The VersaPoint product family is a modular automation system. With
VersaPoint modules you can easily add one module to the next and build
functional units that meet your automation requirements exactly.
A set of interconnected VersaPoint I/O modules can be selected to suit the
application, and connected as a slave on a Profibus-DP network. The
interface between the network and the modules is a VersaPoint Profibus-DP
Network Interface Unit (NIU).
The NIU is located to the left of the other modules. Together, the NIU and
the modules selected for the application function as an I/O Station. The I/O
Station can include up to 63 I/O modules.
Within the VersaPoint station the bus connection, power supply, and power
distribution for the devices connected to the bus terminal are realized by
connecting modules together on the DIN rail.
Sensors and actuators are easily wired to the VersaPoint I/O modules via
spring-clamp terminals on the modules' removable connectors. These
connectors can be keyed so that they cannot be mixed up. If a module must
be exchanged the wiring does not need to be removed. Just remove the
connector from the terminal.
