Communication - ABB IRB 4400 Manual

The robot can work as a PLC by monitoring and controlling I/O signals:
- I/O instructions can be executed concurrent to the robot motion.
- Inputs can be connected to trap routines. (When such an input is set, the trap
routine starts executing. Following this, normal program execution resumes. In
most cases, this will not have any visible effect on the robot motion, i.e. if a
limited number of instructions are executed in the trap routine.)
- Background programs (for monitoring signals, for example) can be run in
parallel with the actual robot program. Requires Multitasking option, see
Product Specification RobotWare.
Manual functions are available to:
- List all the signal values.
- Create your own list of your most important signals.
- Manually change the status of an output signal.
- Print signal information on a printer.
I/O signals can also be routed to connectors on the upper arm of the robot.

2.11 Communication

The robot can communicate with computers or other equipment via RS232/RS422
serial channels or via Ethernet. However this requires optional software, see Product
Specification RobotWare.
