The next step is to create a program.

IF RJ71SEIP91_1.stEIPCls1_P1.uSet_CommunicationStartupRequest_D = 0
AND RJ71SEIP91_1.bSts_ModuleReady
THEN
RJ71SEIP91_1.stEIPCls1_P1.uSet_CommunicationStartupRequest_D := 1;
END_IF;

FOR iCounter:=0 TO 9 DO
RJ71SEIP91_1.stEIPCls1_P1.unArea_Class1OutputDataArea_D[iCounter]:=0;
END_FOR;

IF NOT RJ71SEIP91_1.stEIPCls1_P1.bnSts_Class1Error_Connection_D[1] THEN
RJ71SEIP91_1.stEIPCls1_P1.unArea_Class1OutputDataArea_D[0]:=12;
RJ71SEIP91_1.stEIPCls1_P1.unArea_Class1OutputDataArea_D[1]:=34;

Install EDS File

The next step is to install the EDS File for RJ71SEIP91-T4.

Click the “Install” button at the bottom.

Install the RJ71SEIP91-T4 EDS File downloaded from Mitsubishi’s website.

Done!

Resigter

Now enter the Tag Set screen and click on Registration All to publish the variables in the project for use in the Ethernet/IP network.

Select all Tags and proceed with Register.

Done!

Add RJ71SEIP91-T4

Now click the + button in the Toolbox to add RJ71SEIP91-T4.

Switch to the Ethernet/IP Node Settings screen.

Node Address

Node Address is set to the IP address of Mitsubishi’s RJ71SEIP91-T4.

Model Name

The Model Name should of course be set to RJ71SEIP91-T4.

Revision

There is only one Revision.

Add RJ71SEIP91-T4

Finally, add an Ethernet/IP Node using the Add button at the bottom of the Toolbox.

Done!

Let’s go ahead and add the RJ71SEIP91-T4 that we just added.

Configure Connection

Sets parameters for connection to RJ71SEIP91-T4.

INPUT/Originator Variable

The INPUT/Originator Variable defines the variable to be transferred to the data coming from the RJ71SEIP91-T4. In this example, it is set to DataFromEagle.

OUTPUT/Originator Variable

The OUTPUT/Originator Variable defines the variable for the data to be sent to the RJ71SEIP91-T4. In this example, it is set to DataToEagle.

Open EDS File via EZ

We want to know the Instance number of the RJ71SEIP91-T4, so open the RJ71SEIP91-T4 EDS File in the EZ-EDS tool. Since we want to use the Exclusive Owner connection for this article, click Connection Manager>Connection1.

Scroll to the bottom to see the connection Path for Connection1 Exclusive Owner.

There are two variables there, Param21 and Param20.

Param21=Output data of RJ71SEIP91-T4 and Param20=Input data of RJ71SEIP91-T4.

Once you open the Params item from the EZ-EDS tool, open Param21-Assembly instance O->T.

Min Value is 1024, Max is 1087, and Default is clearly stated as 1024, so we know that Param21 starts at 1024. In the previous article, we said that RJ71SEIP91-T4 has a maximum number of Class 1 communications per Port up to 64. 1024+64-1=1087, which is exactly 64Connection.

Next, open Param20-Assembly instance T->O. It clearly states that Min Value is 768, Max is 831, and Default is 768, so we know that Param20 starts at 768. In the previous article, I said that RJ71SEIP91-T4 has a maximum number of Class 1 communications per Port up to 64. 768+64-1=831, which is exactly 64Connection.
