Description
Product Specification S4Cplus M2000/BaseWare OS 4.0 23
1.13 I/O System
A distributed I/O system is used, based on the fieldbus standard CAN/DeviceNet. This
makes it possible to mount the I/O units either inside the cabinet or outside the cabinet
with a cable connecting the I/O unit to the cabinet.
Two independent CAN/DeviceNet buses allow various conditions of I/O handling.
Both channels can be operating as master or slave. One bus, CAN1, is operating with
fixed data rate, and the other, CAN2 (accessible by the software option I/O Plus), with
different data rates.
Figure 11 Example of a general DeviceNet bus.
A number of different input and output units can be installed:
- Digital inputs and outputs.
- Analog inputs and outputs.
- Gateway (slave) for Allen-Bradley Remote I/O.
- Gateway (slave) for Interbus Slave.
- Gateway (slave) for Profibus DP Slave.
S4Cplus with the option I/O Plus can be configured for fieldbus units from other
suppliers. For more details see the Product Specification RobotWare Options.
The inputs and outputs can be configured to suit your installation:
- Each signal and unit can be given a name, e.g. gripper, feeder.
- I/O mapping (i.e. a physical connection for each signal).
- Polarity (active high or low).
- Cross connections.
- Up to 16 digital signals can be grouped together and used as if they were a
single signal when, for example, entering a bar code.
- Sophisticated error handling.
- Selectable “trust level” (i.e. what action to take when a unit is “lost”).
