Description
24 Product Specification S4Cplus M2000/BaseWare OS 4.0
- Program controlled enabling/disabling of I/O units.
- Scaling of analog signals.
- Filtering.
- Polarity definition.
- Pulsing.
- TCP-proportional analog signal.
- Programmable delays.
- Simulated I/O (for forming cross connections or logical conditions without need
the for physical hardware).
- Accurate coordination with motion.
Signals can be assigned to special system functions, such as program start, so as to be
able to control the robot from an external panel or PLC.
The robot can function as a PLC by monitoring and controlling I/O signals:
- I/O instructions are 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 for some robots also be routed parallel or serial to connectors on the
upper arm of the robot.
Types of connection
The following types of connection are available:
- “Screw terminals” on the I/O units
- Industrial connectors on cabinet wall
- Distributed I/O-connections inside or on cabinet wall
For more detailed information, see Chapter 2, Specification of Variants and Options.
ABB I/O units (node types)
Several I/O units can be used. The following table shows the maximum number of
physical signals that can be used on each unit. Data rate is fixed at 500 Kbit/s.
