You have successfully configured a rack connection to the remote chassis to
communicate with the two discrete 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 appears:
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 Output 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 you
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 ACN adapter,
the outputs revert to the Safe State data you entered for each output word.
