Create User-Defined Function Blocks 8-7

Define I/O Positions

For input and output variables, you need to define the variables’

positions on the function block. The position portion of the variable

declaration display is only available for input and output variables.

You can define:

kg Kilogram mass

lm Lumen illumination

lx Lux illumination density

m Meter length

mol Mol amount of substance

N Newton force

Ohm Ohm electrical resistance

Pa Pascal pressure

Rad Radiant plane angle

s Siemens electrical conductance

S Second time

sr sRadiant solid angle

T Tesla magnetic flux density

V Volt electrical potential

W Watt power

Wb Weber magnetic flux

Abbreviation Unit Definition

In this field Define

Connection the side of the block (left, top, right, or bottom) to which the input or output should be connected

Position the position of the input or output within the block

Inverted whether to invert I/O of data type BOOL

You can only invert BOOL data. Inversions are indicated by a circle around the I/O.

Alternate I/O identifier an I/O-name

This name appears in the block, rather than the generated name.
