WATLOW F4 CONTROLLER with TELNET communication

[testnet]

Hi  I m trying to control watlow f4 through Telnet communication.

Really new to MODBUS protocol and do not know how it works with telnet connection. Please help by providing drivers/sample labview code or ideas to control Watlow f4 through telnet communication.

Thanks,Kathir

Welcome to the LabVIEW board. There a lot of threads discussing about this. Do a search first, then start wiring and then postback if you stuck up anywhere.

All the very Best,

Hi,  I have serial port(RS232) on end which is connected to Watlow and RJ-45 another end. Which means, i have connected the Watlow to a console server. So when I need to access the watlow, I have to telnet like this "Telnet 10.20.3.11 8008"

Where 10.20.3.11 is IP of the console server, and 8008 is the port in console server where the watlow is connected.

Thanks, Kathir

It depends on their interface.  I have used the Watlow with a serial connection and with a serial to GPIB connection.  In my case, there were some slight differences,

If the serial to thernet converter being used doesn't change the ineterface, then the Modbus will work just fine.  If you are trying to use some examples, you may need to make some changes if they are using serial instead of telnet.
