Introduction

Remote I/O stations are signal modification devices that act as an interface for signals between
field devices and process control systems. The individual components, i.e., the I/O modules,
com units, and power supplies, are plugged into the slots on the backplane. Com units are
available for various standard buses and form the interface between the I/O modules and the
process control system. Power supplies are used to power the I/O modules and com units.
The bus systems detailed below are supported.
Bus system
PROFIBUS DP/DP-V1
MODBUS RTU
MODBUS TCP
FOUNDATION fieldbus H1
This manual sets out how to work with the hardware. For information on how to configure the
com units and I/O modules, refer to the software manual for the relevant com unit in use.
