How much? I have my modbus server turn off.

Im not responding.

I'm using TCP.

How can I avoid this error?

I start Mango with a Modbus IP data source created and get this error in the standar output:

What can be happening? There is now modbus server to connect.

I'm a little confuse about terminology.

In non ip modbus, we have master and slaves. Master ask and the slave answer.

In modbus ip, we have clients and servers. A client is like a master? A server can manage many slaves?

How does mango works when having a modbus ip data source? As a client?

Thanks,

Seems I cant capture traffic in the loopbak interface http://wiki.wireshark.org/CaptureSetup/Loopback

Is there a way to test if Mango is sendign the modbus ip pabkets over the net?

Tried it, but same result: none.

In the Python script I dont see any request from Mango. I did see it while using the "Search for nodes" feature.

I've created a modbus IP data source and data point.
I'm also running this server in localhost:502 http://code.google.com/p/modbus-tk/source/browse/trunk/examples/tcpslave_example.py

If I use th scan nodes feature, Mango successfully finds the single slave in the server. But if I create a Data point for the slave 1 no data is recorded in Mango and no output appears in the server stdout.

Am I missing something? This is supposed to work.

I have connection to the DB!

I'm using this statement:

But seems not to work. I get an error refearing an excesive package size.

If I use this statement:

I do get a value.

As explained in the on line doc, id is a row id, ea1 a value and timestamp the time the value was recorded.

Thanks,

I'm having problems with the Connection string parameter. Could you provide an exmaple of it? It's not clear in the on line docs.

Could you giveme an example of how to get the data from a MySQL data base?

Excellent. How can I contribute my translation later?

When you finally have to login you're using a hidden field and that's good. Any way, not having a hidden field when creating the account is a problem: some one can see over your shoulder and remeber your password. Is a security risk.

I have some machines using a modified modbus to comunicate with a server. The server has all the information and save points in a data base.

How can I connect it with Mango?

An idea is to make my server talk IP Modbus in a new port and connect Mango to it using a Data Source.

Other idea is create my own Data Source type and talk to the server in this language.

Which one is a better approach? Other ideas?

Thanks
