Performing Split Computations
[V-mode Output]
The following explains an example of letting “Analog OUTPUT-1 (terminals
16
and
17
)” and
“Analog OUTPUT-3 (terminals
14
and
15
)” present the V-mode characteristics of split
computations.
[1] Set the Control Output Type (OT1) parameter to “2”.
This sets the control output to “current output.”
[2] Set the Retransmission Output 1 (RET1) parameter to “3”.
This sets the retransmission output to “control output retransmission.”
[3] Set the Analog Output-1 100% Segmental Point (A1H) parameter to “100%”.
[4] Set the Analog Output-1 0% Segmental Point (A1L) parameter to “25%”.
[5] Set the Analog Output-3 100% Segmental Point (A3H) parameter to “0%”.
[6] Set the Analog Output-3 0% Segmental Point (A3L) parameter to “75%”.
The figure below shows an example where both analog outputs-1 and 3 are set to the
current signal of 4 to 20 mA DC. The type of output signal can be determined separately for
each of the analog outputs listed above, using the following three parameters.
Analog output-1: Analog output-1 type (AO1)
Analog output-2: Analog output-2 type (AO2)
Analog output-3: Analog output-3 type (AO3)
