PLC (Programmable Logic Controller) Function

GRT100 is provided with a PLC function allowing user-configurable sequence logics on binary
signals. The sequence logics with timers, flip-flops, AND, OR, NOT logics, etc. can be produced
by using the PC software "PLC editor tool" and linked to signals corresponding to relay elements
or binary circuits.
Configurable binary inputs, binary outputs and LEDs, and the initiation trigger of 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 editor tool. For PLC editor tool,
refer to PLC TOOL instruction manual.
