Ethernet/IP I/O data

[Ben_Engelen]

I was testing with Ethernet/IP communications, plan is to use I/O data communications.

But i have a problem regarding Data type to be use.

The VI"s : "EthernetIP Get Assembly Instance Data VI" and "EthernetIP Set Assembly Instance Data VI" have an input/outupt terminal for Data and it is an U8 array.

The help states to use the un/flatten to string functions, but this is not possible.

"Because the data is written as a raw bytestream, you must convert the data to the correct data type. In LabVIEW, use the Flatten To String function to convert the data to a specific data type. Note that you must specify little-endian byte order." 

Does anyone have an example available?

I have another question, can anybody give an idea on the communication speed possible using Messaging and I/O data, target is an Allen Bradley PLC.

Thanks,

Ben Engelen

Hello,

what do you mean with thatit's impossible to use flatten/unflatten to string functions?

The following way should work:
