Important User Information
Solid-state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.rockwellautomation.com/literature/) describes some important differences between solid-state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid-state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

About This Publication
Audience
This publication is designed to provide quickstart instructions for using CIP GENERIC and CIP Symbolic Messaging in Micro830™ and Micro850™ programmable logic controller (PLC). It makes use of sample programs to illustrate the basic steps that a user needs to perform to use the CIP messaging functions in Micro830 and Micro850 controllers.
To assist in the design and installation of your system, refer to the Micro830 and Micro850 Programmable Controllers User Manual publication 2080-UM002.
The beginning of each chapter contains the following information. Read these sections carefully before beginning work in each chapter.
•Before You Begin – This section lists the steps that must be completed and decisions that must be made before starting that chapter. The chapters in this quick start do not have to be completed in the order in which they appear, but this section defines the minimum amount of preparation required before completing the current chapter.
•What You Need – This section lists the tools that are required to complete the steps in the current chapter. This includes, but is not limited to, hardware and software.
•Follow These Steps – This illustrates the steps in the current chapter and identifies which steps are required to complete the examples using specific networks.
To be able to use the CIP messaging feature effectively, you need to be familiar with programming in function block diagram, structured text, and ladder programming.
This quick start works hand-in-hand with Micro830 and Micro850 Programmable Controllers User Manual, publication 2080-UM002.
Required Software
To complete this quick start, the following software is required:
•Connected Components Workbench™ revision 4 and later
Connected Components Workbench is the main programming software for Micro800 systems. It provides a choice of IEC 61131-3 programming languages (ladder diagram, function block diagram, structured text) with user defined function block support that optimizes machine control.
You will need the Connected Components Workbench software to write your function block programs, execute your function blocks, and see results.

Where to Start
Overview
This quick start instructions illustrate how you can use the CIP Generic and CIP Symbolic Client Messaging functions on Micro830 and Micro850 controllers. It includes two sample projects that provide step-by-step instructions on how to program using the CIP messaging function blocks and assign values to the parameters to make a simple query/command from a Micro850 Controller A to a Micro850 Controller B using both messaging features.
To learn more about the MSG_CIPGeneric and MSG_CIPSymbolic function blocks and their corresponding input and output parameters, see the Connected Components Workbench Online Help and MSG_CIPSYMBOLIC Function Block on page 35 and MSG_CIPGENERIC Function Block on page 39.

IMPORTANT To use the Micro800 CIP client messaging feature effectively, users need to have a basic understanding of the following:
•MSG_CIPGeneric and MSG_CIPSymbolic Function Blocks
See MSG_CIPSYMBOLIC Function Block on page 35 and MSG_CIPGENERIC Function Block on page 39.
•Programming and working with elements in the Connected Components Workbench software
You need to have a working knowledge of ladder diagram, structured text, or function block diagram programming to be able to work with function blocks, and input/output parameters. For tips and recommendations on programming CIP messaging instructions, see Programming Tips and Recommendations for Micro800 CIP Messaging Instructions (MSG) on page 49.
Hardware and Software Compatibility
The CIP Generic and CIP Symbolic Messaging features on Micro830 and Micro850 controllers are compatible with Connected Components Workbench revision 4 and firmware revision 4 and later.

Use CIP Symbolic Client Messaging
Introduction
Micro830 and Micro850 controllers support CIP Symbolic client messaging through the MSG_CIPSYMBOLIC function block. This feature enables the sending of CIP Symbolic messages through Ethernet or serial cable.
In this chapter, you will learn how to use the function block to send a write instruction from Controller A to Controller B. Specifically, it shows you how to create a program that will write a value to Controller B’s global variable, UDINT_FromA.

Create CIP Symbolic Program (Write)
At the end of these instructions, you should have created the following program in Connected Components Workbench in your Controller A project.
RUNG 1
Use COP instruction to convert value ’ValueToWrite’ to ’A_Data’ (USINT[1...4]) which will be used in message instruction
RUNG 2
If COP instruction is successful then trigger ’WriteValue’ to coil
RUNG 3
Send message to Controller B
Build the Code
1.Open the project you created for Controller A in the last chapter through Connected Components Workbench.
2.Configure the IP address, subnet mask and gateway of Controller A as shown.

3.On the Project Organizer pane, right-click Programs, and then select Add New LD: Ladder Diagram.
You can press F2 to rename the program. Press Enter.
4.Right-click CIP_Sym program, and then choose Open.
5.From the Toolbox, double-click Block to add it to the rung. Alternatively, you can drag and drop Block onto the rung. Your ladder rung should appear as shown.
6.Add COP instruction to the rung by typing COP on the Instruction Block Selector window that appears to filter the COP function block.
7.Choose COP. Then, click OK.
8.Create variables for the COP input parameters as shown.
To learn more about the COP input and output parameter descriptions, see COP Function Block on page 43.
TIP |
You can disregard the yellow warning sign that appears. This |
|
indicates that the software expects a different data type. |

Assign Values to the MSG_CIPSYMBOLIC Input Variables
1.Set the values for the input variables through the Initial Value column of the Global Variables table.
See MSG_CIPSYMBOLIC Function Block on page 35 for more information about MSG_CIPSYMBOLIC parameters.
2.Set the value for the A_CtrlCfg input variable as shown.
See CtrlCfg on page 35 for parameter details and description.
In this example, we write the value to controller B every
300ms, and set initial value as
300.Set A_CtrlCfg.Cancel to False. By default, this parameter is set to False.

3.Set the value for the A_SymCfg input variable as shown.
See SymbolicCfg on page 36 for parameter details and description.
Leave the initial value of A_SymCfg.Count at 0. The value of 1 is used for count if this value is left at the default value of 0.
4.Set the value for the A_TarCfg input variable as shown.
See TargetCfg on page 37 for parameter details and description.
Set A_TarCfg.ConnClose to False. By default, this variable is set to false.
IMPORTANT
5.Next, build and download the project to Controller A.
The value for A_Data input variable is automatically obtained from the COP instruction in rung 1.
Note that USINT is 8-bit data (whereas A UDINT is 32-bit data), so the A_Data input variable is a one-dimension array with four elements.
