4-18 Application Examples
You have successfully configured a rack connection to the remote chassis to
communicate with the two discrete and one analog I/O modules. At this point
you may also configure the state of the outputs in the remote ControlNet
chassis when the processor is placed into the Program mode or if
communications are lost to the remote chassis. This is optional. The default is
to turn all outputs off when one of the two conditions occur. To select other
options, click on the Advanced tab in the Connection Properties window. The
following window will appear:
By default, outputs in all slots in the remote chassis are reset if the processor is
placed into the Program mode or if communications are lost for any reason.
Two other choices are offered when one of the two conditions occur. They are:
•
Hold Last Outputs
•
Outputs to Safe State
Hold Last Outputs holds outputs in their last state if one of the two conditions
occur. Safe State allows you to choose the exact state of each output. If Safe
State is selected, you must click on the Configuration Settings tab and enter your
Safe State data for each output word in decimal. Then, if the SLC processor is
placed in the Program mode or if communications are lost to the ACN15
adapter, the outputs revert to the Safe State data you entered for each output
word.
Click Apply, then OK to return to the ScanList Configuration screen.
