Easy data sharing with third-party programmable controllers without programs

  • Communication without a program
  • The Ethernet interface module allows device data exchange by parameter registration with Mitsubishi Electric programmable controllers as well as third-party programmable controllers (simple CPU communication function)*1
  • Data collection is easier without changing programs of the existing programmable controllers

Easy data sharing with third-party programmable controllers without programs

*2.Supported by the embedded Ethernet port only.

Dual Ethernet ports support two networks

  • Multiple network compatibility
  • Equipped with two Ethernet ports, the module enables Ethernet, CC-Link IE Controller Network, and CC-Link IE Field Network communications. Different networks can be simultaneously connected to the two Ethernet ports

Dual Ethernet ports support two networks

Access to third-party devices' information (memory area)

  • Communication without a program
  • Simple device communication function enables communication not only with Mitsubishi Electric devices but also with third-party devices (robots, temperature controllers, etc.) to obtain various information such as operation and diagnostic information
  • Reads/writes necessary data in the target device by simply selecting a command. This is useful when accessing the proprietary data in a specific device
