3 Software overview
3.1 Information about I/O devices
General
To use the ABB I/O devices, plug-in the base device and the add-on devices to the
controller through the Ethernet cable. Then configure the I/O device by using
RobotStudio or FlexPendant. For more information on configuring the I/O device,
see
Using Discrete I/O devices on page 42
Industrial network
The EtherNet/IP is the industrial network for the I/O devices to communicate with
the robot and the controller.
EDS file
An EDS file is required only when configuring the I/O device with other scanners.
An Electronic Data Sheet file, EDS file, is available for the I/O device to identify the
devices when configured in the network. The EDS file for the I/O device is stored
in the controller and location is:
...\RobotWare\RobotControl_x.x.x-xxx\utility\service\ioconfig\EDS\
Behavior
ABB I/O devices support both
Cyclic
and
Change of State
(COS) I/O connection.
It is possible to set output signals with a Change of State connection.
Note
Change of State is used together with production inhibit timer, which is calculated
as Request Packet Interval (RPI) divided by 4. RPI/4 is the highest frequency for
which a signal change can occur with Change of State.
