8.2 Basic Operation
■
SFC (Sequence Function Chart) is one of the programming languages defined in the
IEC1131-3 Standard and it is also one kind of the diagram editing mode. However, the
whole structure of SFC diagram looks like a flow chart. In fact, it is to utilize the Step Relay
S within the ELC. The number of every Step Relay S is to serve as a step point, which is
equivalent to each procedure of the flow chart. After current procedures are completed,
move on to the next procedure (which is the next step point S) requested according to the
preset terms, in this case, users can simply follow the procedure repeatedly to obtain the
best results that users need.
