Access Path
Use of this field is optional.
Use the access path field in the Node editor when:
you want to be able to switch between PLCs using the
NodeSwitch command for node redundancy
you want all tags in RSView32 to have the same update rate
You must leave the access path blank if you want to use different
update rates for different tags in the tag database. If you leave the
access path blank in the Node editor, specify the access path in the
Tag Database editor’s tag address field.
For information about the syntax for the access path, see your
OPC server documentation.
If you use this field, and you are communicating with RSView32
using OPC, the access path is the name of the current project on
the server.
If you use this field, and you are communicating with an RSLinx
OPC server, the access path is the name of a DDE/OPC topic on
the server. If you leave the access path blank, you must specify the
DDE/OPC topic as part of the tag’s address when you create the
tag using the Tag Database editor.
Update Rate
Specify the fastest rate at which the OPC server sends data to the
OPC client. The default is every 1 second.
The rate that the OPC server uses may be slower than the rate you
specify. Type 0 to specify that the server use the fastest possible
rate.
If the OPC server’s access path is a DDE/OPC topic, the update
rate should not be faster than the topic poll rate.
