RIO Scanner Group Input
Use the RIO_scanner_group_input function to directly specify RIO
scanner input groups in an expression.
You define and select input groups using the Tag Explorer (under RIO
Scanner Input Group) and Tag Window. It is not necessary to use this
function to specify them directly.
Syntax:
RIO_scanner_group_input[group, address, total signals, optional
mask]
SLC Bit Group Input
Use the SLC_bit_group_input function to directly specify SLC bit input
groups in an expression.
Total Signals in Group The total number of consecutive signals (from 0 to 16) comprising
the group, including any masked (or omitted) signals.
Optional Mask An integer representing the sum of the binary value of each group
input bit whose signal is read, excluding—or masking—the binary
value of every group input bit whose signal is not read. (See
Optional
Masks in the Group Input section.)
Argument Description
Group The starting group of the input (from 0 to 15) to be read.
Address The address or signal number (from 0 to 11), of the first signal from
which input is read.
Total Signals The total number of consecutive signals (from 1 to 16) comprising the
group, including any masked (or omitted) signals.
Optional Mask An integer representing the sum of the binary value of each group input
bit whose signal is read, excluding—or masking—the binary value of
every group input bit whose signal is not read. (See
Optional Masks in
the Group Input section.)
