Programming Function Blocks and Features

Advanced Splitter Output (ADV SPLITTER)

This function can be used for heat/cool applications. It splits an input into 3 independently scaled outputs: CVn_A1, CVn_A2 and CVn_A3 (Figure 4-12). For each output, when the input is between IN LO LIM and IN HI LIM, the output is scaled between the OUT LO LIM and OUT HI LIM. Each output holds its OUT LO LIM value when the input < the IN LO LIM value for that output. Each output holds its OUT HI LIM value when the input > the IN HI LIM value for that output. Output limits (OUT LO LIM & OUT HI LIM) cannot exceed 100% but can be negatively sloped (OUT HI LIM < OUT LO LIM).
