the network type from Modbus to Remote I/O:
1. Choose Change Network Type from the Tools menu.
2. In the Target Network field, choose Remote I/O.
3. To convert the tags in the application, select the Convert Tags
check box. If you don’t want to convert tags in the application,
clear the check from the Convert Tags check box.
•
If you don’t convert the tags to Remote I/O format, the tags’
data source remains Device and the address is unchanged. You
will have to change the data source to Remote I/O manually
for any of these tags that you want to use, and give them each
a Remote I/O address.
•
If you convert the tags to Remote I/O, the data source for all
the tags is changed to Remote I/O, but you will still have to
give them valid Remote I/O addresses manually.
Note: Converting tags that are shared may make them invalid for
the other applications that are using them. Unused tags that are
not converted will stay as Modbus tags.
