Internal Parameters
Function Transfer a value from one control icon to other icons or points.
Copies the input to all outputs.
Input One input, required. Any input point type or control icon can be an input.
Output One to five outputs (Excel Web / Excel Web II: one to 32 outputs), one required.
Outputs can connect to any output point (analog or digital, physical or pseudo) or to
the input of other control icons (except another IDT). An IDT cannot be an input to
another IDT.
The first output type determines all other output types. For example, if the first
output connects to an analog point, all other outputs must connect to an analog
point (Not for Excel Web / Excel Web II).
If the input and output types are mismatched, IDT converts the input signal to the
appropriate output signal. For example, if the input is an analog point and one of the
outputs is a digital point, IDT converts the analog signal to the proper digital signal.
