1 General I/O description
General
This description covers all signals in a standard arc welding system based on the
standard process interface delivered by ABB Robotics.
By using the arc welding system configuration add-in, the I/O configuration for the
selected process equipment and options will be installed.
Composition
There are four standard I/O places inside the cabinet.
The system interface is equipped with the following I/O devices as standard:
• Simulated I/O device
• Process interface device
• Digital I/O device
• Software I/O device
Unused I/O device places can be equipped with other I/O devices, as described in
the product specification.
Usage
The number of I/O signals to be used is determined by the welding cell
configuration:
• Welding equipment
• Positioners
• Operator panel
• Cleaning equipment
• Search sensor
• Other options
To minimize the number of I/O devices and signals, a simulated I/O device is used
for some system signals and operator ready signals. The operator ready function
is handled using I/O cross connections with logical conditions.
System configuration
The complete I/O configuration for a specific system setup is obtained during the
boot sequence. After start-up, we recommend creating a backup of the system to
save the system configuration.
Related information
Physical connections of I/O signals are shown in the electrical drawing for the
signal interface (inside the controller cabinet).
I/O devices, CAN-bus connection, and address keying are described in the product
manual for the robot controller.
