Motion Controller Functions 627
The RIO_output function is evaluated as 1 (true) if the output is ON and 0
(false) if it is OFF.
RIO Scanner Output
Use the RIO_scanner_output function to directly specify the RIO
scanner outputs, on Integrated and Basic motion controllers, in an
expression.
You define and select RIO scanner outputs using the Tag Explorer (under
RIO Scanner Output) and Tag Window. It is not necessary to use this
function to specify them directly.
Syntax:
RIO_scanner_output[group, address]
The RIO_scanner_output function is evaluated as 1 (true) if the output is
ON and 0 (false) if it is OFF.
SLC Bit Output
Use the SLC_bit_output function to directly specify the SLC bit outputs
in an expression. This function is available only on 1394T motion
controllers.
You define and select SLC bit outputs using the Tag Explorer (under SLC
Output Bit) and Tag Window. It is not necessary to use this function to
specify them directly.
Syntax:
SLC_bit_output[address]
Argument Description
Group The starting group of the output (from 0 to 7) to be sent.
Address The address or signal number (from 0 to 15) of the first signal from which
output is sent.
