■The extended mode is selected for the station type.
The following shows the calculation formula when the extended mode is selected for the station type of a CC-Link IE
Controller Network module.
Comparison between
LT and LS
LT > LS
LT < LS
When the CPU module on a relay station transfers link devices to other network by using the interlink
transmission function among multiple network systems, the transfer processing time of the CPU module on
the relay station affects the transmission delay time. For more details, refer to the following manual.
