PM554 integration with ARG600 with customer's fixed IP SIM card.
Hi,
My customer having a requirement of pull out data from the oil well using Wireless technology(using SIM card) and display the same in remote control station.
Have designed a architecture with PM554-ET controller & ARG600 wireless gateway with single sim device and made a setup for well side.
We suceeded doing modbus program using Automation builer & Codesys sw and tried to read the data through Modpoll simulator software.
when come to integration part with ARG600. we cannot able to succeed. With the given fixed IP simcard(192.168.224.102), we tried to ping the ip address from the customer's wired LAN network and the same was successful, but using the same IP address tried to open the modbus 502 port with modpoll sw then the connection is not getting through.
we tried also port forwarding(D-NAT) in ARG600 considering SIM card as source and controller as destination but could not works.
Note : controller ETH port, ARG600 LAN port and test laptop are connected with ethernet basic switch. Pinging is happening between all this devices.
Fixed sim ip details
IP - 192.168.224.102 & subnet : 255.255.255.255
ARG600 LAN port IP(through this port controller is connected to ARG) - 172.168.220.10 & subnet : 255.255.255.0
PM554-ETH IP - 192.168.220.11 & subnet : 255.255.255.0
Anyone please help in this regards.
Herewith attached the photograph of the setup and also the architecture of the same.
Thanks in Advance... :-)

What is the IP assigned to your laptop.Do you have multiple IPs assigned to your network card?

This seems like a very interesting setup!
Can you please provide your feedback onthe below points
1)Did you purchase the SIM Ip from the ISP.The IP to me looks like a private IP?
2)If subnetmask is 255.255.255.0, as far as I know, the first three octets must be common to all nodes within that subnet.

Yes Mr. Rahilmohammed. Multiple Ips are assigned under advanced option from network card properties.

1) yes it is a private IP. Only from the owner private network can access this.
2. yes 1st 3 octets are common in all devices subnet.

Hi.if the subnet mask is 255.255.255.0，then your wired network nodes must have the first three octets as common
Ex:plc，192.168.220.x
Arg600:192.168.220.y
Laptop:192.168.220.z
assign say 192.168.224.103 to you laptop(singe ip only) and then try pong the PLC).I dont think the ips assigned by you are part of the same subnet.May be this is not required in your case.please try this.

Assuming you are using gprs internet ，shouldnt the static IP be a public IP?.through nat/pat you will forward packets from external port mapped to port 502/plc ip.in modbus poll software you will provide static ip +external port.
My knowledge of networking is limited.My comments are purely based on working on a gprs modem few years ago.

Rahil

Hi,
After going through the ARG600 manual, I believe you will have to use a dynamic DNS service provider, to enable clients to reach the ARG600.
1)gateway mode :Network to serial slaves
2)Modbus gateway enabled
3)The default port external clients connect to is 502
4)Cellular activity LED should be blinking.Try to connect a laptop to the internet via the wireless gateway.
Good luck.it would be great if you could circle back later with a description of how you finally managed to get the system running.

5)In case network to serial slaves mode is used, I recommend connecting PLC and ARG600 via their RS-485/RS232 ports and not via ethernet i.e PLC will be a modbus serial rtu.
