Interbus-S Module
The Interbus-S digital I/O module (part number 41-30-0300) is optional and is supplied only when it is
specified at the time of order. When it is included in the controller enclosure, it provides another I/O
interface, usually to an external, remote PLC. The module is housed inside the CS4000 Mini
Controller with Ethernet enclosure. See Figure 3-4 on page 3-7.
Figure 3-11 shows the position of LEDs on the side of the Interbus-S module. Each LED lights up
steadily to indicate the current state of I/O connections.
