PLCDesigner Safety
Programming of Safety controller c250-S is based on a certified plug-in
that is fully integrated in the PLCDesigner Development System.
Safety controller c250-S is a sub-node of the standard control unit and
provides an application, task, lists of global variables, POEs and logical
I/Os.
The integrated function diagram (FD) safety editor (to IEC 61131-3, certi-
fied for use with IEC 61508 SIL3 applications) is used for basic or extended-level programming
by means of certified function blocks (IEC 61131-3 or PLCopen Safety) as specified in the user
