Output splitter block
The output splitter (OSPL) function block provides the capability to drive two control
outputs from a single input. It takes the output of one PID or other control block to control
two valves or other actuators.

Function blocks with default block indexes up to 1500 are permanent. Function blocks
with default block addresses 1600 and higher are instantiated and can be deleted.
2.5.2 Modes
The resource, transducer, and all function blocks in the device have modes of operation.
These modes govern the operation of the block. Every block supports both automatic
(AUTO) and out of service (OOS) modes. The blocks may also support other modes.
Changing modes
To change the operating mode, set the MODE_BLK.TARGET to the desired mode. After a
short delay, the parameter MODE_BLK.ACTUAL should reflect the mode change if the
block is operating properly. The automated procedures (methods) make appropriate
resource, transducer, and analog input block mode changes for most configuration tasks.
Permitted modes
You can prevent unauthorized changes to the operating mode of a block. To do this,
configure MODE_BLK.PERMITTED to allow only the desired operating modes. Emerson
recommends always selecting OOS as one of the permitted modes.
