I can but it will be Tuesday before I'll be back in the office.

How about I contact you through the forum and we can arrange a time when I get back to the office?

Thanks...John

Hello All,

Noobie here and I have a question about Modbus4J.

I was using WireShark packet capture to look at the MODBUS requests being sent by Modbus4J. One of the things I noticed is that Modbus4J opens/closes a TCP connection for each MODBUS request.

Is there a way to set the Modbus4J driver to open a TCP connection once, send all the MODBUS requests, and when all the responses have been received or a timeout occurs close the TCP connection?

OR...Just leave the TCP connection open until a timeout occurs or the Modbus4J driver is shutdown.

Thanks...John

Hello All,

Noobie here.

Successfully got Mango installed and talking to a MODBUS/TCP slave reading two Input Registers. Very easy to do. My complements to the programmers.

However, when I go the Watch List screen I get the error...

 pointNames is undefined

The Watch List screen shows the two points that I created under the Data Sources but when I click on one of the tags nothing happens.

Running Mango under FF 3.6

Any ideas?

Thanks...John
