Programming Example, FP-FNS Block DeviceNet
Produced data represents data that will be sent to the master. Thus, from the slave's
point-of-view, it has to be regarded as output data.
Consumed data represents data received from the master. Thus, from the slave's
point-of-view, it has to be regarded as input data.
Global Variable List
To use the DUTs for further programming and to pass on the process data to an application
program declare the following global variable with the type of DUT that was created in the
previous step. The global variables are afterwards accessed by the variable class
VAR_EXTERNAL in the example program's header.
POU Header
In the POU header, all variables that are required for the program are declared. The size of the
variables ConfigIn and ConfigOut must correspond to the number of entries in the DUTs input
and output.
