Setting Communication Specifications (Ethernet - PLC Link)

Communication specifications such as link areas or communication speed and data length are set.
Setting Communication Specifications (RS-232C/422 - PLC Link)
Important
  • Before setting the communication specifications, set the "Serial (Ethernet)" communication module to "PLC link (SYSMAC CS/CJ/CP/One)" (or to "PLC link (MELSEC Q series)" (FZ3-9IconIcon/H9IconIcon only) in the case of a PLC by Mitsubishi Electric Corporation), save the setting, and then restart the system. When the system is restarted, the communication settings are initialized.
    Setting the Start-up Status [Startup Setting]
  • Use the same communication specification settings for the controller and the external device.
  • When making system settings/Ethernet settings, do not send external input into the Ethernet.
  1. On the Main screen, tap the [System] menu - [Communication] - [Serial] - [Ethernet].
    The Ethernet window is displayed.
  2. In the communication setting area, set the following items.
