Device specification with labels/comments
A device can be specified with a label or a comment by importing global labels (including module labels) set with an
engineering tool to a project of the configuration tool.
For details on importing labels, refer to the following manual.
MELSEC iQ-R High Speed Data Logger Module User's Manual(Application)
Access units
The following table shows the number of device points (access units) that can be accessed in a single process when sampling
the device values in the CPU module.
When the number of sampling device points are lower than the access units, the device values of the same sequence scan
are sampled.
Since device values are sampled over multiple sequence scans when the number of sampling device points exceed the
access units, data inconsistency (old data and new data overlap) may occur.
To prevent data inconsistency, set the number of devices sampled at one time to less than the access units, or use high speed
sampling.
*1 When accessing from other than the Ethernet port of a high speed data logger module
*2 When accessing from the Ethernet port of a high speed data logger module
*3 When "Own station" is selected in the [Station specification] tab of the access target CPU setting.
*4 When "CC-Link Module" or "Serial Communication Module" is selected for the module type of the access source system under the
[Network route] tab of the access target CPU setting, and "Use the co-existence network route" is unselected.
*5 When accessing long counter
*6 When accessing long timer and long retentive timer
*7 Indicates Q00JCPU, Q00CPU, and Q01CPU
*8 To prevent data inconsistency, use the MELSEC data link functions such as mdSendEx to write devices of the C Controller.
