Mode Description
Out of Service (OOS) The functions performed by the block will not execute. If the block has
any outputs, these will typically not update and the status of any values
passed to other blocks is "BAD". Before you change the configuration of
the block, change the mode of the block to OOS. When the changes are
complete, change the mode back to Auto.
Mode parameters
Mode parameters change the block mode from one state to another. For example, you
may want to change from Auto mode to Out of Service.
In the resource and transducer blocks, the mode parameters are often in the Process
menu. In all other function blocks, the parameters are in the Common Config menu.
