Enabled

Normally nodes are enabled, allowing collection of values from the
programmable controller. However, during setup or
troubleshooting you might want to disable a node to prevent
communication timeouts or invalid data. When a node is disabled,
tag values can still be read and written, but the values are read from
and written to the value table instead of the programmable
controller.

When a tag uses a disabled node at runtime, the tag’s state will
change from valid to disabled. A tag’s state can be seen by viewing
the tag in the tag monitor.

To disable nodes, clear the Enabled check box.

You can also enable and disable nodes at runtime, using the
NodeEnable and NodeDisable commands. For more information
see Appendix A, RSView32 commands.

Channel

Select the channel number on which this node resides.

Station

Type the station address of the programmable controller. For
addressing syntax, see Appendix E, Station addressing for nodes
connecting to Allen–Bradley devices
.

If RSLinx 2.0 or later is installed and running on your computer,
click the ... button next to the Station field to open the RSWho
window that displays all active PLC stations for the selected
channel. When you select a station from the RSWho window, the
Station and Type fields are filled in automatically. RSView32
substitutes PLC-5 (Enhanced) for all PLC-5 series device types.
Change the entry in the Type field to PLC-5 if you are using the
PLC-5/10, 5/12, 5/15, or 5/25.
