I have Modbus Devices Which Supports Modbus RTU (RS-485). It is connected to A Device(Moxa MB3480)  is connected to to it by RS-485 communication.The Moxa Device is there to convert Modbus RTU to MOdbus TCP/IP. Then the Moxa Device is Connected to S7-400h PLC . Now I want the data of the Modbus Device in MY PLC. I am using the Library Blocks for Testing But some parameters Like Connection ID, Remote PORT Number Values . I cant understand .i am Using Block( FB63-TSEND, FB64-TRCV, FB65-TCON, FB66-TDISCON, FB913-TCP_COMM, FB916-MOD_SERV, FB917-MB_PNHSV) .

As explained in sample project i called the FB917 in OB1,OB100 with the same instance DB.

Now I need the Parameter for ID(Connection ID) and Remote Port Number.

 You are not using TIA Portal right? I am only familiar with TIA portal.

Thanks,

Jay

Hi Jay

Thanks for the reply

I am not using TIA . I am using Step7 V5.6 as TIA does not support H-System

Hi Wüstenräuber

Thanks for the Reply

I am using a third party which is not configured in the hardware so I can't make connection so no connection ID is generated.

I don't know how to check Port Number, Can you Help.

Moxa Switch have a Ethernet port which is connected to the PLC pn-Port and 4-RS485 which is connected in the field I can Assign Different IP address to each(4-Input) port .and Each port is connected to 4-5 Devices.

i am not able to find the Device ID in the Parameter DB . 

I am connecting 4-5 Modbus Device with 1 Port.

Hello Arshad73,
the device ID is the input UNIT:

I tried the Input UNIT(In Global DB) but it is not connected to block I tried Modifying the Block Data But it is being Over written.  

Hello Kaulquappe 

Thanks for the Reply 

I found the Input UNIT(In Global DB) 

and It worked Again Thanks for your Help

HI Arshad

I also trying to establish the same. Can you send me your project for reference. Iam unable to make communication with the TCP/IP converter. Through modscan its working fine.
