Environment and Enclosure
This equipment is intended for use in a Pollution
Degree 2 industrial environment, in overvoltage
Category II applications (as defined in IEC
publication 60664–1), at altitudes up to 2000
meters without derating.
This equipment is considered Group 1, Class A
industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring
electromagnetic compatibility in other
environments due to conducted as well as radiated
disturbance.
This equipment is supplied as “open type”
equipment. It must be mounted within an
enclosure that is suitably designed for those
specific environmental conditions that will be
present, and appropriately designed to prevent
personal injury resulting from accessibility to live
parts. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent
sections of this publication may contain additional
information regarding specific enclosure type
ratings that are required to comply with certain
product safety certifications.
See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations
of the degrees of protection provided by different
types of enclosures. Also, see the appropriate
sections in this publication, as well as the
Allen–Bradley publication 1770–4.1, (“Industrial
Automation Wiring and Grounding Guidelines”),

Overview of FLEX I/O and Your PROFIBUS Adapter Module
Purpose of the 1794ĆAPB
FLEX I/O Adapter
1–5
The 1794-APB is a FLEX I/O adapter that interacts with the FLEX
I/O backplane and any PROFIBUS DP master/scanner controller on
a PROFIBUS DP network.
The 1794-APB module is a slave device to the DP master/scanner,
and is a master controller of the FLEX I/O system where it is
installed.
The I/O data exchange occurs as follows: Output data is sent from
the DP master/scanner controller across the PROFIBUS DP network
to the 1794-APB adapter. The adapter then automatically transfers
the data across the FLEX I/O backplane to the output modules.
Inputs from the input modules are collected by the FLEX I/O adapter
via the backplane and sent across the PROFIBUS DP network to the
DP master/scanner controller.

Diagnostic Indicators
Diagnostic indicators are located on the front panel of the adapter
module. They show both normal operation and error conditions in
your FLEX I/O system. The indicators are:
• Device status (STATUS)
• Communication link status (PROFIBUS)
Upon power-up, the adapter goes to an initialization state and
performs a self-test (memory check, data memory clear, CRC on
code). The indicators also go through a self-test sequence. If a failure
occurs, the adapter transitions to a faulted state and waits for reset
(cycle power). Otherwise, the adapter begins monitoring the network
(run state) for messages.

Connections are provided for connecting the required 24V dc power
to the front of the module. The power wiring can be daisy-chained to
the terminal base unit located next to the adapter to supply power to
the module installed in that base unit.

Overview of FLEX I/O and Your PROFIBUS Adapter Module
Chapter

How Communication Takes
Place and I/O Image Table
Mapping
What this Chapter Contains
Communication Over
the I/O Backplane
In this chapter, you will learn about:
• communication over the FLEX I/O backplane (between the
PROFIBUS adapter and the I/O modules)
• how data is mapped into the I/O image table
One 1794-APB PROFIBUS adapter can interface with up to eight
terminal base units with installed FLEX I/O modules, forming a
FLEX I/O system of up to eight slots. The adapter communicates to
other network system components over the PROFIBUS network.
The adapter communicates with its I/O modules over the backplane.

The I/O map for a module is divided into read words and write
words. Read words consist of input and status words, and write
words consist of output and configuration words. The number of
read words or write words can be 0 or more. The length of each I/O
module’s read words and write words vary in size depending on
module complexity. Each I/O module will support at least 1 input
word or 1 output word. Status and configuration are optional,
depending on the module.
( '#" * #)!% 2–2
How Communication Takes Place and I/O Image Table Mapping
For example, a 16 point discrete input module will have up to 2 read
words and 1 write word.

Check the I/O map for each module for the exact mapping.
Polled I/O Structure
The first word of output data received by the adapter is the Adapter
Status Word. Output data is received by the adapter in the order of
the installed I/O modules. The Output data for Slot 1 is received
first, followed by the Output data for Slot 2, and so on up to slot 8.
All bits in the output status word are reserved
The first word of input data sent by the adapter is the Adapter Status
Word. This is followed by the input data from each slot, in the order
of the installed I/O modules. The Input data from Slot 1 is first after
the status word, followed by Input data from Slot 2, and so on up to
slot 8.

