Chapter 1 Introduction This Quick Start Guide (QSG) provides instructions on how to configure an Allen-Bradley CompactLogix or ControlLogix Programmable Logic Controller (PLC) to communicate with a Mitsubishi A800 Variable Frequency Drive (VFD) with an EtherNet/IP interface card A8NEIP_2P. The objective of this document is to assist the users to quickly set up a Logix PLC to send commands to the VFD and receive status information and data from the VFD. The manual contains the necessary configuration information for the A8NEIP-2P Module, the Mitsubishi A800 VFD parameters and the Logix CPU using User Define Data types and Add On Instructions.

It is assumed that the user of this manual is familiar with the operation of Mitsubishi A800 drives and has sufficient knowledge of the A8NEIP_2P interface card. It is critical for the user to refer to the A8NEIP_2P and A800 instruction manuals when setting up the system for EtherNet/IP applications.

Note: The above IP address and subnet mask are valid only for the validation system. Proper IP address and subnet mask need to be set up for the application in hand. *See Section 3.2 to calculate Parameter Value based upon what Monitor Item is needed.

3.2 Calculating Read and Write Process Data Parameter Values Option Board Parameters 1320 thru 1343 are configure for Reading and Writing values using Implicit Messaging.

Parameters 1320 thru 1329 are for 10 values that the A800 Inverter Reads from the Network Master and 1330 thru 1343 are for 14 values that the A800 Inverter Writes to the Network Master.

Figure 3.2 Read and Write Definition

The Monitor Data (Item) Value in Hex is Offset by 2000 Hex then converted back to Decimal for entry into the appropriate Parameter Number.

Figure 3.2.1 Monitor Data Offset Table

3-6

The below table from the A800 Inverter Manual details all the Monitor Data available Items that can be selected for Parameter Settings. Only PID Set point (52 Dec = 34 Hex) can be used as a READ item. All values (including PID Set point) can be used as a Write Item.

Figure 3.2.2 Monitor Data Items Table

3-7

Using the above table and the proper Offset, in order to Read PID Set point* the Parameter value is calculated this way. This is from User Specific Mapping Example in the A800 Manual.

• 52 Dec = 34 Hex

• 34 Hex + 2000 Hex (Offset) = 2034 Hex

• 2034 Hex = 8244 Dec

Parameter 1320 = 8244

Figure 3.2.3 User Specific Mapping Read

Note: *In Order for the A800 Inverter to Read the PID Set point from the Network Master, the Inverter Must be in the PID Mode. Set Parameter 128 to either 60 or 61 for Network Mode.

Figure 3.2.4 PID P128 Network Setting

3-8

Using the above table and the proper Offset, in order to Write Input Power the Parameter value is calculated this way. This is from User Specific Mapping Example in the A800 Manual.

• 13 Dec = D Hex

• D Hex + 2000 Hex (Offset) = 200D Hex

• 200D Hex = 8205 Dec

Parameter 1330 = 8205

4.5 Rockwell Add-On Instruction (AOI) and Sample Code

AOIs are Rockwell Function Blocks that can be imported into any RSLogix5000 program. Once Imported then can be selected from the Add-On Tab in the editor. To Import an AOI file (*.L5X) right click on “Add-On Instructions” in the Controller Organizer and select “Import Add-On Instruction…”.

One AOIs example is provided. It will work in the Extended Speed Control Mode and in the Exclusive Owner Control Mode where Output Assembly Instance 21 and Input Assembly Instance 71 are used. Parameter 1318 (21) and 1319 (71) in User Defined Data Mapping Mode.

Figure 4.5.1 A8EIP_2P_ACDC_Drive_Profile_AOI Block

The program examples include two sub programs being called from the “Main Routine” Program. The “Sample1_UDT” runs the demo program using the User Defined Data Types and the “Sample2_AOI” runs the demo program using the AOI. The two sub programs cannot be called at the same time.

Figure 4.5.2 Main Task Program Structure

An AOI Library File (*.L5X) has also been created and included with the QSG.

A8NEIP_2P_ACDC_Drive_Profile_AOI.L5X – RSLogix5000 AOI File

4-20

In order to use the AOIs you need to create Controller Tags or Program Tags as Inputs and Outputs for each AOI used. In the program examples the AOIs use Program Tags.

These include:

1. Internal I/O data Tag

a. acdc_aoi

2. Sub Program Call Tags

a. ControlByAOI and ControlByUDT

3. Local I/O Tags

a. net_ctrl, net_ref, reset, run_fwd, run_rev, speed_ref (created by the user, one set for each AOI instance used)

b. Read, Write, Start_Fwd, Start_Rev (Local Bit Control for VFD and Parameter Read, Write)

c. VFD_PID_SP, VFD_SPEED_RPMs (Writing Register Values to VFD)

4.6 Rockwell Explicit Messaging and Sample Code

In order to Read and Write Parameters Explicit Messaging (Acyclic Data Exchange) MUST be used. There is no way to do this using Implicit (I/O) Messaging. This is accomplished using MESSAGE Tags and the MSG Command. See Section 9.2 of the Option Manual.

1. Create Controller Tags (MESSAGE Tags can only be Controller Tags)

a. GetParamMsg (Data Type: MESSAGE)

b. SetParamMsg (Data Type: MESSAGE)

c. Parameter_Feedback (Data Type: DINT)

d. Parameter_Source (Data Type: DINT)

3. Click on the “…” key in the Message Block to open the Message Configuration Window. Enter the following data.

a. Message Type = CIP Generic

b. Service Type = Get Attribute Single

c. Class = a2 Hex (See Section A.12 of Option Manual)

Terminology

Implicit (I/O Data) Messaging

Connections are established to move application-specific I/O data at regular intervals. These connections often are set up as one-to-many relationships in order to take full advantage of the producer-consumer multicast model. Implicit messaging uses UDP/IP resources to make multicast data transfers over Ethernet a reality.

Explicit Messaging Point-to-point relationships that are established to facilitate request-response transactions between two nodes. These connections are general purpose in nature and can be used to reach any network-accessible items within a device. Explicit messaging connections utilize TCP/IP services to move messages across Ethernet.

EtherNet/IP EtherNet/IP is the name given to the Common Industrial Protocol (CIP), as implemented over standard Ethernet (IEEE 802.3 and the TCP/IP protocol suite).

User Defined Data Type (UDT)

User-defined data types allow a user to organize the data to match a machine or process. This streamlines program development and creates self-documenting code that is easier to maintain. A user-defined data type stores all the data related to a specific aspect of a system. This keeps related data together and easy to locate, regardless of its data type.

Add On Instruction (AOI)

Add On Instructions are Rockwell Function Blocks (Self-contained Programs) that can be imported into any RSLogix5000 program to be called (used) as needed.

Electronic Data Sheet (EDS)

EDS files are simple text files used by network configuration tools to help you identify products and easily commission them on a network.

Common Industrial Protocol (CIP)

The Common Industrial Protocol (CIP) is a media independent, connection-based, object-oriented protocol designed for automation applications. It encompasses a comprehensive set of communication services for automation applications: control, safety, synchronization, motion, configuration and information.
