Hi,

I am using the ttsims from raychem tracetek to do leak detection in industrial buildings. These are modbus devices.

I just purchased a rs485 to ethernet convertor (netbiter). I'd like to know how I can grab the data over the ethernet onto a webserver with a dynamic webpage. I would also like to have alarms send by email when an event on the modbus to ethernet network is captured.

I succeeded to connect the modbus over rs485 to the convertor and then to the network.

Thanks
Sven

 

I'm creating a project using a ModbusTCP OPC server and EasyHMI.

EasyHMI: http://www.easyhmi.com

So far so good... very nice package for the price.

Hi,

This is an interesting application and nowadays such type of applications getting more and more popular. Sunlux do have hardware module which has a processor, serial and ethernet connectivity and also has suppport for dialup, PPP etc. Webserver also can be configured in that module. Check up with http://www.sunlux-india.com or [email protected]

Hi.

As I understand it you would like to monitor the Modbus devices from a web page at a central location (like a PC).

Is Modbus TCP mandatory for you?

I see that you are using a product in the NetBiter family. There is a new product that connects to Modbus devices and then puts the Modbus registers in an embedded web server inside the Gateway. You can configure what Modbus registers you would like to montitor (read) or control (write) through onboard webpages.

Basically you can use an Ethernet/Internet connected computer at your central location and browse the Modbus devices in the Gateway. Modbus TCP would not be used... or am I wrong?

This is the product I belive would do the job: http://www.intellicom.se/eg_webscada_modbus.shtml?17

I'm using a FC2400 device to do this.

The modbus data is monitored and interesting data is displayed on a webpage. Device includes internal webserver.

You can define events and link with actions, like email.