How Communication Takes Place and I/O Image Table Mapping
Possible causes for an I/O module fault are:
•
•
•
•
•
transmission errors on the FLEX I/O backplane
a failed module
a module removed from its terminal base
incorrect module inserted in a slot position
the slot is empty
The node address changed bit is set when the node address switch
setting has been changed since power up. The new node address does
not take effect until the adapter has been powered down and then
powered back up. Until this power cycling occurs, the node address
switches will not match the actual node address.

are listed below. Additional modules will be added as they are
developed.

Bit 00-03
Words 8 and 9
Definition
Channel calibration selection bit. When this bit is set (1), the channel can
be calibrated using the calibration clock bit (CK). Bit 00 corresponds to output
channel 0, bit 01 corresponds to output channel 1, it 02 corresponds to output
channel 3, bit 03 corresponds to output channel 4
Bit 04
Gain/Offset selection bit (GO). - When this bit is cleared, a 0 to 1 to 0
transition of the CK bit performs on offset calibration. When this bit is 1, the
module is directed to do a gain calibration.
Bit 05
Calibration clock bit (CK). - When this bit is set to 1 (calibration mode), the
calibration coeffiicient for the selected channels is accepted. When this bit is
reset (0), the accepted calibration coefficients for the selected channels are
stored, applied, and the calibration mode exited. Monitor status bits DN and
BD for succesful calibration.
Bit 06
Quick Calibration bit (QK). - Normally reset (0). When this bit is set (1)
during a calibration sequence, the calibration coefficient is stored to all
related configurations for the selected channels. NOTE: Although this method
of calibration quickly calibrates the selected channels, they will not be within
the rated accuracy of the module.
Bit 07
Revert to defaults bit (RV). - Normally reset (0). When set (1) during a
calibration procedure, default values for selected channels are used for the
calibration coefficient. NOTE: They will not be within the rated accuracy of the
module.
Bits 08-11
(10-13)
2–47
Request for hold outputs (Q). - Channel request bits that instruct an output
to hold its output level when EN transitions from 1 to 0 to 1. When EN is 0,
outputs go to a safe state dictated by S1/S0. When EN returns to 1, the
outputs will hold their level until the output data equals the output level.
P0-P3 indicates channels holding. Output read back data shows what level is
being held. Q0 = bit 08 (10) = channel 0; Q1 = bit 08 (10) = channel 1, etc.
Bit 12 (14)
Interrupt Toggle bit (IT) - This bit, when set (1), permits interleaving of
module interrupts ensuring exchange of critical data when channels are
configured for their fastest update times. RTSI and no low pass filter" must
be 0 in order for the module to recognize this feature. This groups data
update rates for all channels to the slowest configuration setting of any of the
channels. In addition, channel update rates for all channels with a 7.5ms
update rate are reduced to 5.0ms. When reset (0), real time sampling and
filter features are enabled.
Bit 13 (15)
Transparent bit (TR). - This bit, when set to 1, permits configuration to be
changed without using the IC bit.
Bit 14 (16)
Set to 1
Bit 15 (17)
Initiate Configuration bit (IC). - When set (1), instructs the module to enter
configuration mode. Present configuration data prior to or coincident with IC
being set. Once IC returns to 0, the configuration is applied and any subquent
configuration information is ignored until IC is toggled.

The default values reflect the maximum number of read/write words.
You can change the I/O data size for a module by reducing the
number of words mapped into the adapter module, as shown in
optimal sizes.
Optimal sizes are the settings that provide optimal data to and from
the I/O module. You need a software configuration tool to change the
size. Make sure the FLEX I/O adapter is compatible with the
configuration tool you choose.
The optimal settings provide the fastest network time by only
mapping read and write words used by the I/O modules. If you
reduce your data sizes to only include optimal data, you can only
change your configuration data with a software tool. If you need to
change configuration information on an optimal basis, your data size
must be large enough to include the necessary words.

