SDO for data read/write with node guarding and set operational
In this engineering example for data write and read via SDOs, a trigger can be set automatically when changing a value
to be transmitted, or manually via the first line of the operating page. Function block CPREAD, which is used normally
for reading PDOs can be used to realize node guarding for an adjustable node. Moreover, this block ensures that the se-
lected node is set “operational”. In this case, connecting the “valid” output on the AND gates may be purposeful to
prevent triggering as long as the connected instrument is not ready for addressing.
