enclosure walls where it is dissipated by the external cooling
fins.
I/O SERVER MODULE INTERFACE FEATURES
High density -
Four units mounted on the IOS carrier board
provide up to 128 isolated input points in a single system
slot.
Local ID
- Each IOS module has its own 8-bit ID PROM
which is accessed via data transfers in the "ID Read" space.
8-bit I/O
- Port register Read/Write is performed through 8-
bit data transfer cycles.
I/O SERVER MODULE SOFTWARE LIBRARY
IOS MODULE Win32 DRIVER SOFTWARE
Acromag provides a software product (sold separately) to
facilitate the development of Windows Embedded Standard
applications interfacing with I/O Server Modules installed on
Acromag Industrial I/O Server systems. This software (Model
IOSSW-DEV-WIN) consists of a low-level driver and Windows
32 Dynamic Link Libraries (DLLS) that are compatible with a
number of programming environments including Visual C++,
Visual Basic.NET, Borland C++ Builder and others. The DLL
functions provide a high-level interface to the IOS carrier and
modules eliminating the need to perform low-level reads/writes
of registers, and the writing of interrupt handlers.
IOS MODULE LINUX SOFTWARE
Acromag provides a software product (sold separately)
consisting of Linux software. This software (Model IOSSW-
API-LNX) is composed of Linux libraries designed to support
applications accessing I/O Server Modules installed on
Acromag Industrial I/O Server systems. The software is
implemented as a library of
“C” functions which link with
existing user code.
2.0 PREPARATION FOR USE
UNPACKING AND INSPECTION
Upon receipt of this product, inspect the shipping carton for
evidence of mishandling during transit. If the shipping carton is
badly damaged or water stained, request that the carrier's agent
be present when the carton is opened. If the carrier's agent is
absent when the carton is opened and the contents of the carton
are damaged, keep the carton and packing material for the
agent's inspection.
For repairs to a product damaged in shipment, refer to the
Acromag Service Policy to obtain return instructions. It is
suggested that salvageable shipping cartons and packing
material be saved for future use in the event the product must be
shipped.
This board is physically protected with
packing material and electrically
protected with an anti-static bag during
shipment. However, it is recommended
that the board be visually inspected for
evidence of mishandling prior to
applying power.
The board utilizes static-sensitive components and should only
be handled at a static-safe workstation.
BOARD CONFIGURATION
Power should be removed from the board when installing IOS
modules, cables, termination panels, and field wiring. Refer to
your IOS module documentation for configuration and assembly
instructions. Model IOS-440 digital input boards have no
hardware jumpers or switches to configure.
CONNECTORS
IOS Field I/O Connector (P2)
P2 provides the field I/O interface connections for mating IOS
modules to the carrier board. P2 is a 50-pin female receptacle
header (AMP 173279-3 or equivalent) that mates to the male
connector of the carrier board (AMP 173280-3 or equivalent).
This provides excellent connection integrity and utilizes gold
plating in the mating area. The field and logic side connectors
are keyed to avoid incorrect assembly.
P2 pin assignments are unique to each IOS model (see Table
2.1) and normally correspond to the pin numbers of the field I/O
interface connector on the carrier board (you should verify this for
your carrier board).
