System Functions
The argument is evaluated as an integer (floating-point values are
truncated) and must have a value of 0 or 1. The Axis_output function is
evaluated as 1 (true) if the output is ON and 0 (false) if it is OFF.
RIO Output
Use the
RIO_output function to directly specify RIO adapter outputs in
an expression. This function is available only for Integrated and Basic
motion controllers.
You define and select RIO adapter outputs in the Tag Explorer (under RIO
Adapter Output) and Tag Window. It is not necessary to use this function
to specify them directly.
Syntax:
RIO_output[address]
Insert a value or expression equal to the desired output address. The
argument is evaluated as an integer (floating-point values are truncated)
and must have a value between 0 and 99 inclusive. The available user-
defined RIO adapter outputs are numbered, and correspond to PLC output
bits as shown in the following table:
