If SWAP_2 is set cascade initialization is controlled by the lower block When this block is in OOS mode the cascade to both the lower and upper blocks is broken by Bad status at the outputs When the block goes to AUTO mode the lower block can begin cascade initialization with status values that pass through this block to the upper block The output status signals from the upper block pass through this block to the lower block The block does not use STATUS_OPTS 3 15 Output Splitter block The output splitter block drives two control output signals from a single input signal Each output is a linear function of a fraction of the input signal The same linear function when used in reverse provides the back calculation support For different combinations of input and output conditions a decision table supports cascade initialization This block finds application in split ranging or sequencing of multiple valve In a typical split range application when the splitter input is 50 both the output valves remain closed One of the valves opens proportionately to full as the input drops to 0 and the other valve opens proportionately as the input rises above 50 In a typical sequencing application both the valves are closed at 0 input One of the valves opens proportionately to full as the input rises to 50 while the other stays shut The second valve opens as the input rises above 50 and the first valve may remain open or shut off quick