Connect the Adapter to the
PROFIBUS DP Network
What this Chapter Contains
The DP Physical Layer
This chapter describes:
• the DP physical layer
• using line types A and B
• equipment you need
• how to connect the adapter to the network
• how to terminate the network
The PROFIBUS network media is a balanced transmission line
corresponding to the standard EIA RS-485, terminated at both ends.
Both line A and line B types are available, depending on your system
requirements.
Specifications and guidelines for DP media:
• linear bus, terminated at both ends
• drop cables (preferably no longer than .30m), no branches
• shielded twisted pair
• max. line length between 100 and 1200m (depending on baudrate
and cable type)
• number of stations: 32
• DP baudrates: 9.6, 19.2, 93.75, 187.5, 500 Kbit/s and 1.5M bit/s
Use the following table to determine what line type will best meet
your needs.

Connect the Adapter to the PROFIBUS DP Network
Cabling and Equipment
Required for Line A Type
Line A cabling can support baudrates as high as 1.5M bits/s.
Cables
You need a shielded twisted pair cable for your cabling (bus
segments or drop cables). Any line A cable available on the market
can be used to connect your adapter to a PROFIBUS network.
TĆjunction Connectors
You need t-junction connectors to connect your droplines to bus
segments. You can use any t-junctions available on the market.
Termination Blocks
Termination blocks are only needed if the devices on the end of the
network do not have built-in terminating resistors. If you need
termination blocks, you can use any termination blocks available on
the market.
Bus Connector
Connect your adapter to the PROFIBUS DP network by attaching a
bus connector to the female 9 pin D-Sub connector on the front of
the module.
For detailed information on the topology and
IMPORTANT cabling for line A, see the PROFIBUS Standard

Connect the Adapter to the
Network
For line A or B connections, use bus segments with t-junctions and
termination blocks to form the PROFIBUS media (trunk cable). Use
termination blocks to terminate the line at each end of the trunk
cable. Use drop cables to connect devices to the network.
The maximum number of stations on the same network is 32.

Communication Takes

%# &$# "#%# %

A data exchange between the master and slave cannot be performed
until check configuration and send parameter data are issued. Each
time you power-up the network, the master sends check
configuration and send parameter data to the slave (FLEX I/O
adapter).
Check configuration data determines or checks the number of input
and output words used by each FLEX I/O module.
Send parameter data contains device-specific parameters you
define for each FLEX I/O module.
You need a software configuration tool to set the values associated
with these parameters. Since the FLEX I/O adapter is compatible
with any master, you can use any compatible configuration tool
available.
The device database (GSD) file is included on the software diskette
you received with your shipment of the FLEX I/O adapter. The GSD
file is used by your configuration tool to help you set up your
system. Your configuration tool automatically reads the GSD file and
extracts defaults used in the data exchange.
The file is in ASCII format and you can view it with any text editor.
A printed copy of your GSD file appears in Appendix B of this user
manual.
The user parameter data fields are not defined in the GSD file.
Depending on the format you choose, you may have to manually edit
these values with your configuration tool.
For more information on how you define and enter these user
parameter values, refer to the documentation associated with your
master and software configuration tool.

Entering User Parameter
Data
Send parameter data is comprised of a string of octets (1–32) that
contain 244 bytes of data:
• octets 1–7 contain data specific to the:
– PROFIBUS standard
– defaults contained in the database (GSD) file
• octets 8–32 are user configurable and contain user parameter
data. User parameter data consists of these formats:
– auto configure
– condensed
– full
The following illustration shows the structure of the send parameter
data table.

If the send parameter data is received with no user parameter data,
the flags byte is set to zero which selects:
• auto configure
• reset outputs to zero on fault
• reset inputs to zero on fault
The reserved bits must be set to zero to prevent undesired firmware
update behavior. This is the default behavior of the module as
defined in the GSD file.

Auto Configure Format
The Auto Configure format allows you to change modules without
affecting the User Parameter or Check Configuration data. This
format provides no keying from the master on the I/O modules
installed in the FLEX I/O system. The installed module at power-up
is taken as the key.
If you change a module while it is being controlled by a master, a
minor recoverable fault will occur. To recover from this fault, you
must replace the module with an identical module type.

Condensed Format
The condensed format consists of the flags byte and the module key
parameter for each of the eight slots. This parameter dictates which
I/O module must be installed. If at any time the actual module ID
does not match this module key, the slot will be considered in fault
and the following occurs:
• STATUS LED flashes red/off
• an error bit in the poll response data is set
• a diagnostic bit in the Ext_Diag_Data field returned in the Read
DP–Slave Diagnostic Information message response is set
All eight slots must be configured. The size for this format is always
17 bytes (including the flags byte). The condensed format structure
must be repeated for each of the eight slots.

When you use the condensed format, no safe state data can be
defined, thus the safe state data is left at the power up default of all
zeroes. Setting the Fault Action in the byte to Use Safe State with
this format is the equivalent of setting Reset to Zero.

Full Format
The full format consists of the flags byte and four parameters for
each of the eight slots. The module key parameter is the same for the
full format as defined by the condensed format, but adds three more
parameters for each slot.
Use the full format to:
• provide Safe State values for output points
• send FLEX I/O module configurations once (when you send
parameters) instead of every poll
• configure data sizes to reduce the size of data required during run
mode
You must configure all eight slots. The minimum size is 25 bytes (no
slots have FLEX I/O module configuration or safe state data). The
maximum size is 237 bytes (the size of the PROFIBUS user
parameter area).

Configure the Adapter for Master/Slave Communication
Entering Check
Configuration Data
On a PROFIBUS DP network, the I/O data exchanged between the
PROFIBUS DP master and a DP slave is encapsulated into logical
modules. The total I/O data exchanged between a PROFIBUS DP
master and a DP slave device comprises a set of logical modules
which is defined in the check configuration data.
Each physical slot of the FLEX I/O system is represented by two
logical modules (one input and one output). When the FLEX I/O
adapter is powered-up, the check configuration message configures
the module format (input and output words) and defines the size of
the modules within the device. When the sizes are configured, the
I/O data can be optimized to remove unused data from the data
stream.
Both input and output sizes can be configured. If a slot is empty, or if
either the input or output module is zero length, the specific
identifier for an empty module (free place) must be used.
If the end of the identifiers is reached before all slots have been
configured, the remaining slots are configured as empty.
The first two modules allocated are for the adapter itself, and must
always be a 1 word input module and a 1 word output module,
regardless of what parameter format you choose. The adapter uses
these words for adapter status information. Modules for each of the
individual slots (FLEX I/O modules) must also follow these word
assignments.
The format of the adapter status word is defined in the following
table:

The adapter expects the identifier area for each of the eight FLEX
I/O slots to be 2 bytes. The DP input/output identifier and all specific
DP identifiers (except the empty module) are not supported.

A valid check configuration message updates the internal
configuration. The updated internal configuration is then returned in
the message response.

Troubleshooting with the
Indicators
In this chapter, we describe how to use the adapter’s indicators for
troubleshooting.
Locate the two bi-color indicators on the front panel of the adapter.
They show both normal operation and fault conditions in your Flex
I/O PROFIBUS system. The indicators are:
• STATUS – this indicator provides device status
• PROFIBUS – this indicator provides communication link status
Use the following table to determine the indicator conditions and
status.

OD, CRL ( for FMS) DP slave database,and bus parameters
whenever the coprocessor’s working RAM configuration is
reinitialized.
application layer

Parameters are station address, maximum address and baud
rate. These can be changed using the Local Station Manager
or your compatible programming tool.
client
the FMS device that makes use of resources to perform some
type of application function.
CLOSE command
in FMS, terminates the connection with a remote node on the
network.
communication object model
describes the externally visible behavior associated with an
FMS service or group of services. Three types of
communication object models are domain objects, program
invocation objects and variable objects.
CREF

communication parameters
parameters within the PROFIBUS communication layers
that control the communication process. They are used to
configure and indicate current status of communication and
consist of the OD, CRL, bus parameters for FMS, and slave
database and bus parameters for DP.
G–2

Windows version 3.1. This program transfers data
(FDL,CRL, OD, station address, communication rate, and
maximum station address) between the PC and the
coprocessor over RS-232.
logical module
DP protocol describes I/O data exchanged between a PLC
master and a slave device as a set of logical modules (up to
