Specification Range - Mitsubishi Electric MELSEC iQ-R Series User Manual

Specification range

All the link devices of the network module can be specified. The link devices which fall outside the range specified with
"Refresh Setting" can also be specified.
For the following modules, specify the "Extended Mode (iQ-R Series Mode)" in the "Link Direct Device Setting" of the CPU
parameter. (Default setting is "Q Series Compatible Mode".)
• CC-Link IE Controller Network-equipped module to which the link points extension is set.
[CPU Parameter]  [Memory/Device Setting]  [Link Direct Device Setting]
Window
When the network module to be administered contains any of the following modules when specifying the link
direct device, set the "Extended Mode (iQ-R Series Mode)" to the "Link Direct Device Setting".
• CC-Link IE Controller Network-equipped module to which the link points extension is set.
Other modules operate in the both mode.
*1 Before using, check the versions of the CPU module and engineering tool used. ( Page 747 Added and Enhanced Functions)
*2 Applies when the "Link points extended setting" of the module parameter is set to "Extend" and the extended link device is specified.

Specification range for writing
Writing should be done in the range which is within the link device range specified as a send range of network parameters,
and outside the range specified as the refresh range for "Refresh Setting".
Note that writing in the range specified as the refresh range overwrites link device data of the network module during refresh
process. When writing data to a writing range of another station using the link direct device, data is overwritten with received
data during data reception from another station.

*1 There is only one network module to which the link direct device can write data for each network number. When more than one network
module with the same network number is mounted, the network module with the lowest slot number is the target for writing by the link
direct device.
Specification range for reading
Data can be read from the entire range of link devices of the network module.
*1 There is only one network module for which reading is allowed with the link direct device for each network number. When more than one
network module with the same network number is mounted, the network module with the lowest slot number is the target for reading by
the link direct device.
