How to configure a velocity routing in the Flexi Soft Designer:
⋅
Configure the velocity routing in the Flexi Soft Designer for instance as in the following
figure.
Input signals from the
S300 Expert with
incremental encoders
Output signals to all
safety laser scanners
EFI string 1 (safety
laser scanner on
EFI1.1
0
and
EFI1.2
4
)
12 + 1 bit pattern
duplicated and placed
on the n:n function
blocks EFI1.1
0
EFI string 2 (safety
laser scanner on
EFI2.1
5
and
EFI2.2
2
)
The velocity signals of the S300 Expert are broken down into a 12 + 1 bit pattern, 12
velocity bits and one bit for validation. These signals are available as input signals, are
duplicated and placed
twice
on the n:n function blocks (0 and 1 as well as 2 and 3).
The outputs of the function blocks are placed on EFI string 1 or on EFI string 2. As a result
they are available to all four safety laser scanners.
WARNING
The “Velocity valid” status information is relevant for safety!
Ensure that the
Velocity valid
input signal is connected to the
Velocity valid
output signal.
How to configure the safety laser scanners in the CDS:
⋅
On the
Incremental encoder
tab for the S300 Expert to which the incremental encoders
are connected, select the
Indicate velocity
option.
All safety laser scanners, also the sending devices, must use these velocity signals via EFI.
⋅
For this reason activate
on all
safety laser scanners on the
Inputs
tab the option
Use
Flexi Soft CPU1/2
.
⋅
Then, select
on all
safety laser scanners on the
Inputs
tab the
Use velocity
option.
