Installing and Configuring Your ControlNet PLC-5 Backup System 3-7
Configure ControlNet I/O on the Second PLC-5
Configure all ControlNet I/O adapters and modules that will be in
your backup system, and ensure that the ControlNet I/O mapping and
data file assignments on the second PLC-5 match those on the first
PLC-5.
1. From the Scanlist Configuration screen (for the second
PLC-5), right click on the node corresponding to your I/O
adapter and choose Auto Insert > Selected Devices.
If you are not currently in Edit mode, you are prompted to
switch to Edit mode.
2. Click yes.
3. At the bottom of the Scanlist Configuration screen, enter data
table file addresses and sizes in the Diagnostic File,
Configuration File, Data Input File, and Data Output File
fields.
4. Select each adapter and module in the backup system and enter
the data table address that matches the address assigned on the
first PLC-5.
5. From the File menu, choose Save to save the completed
ControlNet configuration.
IMPORTANT
RSNetWorx for ControlNet does not automatically
assign the same data file addresses for redundant
connections on different PLC-5 programmable
controllers. Make sure the data file addresses match
exactly.
IMPORTANT
Note that these addresses and sizes must be
identical for both PLC-5s in your backup system.
Be careful to enter file numbers which do not
conflict with existing data table files.
