In this example, set four event inputs are used, the multi-SP function to
“2”, and event input 3 to “Run/Stop” and event input 4 to “Auto/
Manual”. Set as follows:
(1) Set “multi-SP function” parameter to “2”
(2) Set “event input assignment 3” parameter to “
”
(3) Set “event input assignment 4” parameter to “
”

Set points 0 to 3 are set as the set point according to event input. How-
ever, note that these parameters can not be set when the multi-SP func-
tion is not selected. The following table shows the relationship between
event inputs and set points 0 to 3.

* When using 2 event inputs, the multi-SP function is assigned to event
inputs 3 and 4.

When you have changed the set point in the PV/SP display, the set point
of the currently selected is also simultaneously changed.
·
When you have switched between set point 0 to 3, the SP ramp function
works if the SP ramp function is enabled. The following example shows
how the set point changes when you switch from set point 0 to set point 1.
