3.2.4 PLC (Programmable Logic Controller) Function
GRL150 is provided with a PLC function allowing user-configurable sequence logics on binary
signals. The sequence logics with timers, flip-flops, AND, OR, XOR, NOT logics, etc. can be
produced by using the PC software "PLC tool" and linked to signals corresponding to relay
elements or binary circuits.
Configurable binary inputs and binary outputs, and the initiation trigger of fault record and
disturbance record are programmed by the PLC function. Temporary signals are provided for
complicated logics or for using a user-configured signal in many logic sequences.
PLC logic is assigned to protection signals by using the PLC tool. For PLC tool, refer to PLC tool
instruction manual.
