Control.com - Nerds in Control

Hi,

I have a weight controller with RS-232 protocol. This controller does not support Modbus, only RS-232. I want to transmit the data to a Modbus TCP device. How can I do this? Flow chart is like this:

Weighting->Converting analog output->To RS-232 protocol->To Modbus/TCP device

I need to achieve the last part. If it is not possible to convert directly to Modbus/TCP, I can accept that firstly a Modbus RTU than a Modbus/TCP convert.

You could use Omnii-Comm with Ethernet to do this for you.

You can use this gateway for example

If you have a computer anyway,
you can use it's serial interface and network port and do it in software.

We provide this within our project
http://pvbrowser.org

For serial communication use:

For implementing the Modbus/TCP server use:
http://pvbrowser.de/pvbrowser/sf/manual/rllib/html/classrlModb us.html

Thus you can handle any protocol that is run on RS232.

It's not clear from your desired configuration whether you want your Modbus/TCP device to actively transmit the data (i.e. act as a client) to some other Modbus TCP slave (server), or whether you want your Modbus/TCP portion to just passively sit there until a Modbus/TCP client requests the I/O data from it. Most Modbus/TCP devices are servers (the second scenario).

If that is also your scenario, then you can look at the ICC ETH-200 gateway, which supports Modbus RTU (master and slave) and Modbus/TCP (server).
