Contents Please Read This Notice Successful application of the 1560-MBP card requires a reasonable working knowledge of the Allen-Bradley hardware to be interfaced with, and the application in which the combination is to be used.
Quick Start Guide Contents Quick Start Guide In this section we have assembled a simple step-by-step procedure for installing and making the 1560-MBP unit operational. This discussion presumes that the application decisions such as Modbus Plus addressing and hierarchy, SCANport cable length, etc. have been addressed prior to this point. Step-by-Step The following steps will allow the 1560-MBP to be setup in the shortest period of time (the following steps refer to the Allen-Bradley drive implementation.

Chapter 2 — Modbus Plus Port Functionality 2 Modbus Plus Port Functionality 2.1 Modbus Plus Communications Contents 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 1560MBP card. 2.1.
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 1560MBP unit. This map is detailed in Appendix A, and shown below.

Chapter 4 — Programming Considerations 4 Contents 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.

Chapter 4 — Programming Considerations Contents 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. 4.1.

Appendix B — Device Specific Hints Contents Appendix B Device Specific Hints SMC Dialogue Plus The SMC Dialogue Plus does not support Datalinks, therefore the configuration of SW1-7 and 8 should not include any of the Datalinks Enabled. If a Datalink is enabled, the SCANport Status LED will toggle, indicating an error in the SCANport communications. The version of SMC which was tested (Rev 1.05) had 88 parameters. Each parameter was accessible in the Modbus register listing shown in Appendix A.

As with the Data Out parameters, there are eight possible selections. These may be chosen by the programmer to meet the needs of the application.
Appendix C — Peer Cop Example Contents Appendix C Single Drive Peer Cop Application Example Overview This example shows how to configure a PLC to control and monitor a single drive using Peer Cop. Note that this example may easily be extended to 16 drives on one network. Additional sets of 16 drives may be controlled by adding Modbus Plus Network Option Modules to the PLC. In this example, a 984-785E is connected to a 1560-MBP controlling a 1336Plus drive.
Appendix C — Peer Cop Example Contents The 1560 MBP-1560 Dip Switch 2 Configuration is as follows: Switch Position Description 1 On Set the 1560-MBP Node Address 6 2 Off 3 On 4 Off 5 Off 6 Off 7 On Enable Global Data Control from a host.
Appendix C — Peer Cop Example Contents This configuration indicates that PLC words 40100 through 40131 will be sent in Node 7 (this PLC) Global Data. Since the 1560-MBP is configured to look at Node 7 as the Host, words 40110 will be the Drive Control word, and 40111 will be the Reference to the drive (The remaining registers are for 1560-MBP units located at nodes 1-5 (words 4010040109), and 7-16 (words 40112-40131).
Appendix C — Peer Cop Example Contents The Global Input Data from Node 6, starting with offset 1 for a length of 9 words, will be assigned to PLC registers 40200 through 40209.
Appendix C — Peer Cop Example Contents This allows a coil to control a specific function in the drive. You could use bit manipulation instructions operating on word 40100 (such as MBIT), but it is far simpler to just assign coils to specific functions, and then move these coils into the Control Word.
Appendix C — Peer Cop Example Contents Addressing Pay careful attention to the dip switch address configuration. EACH 1560-MBP on the network must have it own unique address. This MUST also be different from the PLC address. ALL drives should in general have their Host address set to the PLC ís address. Hints Note that the Stop bit is set to 1 to stop drive. If communication is lost, the PLC is unable to remotely stop the drive.
Appendix D — Mounting & Cabling Contents Appendix D Mounting and SCANport Cabling Instructions Mounting Instructions Following are the mounting dimensions and layout drawings for the enclosed style communication module, such as the 1560-MBP.

Appendix D — Mounting & Cabling Contents Cable Requirements SCANport cables are available in either Male to Male or Male to Female configurations. Cables of up to 10 meters (33 feet) can be connected from the SCANport device to the 1560-MBP. If a Port Expander is used, the cable length from the master to the Port Expander must be subtraced from the cable length used to connect the device to the expander (B1 + C = max 10 meters).
Appendix E — SCANport Datalinks Contents Appendix E SCANport Datalink Operation (Excerpted from A-B Publication 1203-5.2 - May 1995) In the following discussion, the term ‘Datalink’ is used extensively. When configuring some SCANport devices, the term ‘Adaptor I/O’ is used in place of Datalink. A Datalink is a type of pointer used by some SCANport devices to transfer information between a SCANport communication interface (such as the 1560-MBP) and a SCANport device (such as a VFD, SMP3, etc.).
