Pre-defined CFC Charts
One CFC chart is already installed when the SIPROTEC 4 device is delivered.
Device and System Logic
An event-controlled logic operation is implemented with blocks of the slow logic (PLC1_BEARB = slow PLC
processing). In doing so, the binary input ">Data Stop" is modified from a single point indication (SP) into an
internal single point indication (IntSP) by means of a negator block.
