Title: Connection to multiple devices on Modbus TCP/IP
Post by: qwideman on August 07, 2013, 05:35:17 PM

I don't know very much VB at all. What would be required to make it possible to connect multiple Modbus Devices over Modbus TCP/IP? For example, having 2 pilot lamps addressed to separate PLCs.

Could a module be made that would support this?

I don't think I can write that code.  ;D


Thank you,

You can add multiple driver instances to the form and give each one a unique IP address. In your control (e.g. pilot light), set the ComComponent property to the driver instance you want it to get the data from.

Thank you, I had done that, but I see now that my one device is offline.
I'll give it another shot once it comes back on.
