Motion Controller Functions 621

In our example, to create a bit mask for the group beginning at bit #2 and

ending at bit #5, but excluding bit #3, add together these binary values:

The first input in your group (unless it is masked) has the binary value of

1, no matter what its address number may be.

RIO Group Input

Use the RIO_group_input function to directly specify RIO adapter input

groups in an expression.

You define and select input groups using the Tag Explorer (under RIO

Adapter Input Group) and Tag Window. It is not necessary to use this

function to specify them directly.

RIO_group_input[address, total signals in group, optional mask]

Bit Number / Status Binary Value

2 / ON 1 (the first bit in the group)

3 / OFF 0 (masked)

4 / ON 4 (the third bit in the group)

5 / ON 8 (the fourth bit in the group)

Bit Mask = 13

Argument Description

Address The address or signal number (from 0 to 11) of the first signal whose

output is read.

For this bit

in an input group Use this Binary Value
