An Advant Controller 450 communicates with the process through various types of sensors and
actuators connected to process interface units. Three variants of the I/O system are offered,
S100 I/O, S400 I/O and S800 I/O. The I/O systems are optimized for different use.
As the short presentation below illustrates, the S100 I/O is the most complete system with
respect to special functions.
Process events can be time-tagged. The time accuracy is determined by the applied I/O system
and the selected board type.
Cabling represents a large portion of the cost of installing a process control system. In order to
reduce this cost, a range of distributable I/O units (S400 I/O and S800 I/O) are available
covering the most common process signal types. The distributable I/O units communicate with
the controller through MasterFieldbus (S400 I/O) and Advant Fieldbus 100 (S800 I/O).
Large S100 I/O cluster can be distributed too by using an optical S100 bus extension.
This facilitates for example the location of I/O cabinets close to a remote switch gear.
It is, of course, possible to mix the different I/O systems in the same application if you wish.
This manual gives an overall presentation of the I/O systems. Since the I/O systems are common
to several Advant Controller products, the detailed information is collected in separate
documents as follows.
• S100 I/O: Hardware descriptions and technical data of I/O boards, connection units
and the S100 I/O bus extension.
