LadderComOp 2.1

This application is required for PLC ladder transfer via USB or Ethernet.
When a V8 series is connected to the CPU port of a PLC, debugging has to be carried out by disconnecting and reconnecting two cables alternately: the cable that connects the PC to the PLC and the cable that connects the V8 series and the PLC.
However, using the ladder transfer function makes it possible to write the ladder program via the V8 unit and monitor the PLC without disconnecting and reconnecting the cables.
