Locating Mode Parameters

In the Resource and Transducer blocks, the mode
parameters are normally found in the Process
menu. In all other Function blocks, they are found
in the Common Config. menu. The Mode
parameters will also be included in the All
parameter list; see "Working with Device Blocks"
on page 4-13.

Changing Modes

A warning message may appear whenever the
mode of any block is included in a list of parameter
changes to be sent to a device. Press YES to send
the change, or NO to not send the change.
To change the operating mode, set the
MODE_BLK.TARGET to the desired mode. After a
short delay, the parameter
MODE_BLOCK.ACTUAL should reflect the mode
change if the block is operating properly.

Permitted Modes

It is possible to prevent unauthorized changes to
the operating mode of a block. To do this,
configure MODE_BLOCK.PERMITTED to allow
only the desired operating modes. It is
recommended to always select OOS as one of the
permitted modes.
