2 Modbus Plus Port Functionality
2.1 Modbus Plus Communications
The 1560-MBP Modbus Plus card supports the Modbus Plus
protocol using proprietary technology licensed from Schneider
Automation. With the Modbus Plus capability, the module is
able to communicate data from Allen-Bradley SCANport
compatible devices to a Modbus Plus host PLC, and vice-versa.
The following discusses the functional capabilities of the 1560-
MBP card.
2.1.1 Supported MSTR Programming Commands
The 1560-MBP uses several of the available MSTR ladder
logic commands to transfer data when using a Modicon PLC.
These are overviewed below:
Read Data:The following types of data read commands are
supported:
MSTR Type 2 Read Data
This command reads data from any place within the
Modbus Register map. This command allows a Modbus
host to selectively read data from the 1560-MBP as
required for the application.
MSTR Type 6 Read Global Data
This command gets data from the Global Data being sent
from the 1560-MBP. The 1560-MBP returns 2 to 10 words
of Global data. This is the fastest method of reading
values from the MBP.
Write Data:The following data write commands are supported:
MSTR Type 1 Write Data
This command writes data to any place within the 1560-
MBP Modbus Register map. This command can be used to
selectively write configuration values to the SCANport
device. In addition, if the Global Data Command Enable dip
switch is disabled, this command can be used to write to
the SCANport Control and Reference words (Modbus
addresses 40001 to 40010).
Chapter 2 — Modbus Plus Port Functionality

Contents
MSTR Type 5 Write Global Data
This command is used in a host processor to ‘publish’ Global
Data which all slaves on the Modbus Plus highway may
access.The 1560-MBP units can be configured to read the
Control and Reference values from this Global Data table.
2.1.2 Modbus Register Map
A pre-defined register map has been provided in the 1560-
MBP unit. This map is detailed in Appendix A, and shown
below. The full memory map is dependent on the A-B device
which is connected to the 1560-MBP unit.
On power-up, the 1560-MBP unit polls the remote device
and determines the maximum number of parameters that
exist in the SCANport device. If the number is greater than
2000 the parameter list is limited to 2000.

4 Programming Considerations
Transferring data to/from the 1560-MBP is performed either
using the standard MSTR instruction, or using the Peer Cop
functionality available in some Schneider processors. (Note that
Peer Cop functionality is somewhat limited. See Appendix C.)
Specifically, the following functionality is supported:
MSTR Type 1 - Write data
MSTR Type 2 - Read data
MSTR Type 5 - Write Global Data
MSTR Type 6 - Get Global Data
The following sections will detail the programming requirements
for each of these commands, as well as discuss speed trade-
offs between the different commands. An application note
detailing the configuration of a Peer Cop solution is also
available in Appendix C.
4.1 Writing to the 1560-MBP
4.1.1 Global Data Enabled - MSTRType 5
If Global Data Control Mode is enabled, the 1560-MBP will look
to the Host’s Global Data space for the Control and Reference
values. All other values must be written by the host using the
MSTR Type 1 instruction in the PLC.
The location of the Control and Reference values in the Global
Data is determined by the 1560-MBP Modbus Plus address.
The 1560-MBP uses the following algorithm to obtain the values :
If Modbus Plus Address < 17
GlobalTable Index = ( Modbus Plus Address - 1 ) * 2
else if Modbus Plus Address < 33
GlobalTable Index = ( Modbus Plus Address - 17 ) * 2
else if Modbus Plus Address < 49
GlobalTable Index = ( Modbus Plus Address - 33 ) * 2
else if Modbus Plus Address < 65
GlobalTable Index = ( Modbus Plus Address - 49 ) * 2
Note
The Global Data Table has a limit of 32 words,
therefore there can only be 16 1560-MBP
units with Global Control Enabled on one
Host processor. Care must be exercised that
all 16 Global Control Enabled 1560-MBP
devices are in the same block of addresses.

allowing up to 16 1560-MBP units to be controlled. When the 1560-MBP
reads the Global Data it first examines the source node address to
assure it matches the dip switch configured Host Node Address, and
then retrieves the two words that relate to its node from the packet.

4.1.2 Host IssuedWrite Commands - MSTRType 1
If the Global Data Control Mode is not enabled, the 1560-MBP
will not look to the Global Data Table to obtain the Control and
Reference values. In this mode, the Host PLC must execute a
write command (MSTR Type 1) to the 1560-MBP to register
addresses 40001 and 40002, per the following drawing, to
control the drive.
MSTR Type 1 Accessible Data Registers: The memory map for the registers
which a PLC programmer can access from the 1560-MBP using the MSTR
Type 1 command. Note that a write to the Read Only space between 40011
and 40100 will place an Error Code in the MBP Status register.

Parameter Register Space
This register space contains the parameter table from the
SCANport device.This paramaters are stored in their
numerical order (example):
40101 = Parameter #1
40102 = Parameter #2
The full length of this space is a function of the SCANport
device connected. Max size is 2000 parameters.

Chapter 4 — Programming Considerations
In the example (at the bottom of the previous page) the 1560-MBP
responding at Node 37 would retrieve its control and reference values
from the 8th and 9th words of the Global Data block. In the Host PLC we
have placed this data in registers 40418 and 40419, as this corresponds
to the 8th and 9th position in the Global Data packet.

4.2 Reading from the 1560-MBP
Reading data from the 1560-MBP is independent of the Global
Data Control mode selection. There are two methods for
obtaining data from the 1560-MBP units as outlined in the
following section.
4.2.1 Global Data - MSTRType 6
The 1560-MBP publishes Global Out Data which can be accepted by any
other node on the Modbus Plus port.The structure of the Global Data sent
out in is as follows :
Global Data from each 1560-MBP unit: Note the minimum
length of 2 words can be increased up to 10 words by
selectively enabling Datalinks using the dip switches
This instruction would write one value into parameter 19 of the device attached to
1560-MBP node address 37. In the 1560-MBP register map this would be register
40119.

40005 = 37 MBP Node address to write to
40006 = 1 Slave Input Path for routing
40010 = Source of the data to the
device attached to the 1560-MBP
Note that the Slave Input Path value must be
entered in order for the command to execute
successfully. Valid values are from 1 to 8. Any
other values will cause the command to fail.

Chapter 4 — Programming Considerations
In the example we configured the Allen-Bradley device to use Datalink output words.
The MSTR 6 instruction (Read Global Data), when programmed in a Host PLC, will
retrieve the Global Data from the 1560-MBP and place it in the Host PLC register
space beginning at address 40510.

Please note that not all A-B Scanport devices
support Datalinks. In particular, the SMC Dialogue

Plus do not enable Datalink Messaging.
4.2.2 Host Issued Read Commands - MSTRType 2
If the PLC Programmer does not want to use Global Data or if
there is a desire to read more data out of the 1560-MBP, the
MSTR Type 2 Read Command can be used.The MSTR Type 2
Read command has access to all available parameter values
(40101 to 40xxx), in addition to the Control and Status registers
(40001 to 40100).
