Hi Dears,

I have configured S7-1200 MOD-BUS TCP/IP By MB_server (active),I checked the operation  mod-bus simulator it is working fine no issues,  but the problem is when connecting the MOXA the data not receiving

Here are some details 

S7-1200 IP :- 192.168.0.100

Partner IP (MB_server Assigned ip ) - 192.168.0.20

1st Moxa device S7-1200 Modbus partner  details below

Moxa G3150 IP :- 192.168.0.20 (Same as above MB _ server i given this IP)

Moxa G3150 GSM IP:- 78.89.162.65

The First Moxa Device will sent data partner Moxa by GSM IP from that point i need to read the data of S7-1200

2nd Moxa device receive data from 1st Moxa  details below

Moxa G3150 IP :- 192.168.0.10 

Moxa G3150 GSM IP:- 78.89.162.67 

from the 2nd moxa i try read the data by modbus simulator  but device not connected error is coming

(Note :- Without connecting  the S7-1200 CPU through modsim the data Read write happening between these two Moxa device)

Is there any possibility to give default Gateway for S7-1200 how to slove the issue 

Regards

Hello,

pls draw your schema of devices with description for better understanding and attach jpg. Pls think that MB TCP Server isn't active.

Hi,

Here I attached the project and connection details 

Is there any possibilities to give the gateway to S7-1200 CPU

Hi

Find the attached document, Iam using MB_server to send data through the ModSim the data send and receive no issues.

While connect to MOXA at receiver end the data not receiving 

 Did you set the Router IP address in both PLC with the IP address of the respective MOXA device and tried to see whether it can work? Just a suggestion. Not sure whether it works.

In the IP configuration of the PLC there is option to use Router IP address. Try that in TIA and download to see whether it works.

Thanks,

Jay

Hi,

As you said I tried but not working, I have gone through Another setup Explained below

1. With Two 2 nos CPU-1500 i checked the Mod-bus communication as MB_server and MB_client the connection work fine but when i Connect the MOXA GSM device G3150 it is not working 

2. During the Moxa G3150 (GSM) connection in between two CPU 1200 PLC Configuration below

MASTER CPU 1200 IP Address:- 192.168.0.100

MODBUS (MB_Server) partner IP  :- 192.168.0.20 (THE Moxa Ip is Partner IP)

CLIENT CPU 1200 ip Address :-192.168.0.18

MODBUS(MB_Client)partner IP  :- 192.168.0.10 (THE Moxa Ip is Partner IP)

This configuration will work or not

most importantly MB_Server and MBClient will work or not, if any other block let me know 

Find the Attachment for more info

Hi Guys

The Issue resolved,

To communicate with MOXA i removed the partner ID i given the default IP 0.0.0.0 and moreover in the Device configuration I gave the Router IP as Moxa IP as a gateway then it started communicating

The another strange thing after establish the communication i checked with remote partner ID it is also working...

Thanks & Regards
