2.1
Overview and Application
The FieldConnex
®
Multi-Input/Output device (MIO) for PROFIBUS PA provides discrete inputs,
discrete outputs, 1 frequency input, or 1 counter to process control systems. The device is
suitable for DIN rail mounting and field installation with different housing options. The F2 type
housing is made of sturdy cast aluminum for installation in rough environments. Fieldbus and
sensor-actuator cable entries can be selected individually from a range of cable glands.
Optionally, either screw terminals or spring terminals can be chosen. Contact your
Fuchs representative for further information on housing options.
The device can be installed in hazardous areas Zones 1, 21, 2, 22, and Division 1, 2.
PROFIBUS PA and input/output sensor and actuator connections are rated intrinsically safe for
installation in Zone 0 and Division 1.
The device provides different configurable modes of operation.
The valve coupler mode allows connecting 4 low-power valves with 2 end position inputs per
valve.
The sensor input mode allows connecting up to 12 binary sensors. 4 sensor inputs are
designed to support vibrating forks for level control. One of these inputs is designed to support
a frequency or counter input.
The MIO is intended to be used as a replacement for Fuchs process interfaces FD0-
VC-Ex4.PA and FD0-BI-Ex12.PA.
For device configuration, a device type manager (DTM) for FDT-based frame applications is
available. Also, a device description (DD) for the Siemens Process Device Manager (PDM) is
available.
2.2
Modes of Operation
The device supports 12 hardware channels which can be configured as inputs and outputs.
The functional configuration of the channels is determined by selecting a dedicated mode of
operation.
Valve Coupler Mode
In the valve coupler mode, the channels 1, 4, 7, and 10 are used to control 4 low-power valves.
The channels 2, 3, 5, 6, 8, 9, 11, and 12 are used as valve position feedback inputs for
NAMUR proximity switches or mechanical switches. Condition monitoring functions like stroke
counter, partial stroke test, and travel time survey enable you to detect evolving faults, before
they become critical for the process control.
Refer to the technical data of the MIO for specification of compatible valves and sensors. A list
of compatible low-power valves and NAMUR sensors are available on the Fuchs
website.
FD0-VC-Ex4.PA Compatibility Mode
This mode allows the use of *D0-MIO-Ex12.PA* in an existing installation as a replacement for
FD0-VC-Ex4.PA. In order to activate this mode, use the GSD file of FD0-VC-Ex4.PA. The mode
is activated during the start-up of cyclic data exchange. Use the device type manager or device
description of the *D0-MIO-Ex12.PA* to adjust the device parameters according to the
replaced FD0-VC-Ex4.PA.
PROFIBUS Profile 3.02 Valve Coupler Compatibility Mode
PROFIBUS PA profile 3.02 defines an interoperability mode for a 4-channel valve coupler. The
corresponding GSD file is available on the PROFIBUS International website. Use the device
type manager or device description of the *D0-MIO-Ex12.PA* in order to adjust the device
parameters.
