With function block GT (from GET) you can poll a 32-bit value from the
easyNet network . The easyNet network is referred to as NET below. GET
function block GT automatically fetches the data designated for itself as soon
as it is provided on the NET by another NET station using PUT function block
PT.
easy800 device allows the use of up to 32 GT function blocks.
EASY802-DC-SWD is not provided for the function block.
Contacts and Coils
A closed contact indicates for the duration of a processing cycle that new
data was received via the NET and is present at the function block output

Number of the sending station
The NET can connect up to 8 stations that can exchange data with each
other. The stations are identified by their station number. Further information
on the easyNET network is provided in ￫ Chapter 6, "The network
Net" from Page 273.
Number of the send function block
The sending station has 32 function blocks for transmitting 32-bit values to
the network.
