Modbus Specifications............................................................................. 9
The 3170-MBS Modbus Slave Communication Adapter can interface up to 8
Rockwell Automation FLEX and/or Integra I/O modules directly with any Modbus
Master. The following functionality is available:
Multi-drop on an RS-485 link with other Modbus compatible devices
Interface Analog and/or Discrete I/O directly to a Host
Add FLEX I/O into applications where other manufacturer’s devices are
already in use
The 3170-MBS module is simple to use, requiring only the setting of several dipswitch options. The Flex and Integra module data images are pre-mapped into
Modbus addresses to simplify reading and writing using standard Modbus
commands.
The 3170-MBS has read/write access to all Flex and Integra modules. This
allows a Host system to perform all functions necessary to get all I/O modules
functioning. All register data values can be accessed using Function Codes 3, 4,
6 and 16. Bit level Function Codes 1, 2, and 5 are also supported.

2 Functional Overview
2.1 Modbus Addressing Concepts
Modicon developed the Modbus addressing scheme around the data table and
I/O structure in Modicon PLCs. As a result, the Modbus protocol supports access
to the various data spaces in the Modicon PLC.
By far the most common data space used is the 4xxxx space using the Function
Codes 3, 6 and 16. This space is used to transfer 16 bit register values and can
be used to transfer bit mapped data. Using formal Modbus addressing
terminology, this data space actually starts at address 40001.
Access to the different data spaces is determined by the Function Code that is
used. The following chart shows the four different types of data spaces, the
numerical range of these spaces, and the Function Codes that are used to
execute read and write instructions within these data spaces. The following
illustration shows the relationship between the Modbus Function Codes and the
Modbus addressing scheme.

2.2 The Data Space in the module
One of the concepts, which are important to develop an understanding of, is the
relationship between the data space in the module and how this data can be
moved between the module and the Modbus Master.

User Manual Modbus Slave Interface Module
3.1 Mounting on a DIN-rail before installing the terminal base units
1 Position the Modbus adapter module A on a 35 X 7.5mm DIN-rail B
(Rockwell Automation pt. no. 199-DR1: 46277-3; EN 50022) at a slight angle.
2 Hook the lip on the rear of the adapter (A) onto the top of the DIN-rail (B),
and rotate the adapter module onto the rail.
3 Press the adapter module down onto the DIN-rail until flush. Locking tab (C)
will snap into position and lock the adapter module to the DIN-rail.
4 If the adapter module does not lock in place, use a screwdriver or similar
device to move the locking tab down while pressing the adapter module flush
onto the DIN-rail and release the locking tab to lock the adapter module in
place. If necessary, push up on the locking tab to lock.

3.2 Mounting (or Replacing) the module on an existing system
1 Remove the Modbus plug-in connector from the front of the adapter.
2 Disconnect any wiring jumpered to the adjacent terminal base.
3 Using a screwdriver or similar tool, open the lock and remove the module
from the base unit to which the adapter will be attached.
4 Push the flexbus connector toward the right side of the terminal base to
unplug the backplane connection.
5 Release the locking tab and remove the adapter.
6 Before installing the new adapter, notice the notch on the right rear of the
adapter. This notch accepts the hook on the terminal base unit. The notch is
open at the bottom. The hook and adjacent connection point keep the
terminal base and adapter tight together, reducing the possibility of a break in
communication over the backplane.
7 Complete the adapter mounting as shown below.
Attention: Make certain that the hook on the terminal base is properly hooked into the adapter.
Failure to lock the hook into the adjacent base/adapter can result in loss of communication on the
backplane.
8 If the adapter module does not lock in place, use a screwdriver or similar
device to move the locking tab C down while pressing the adapter module
flush onto the DIN-rail. Then release the locking tab to lock the adapter
module in place. If necessary, push up on the locking tab to lock.
9 Reinstall the module into the terminal base unit.

