Hello, i'm Rosnel Martínez from Venezuela.

I'm trying to test the Modbus protocol, and when I connect a device and configure the "socket" for input and output module "trasports" failed to establish communication. I do this and then run a "Data Acquisition" module "modbus" using the TCP / IP using the "socket" previously configured.

The error says "Operation in progress" and not allow the connection or establñecer the test of "Data Acquisition".

Annex a picture of the error and socket configuration.

Can you help me?

2 Rosnel,

see http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

set default port number is 502 (for Modbus TCP/UDP)

Thanks for the quick response.

you're right, I'm wrong in writing.

Testing with the 10,002 port which is open and the error still persists. Annex image error and the Data Acquisition module

And I'm sure that the device supports Modbus because the test is to make the comparison with LabView for Data Acquisition

Hi. Your question is very poor, so it is impossible to understand your problem... Try to explain it more detailed and with screen shots may be.

In the documentation to this device the supports of ModBus is declared, so it can be connected to OpenSCADA. For more information read http://wiki.oscada.org/HomePageEn/Doc/QuickStart and http://wiki.oscada.org/HomePageEn/Doc/ModBus .
