Equipment Overview

The following equipment is required for using the FTP functionality:

  • FileZilla V3.28.0
  • CJ2 CPU series or equivalent controller
  1. FTP is supported in CJ Ethernet/IP Unit or built-in Ethernet/IP port with unit version 2.0 or later
  • OMRON HMC-EF*83 industrial grade Compact Flash card
It is highly recommended using the OMRON HMC-EF*83 industrial grade Compact Flash card. Consumer Compact Flash cards are less resistant against industrial environments. It may or may not function correctly.