Each Flex or Integra module has 60 words of address space. 30 Input or Read
address and 30 Output or Write addresses. Data is mapped in two ways
Horizontal and Vertical.
With Horizontal addressing the adapter address the first input and output word
for each module incrementally. 40001 for module 0, 40002 for module 1 and so
on.
Vertical addressing increments the words for each module. For example, the
vertical read words for slot 0 start with 41001 and increment to 41015.

The following explains the operation of the LEDs.
LED Color Status Indication
Power Green On
Transmit Green Blink The Modbus port is transmitting data.
Receive Green Blink The Modbus port is receiving data. LED flashes on any character
COM
ERR
Amber Off
Normal state: The module is operating normally, with
communications being detected on the link
Blink
Modbus Communication Timeout: The port has not detected any
communications on the link for over 1 second. If the HOLD LAST
STATE dip switch is not set, the Input and Output images will be
forced to zero(0).
FLEX Backplane Communications Fail: The communication
adapter either does not detect any I/O modules plugged into the
backplane, or the backplane communications have failed.
activity, valid or invalid.
Normal State: When the error LED is off and the related port is
actively transferring data, there are no communication errors
Blink Periodic communication errors are occurring during data
communications. Error conditions that cause LED to blink include:
Bad Function Code
Invalid Register Address in command
Invalid Count value in command
Insufficient Characters in Modbus Packet
Checksum Error detected in packet
FLEX Backplane Communications Fail: The communication
adapter either does not detect any I/O modules plugged into the
backplane, or the backplane communications have failed

6.2 Troubleshooting: General
In order to assist in the troubleshooting of the adapter, the following table has
been put together. Use the following table to assist in application of the module,
but if additional questions or problems arise, please do not hesitate to contact us.
Problem Description Steps to take

If connected to the host and no communications are occurring, verify
the following:
Polarity of RS-485 cable connections (Either RX LED on
continuously or not toggling at all)
Slave Address: Valid addresses range from 1 to 127. Verify that
the address is encoded into the dip switch correctly
Baud Rate
Stop Bits, Parity, and Modbus Mode. There are valid
combinations of these parameters which are supported by the
adapter hardware. Verify that the configuration is one of the
following:
Modbus RTU and ASCII Modes
8 Data Bits, No Parity, 1 Stop
8 Data Bits, No Parity, 2 Stop
8 Data Bits, Odd Parity, 1 Stop
8 Data Bits, Even Parity, 1 Stop
Modbus ASCII Mode Only:
7 Data Bits, No Parity, 2 Stop
7 Data Bits, Odd Parity, 1 Stop
7 Data Bits, Even Parity, 1 Stop
7 Data Bits, Odd Parity, 2 Stop
7 Data Bits, Even Parity, 2 Stop
Modbus Mode: Verify that the host and the adapter are talking the
same implementation of the protocol, either RTU or ASCII.
all manufacturers adhere to the same +/- and A/B labeling
conventions. Do not be afraid to experiment with swapping the
polarity, no damage will occur to the hardware.
Periodic communication errors are occurring during data
communications. Error conditions which cause LED to blink include:
Bad Function Code
Invalid Register Address in command
Invalid Count value in command
Insufficient Characters in Modbus Packet
Checksum Error detected in packet
FLEX Backplane Communications Fail: The communication
adapter either does not detect any I/O modules plugged into the
backplane, or the backplane communications have failed
(and the Input Image) in the adapter will be forced to zero whenever
communications with the host has not been detected for over 1
second. The Outputs will be re-established by the adapter as soon
as a valid write command is received from the host.
To prevent the Toggling of the outputs, either set the HOLD LAST
STATE dip switch (S2 position 8), and/or assure the reliability of the
communications.

7.1 Application Example
Use the information provided with your I/O to fill in the work sheets (page 38).
This will help you to decide the best way to address each I/O block.
In most applications Analog I/O will be addressed using the Vertical method.
Discrete I/O must be addressed using the Horizontal method only.
The Input Data will be read vertically as holding registers
The Underrange bits will be read as inputs
The Configuration Selection bits will be written as coils.

