12-4 Protecting Your Programs
For example, set your privilege classes as follows on the channel privileges
screen of your programming software (an X indicates that the privilege is
enabled):
Assigning a Privilege Class
to a Channel or Offline File You can assign a privilege class to all channels (except remote I/O scanner or
adapter channels) and offline files. Each channel and offline file has a Class 1
privilege by default.
The read/write privileges you see on the channel privileges screen apply to
read/write access to the channel configuration screen of that channel. The
read/write privileges for each channel’s diagnostic file (channel status screen)
must be set up through the data table privileges screen. The default privilege
fields on the channel privileges screen determine the privilege class of all
stations/nodes that are attached through that channel.
Assigning a Privilege Class
to a Node All stations/nodes default to the same privilege class as that of the channel
they communicate through. You can give a node its own privilege class if you
want it to have a class different from the default privilege assigned to that
channel.
