5 - 38
This parameter is used to specify any of the following modules to be relayed when a
data communication request for which the network number of the access target
programmable controller station cannot be specified from the host (access from the
serial communication module (A compatible 1C frame), the Ethernet module (A
compatible 1E frame), etc. to other stations) is issued.
• CC-Link IE controller network, MELSECNET/H, MELSECNET/10 module
• Ethernet module
This setting is not required when a data communication request for which the network
number can be specified, such as the serial communication module (QnA compatible
3C frame, QnA compatible 4C frame) or Ethernet module (QnA compatible 3E frame),
is used. Leave it as the default (1) setting.
For details of the serial communication module or Ethernet module protocol, refer to
the Q Corresponding MELSEC Communication Protocol Reference Manual.