The following Return Material Authorization (RMA) Policies and Conditions
(collectively, "RMA Policies") apply to any returned product. These RMA Policies
are subject to change by ProSoft Technology, Inc., without notice. For warranty

between the RMA Policies and the Warranty, the Warranty shall govern.
8.1.1 Returning Any Product
a) In order to return a Product for repair, exchange, or otherwise, the
Customer must obtain a Return Material Authorization (RMA) number
from ProSoft Technology and comply with ProSoft Technology shipping
instructions.
b) In the event that the Customer experiences a problem with the Product for
any reason, Customer should contact ProSoft Technical Support at one of
the telephone numbers listed above (page 45). A Technical Support
Engineer will request that you perform several tests in an attempt to
isolate the problem. If after completing these tests, the Product is found to
be the source of the problem, we will issue an RMA.
c) All returned Products must be shipped freight prepaid, in the original
shipping container or equivalent, to the location specified by ProSoft
Technology, and be accompanied by proof of purchase and receipt date.
The RMA number is to be prominently marked on the outside of the
shipping box. Customer agrees to insure the Product or assume the risk
of loss or damage in transit. Products shipped to ProSoft Technology
using a shipment method other than that specified by ProSoft Technology,
or shipped without an RMA number will be returned to the Customer,
freight collect. Contact ProSoft Technical Support for further information.
d) A 10% restocking fee applies to all warranty credit returns, whereby a
Customer has an application change, ordered too many, does not need,
etc. Returns for credit require that all accessory parts included in the
original box (i.e.; antennas, cables) be returned. Failure to return these
items will result in a deduction from the total credit due for each missing
item.

This Limited Warranty ("Warranty") governs all sales of hardware, software, and
other products (collectively, "Product") manufactured and/or offered for sale by
ProSoft Technology, Incorporated (ProSoft), and all related services provided by
ProSoft, including maintenance, repair, warranty exchange, and service
programs (collectively, "Services"). By purchasing or using the Product or
Services, the individual or entity purchasing or using the Product or Services
("Customer") agrees to all of the terms and provisions (collectively, the "Terms")
of this Limited Warranty. All sales of software or other intellectual property are, in
addition, subject to any license agreement accompanying such software or other
intellectual property.
8.2.1 What Is Covered By This Warranty
a) Warranty On New Products: ProSoft warrants, to the original purchaser,
that the Product that is the subject of the sale will (1) conform to and
perform in accordance with published specifications prepared, approved
and issued by ProSoft, and (2) will be free from defects in material or
workmanship; provided these warranties only cover Product that is sold as
new. This Warranty expires three (3) years from the date of shipment for
Product purchased on or after January 1st, 2008, or one (1) year from the
date of shipment for Product purchased before January 1st, 2008 (the
"Warranty Period"). If the Customer discovers within the Warranty Period
a failure of the Product to conform to specifications, or a defect in material
or workmanship of the Product, the Customer must promptly notify
ProSoft by fax, email or telephone. In no event may that notification be
received by ProSoft later than 39 months from date of original shipment.
Within a reasonable time after notification, ProSoft will correct any failure
of the Product to conform to specifications or any defect in material or
workmanship of the Product, with either new or remanufactured
replacement parts. ProSoft reserves the right, and at its sole discretion,
may replace unrepairable units with new or remanufactured equipment.
All replacement units will be covered under warranty for the 3 year period
commencing from the date of original equipment purchase, not the date of
shipment of the replacement unit. Such repair, including both parts and
labor, will be performed at ProSoft’s expense. All warranty service will be
performed at service centers designated by ProSoft.
b) Warranty On Services: Materials and labor performed by ProSoft to repair
a verified malfunction or defect are warranteed in the terms specified
above for new Product, provided said warranty will be for the period
remaining on the original new equipment warranty or, if the original
warranty is no longer in effect, for a period of 90 days from the date of
repair.
