Technical support / Nano as client LabView as server
« on: February 15, 2012, 01:35:24 PM »
Dear all
We are trying to run an application where Nano will be a client and a PC/Labview will be a server under TCP/IP MOBDUS protocole.

We are facing the following situation:
Nano adress the right frames at the PC (adresss:502) and the PC reads them OK. PC return is right adress of the Nano but a un-expected port number (57266). Our understanding is that this is the port used by the Nano to send the data and it becomes also the port towards which the PC want to send the respond frame. This port is not 502 but this may be OK as Nano is client ?
How can we read the 57266 port ?
Regards
Thietrry

According to some tests we have observed that only input#1 to imput#8 are refreshed during scaning, all other input#N (N>9) being unchanged.

Will you confirm that please ?

Thnak you in advance.

Thank you for your quick answer that make us to understand !


One more question :

I/O are refresh everyscan with physical value. What about the I/O not related to a physical I/O ? Do they remain in the same state ?

Hi

We are not sure that we have well understood the mapping adress syntax with Nano 10

Here is our problem :

We want to write a 1 in input#1 using Modbus TCPIP protocol.

For that we intent to use MB function 05 (Force I/O bit). Then we need to specify the adress : 0x9C41 (for 40001 Is that right ?) and the value OxFF00.

How can we be sure that bit 1 only of Input [1] will modify ? How about to modify input#2 ?

Thank you in advance for your help/support

Thierry
