Note 2: It is possible to change the following items set by the Datalink Wizard for each node:
(2) PLC type, (3) Area (memory area and start address), (4) Send size, (5) Node refresh
sequence (see note 3), and (6) Status area.
Note 3:
The node refresh sequence is set using F4: Move Up Area and F5: Move Down Area.
Reference:
The operations differ for Controller Link and SYSMAC LINK when creating data links.
The following table shows the points on which the manually set data link functions are
different.
Function Controller Link SYSMAC LINK
(1) Offset setting Supported Not supported
(2) Receive size setting Supported Not supported. (It is only possible
to specify whether all of none of
the data sent is to be received.)
(3) Memory area Area 1: Can be selected.
Area 2: Can be selected.
(CIO, LR, DM, EM, etc.,
according to PLC type)
Area 1: CIO
Area 2: DM
(Fixed.)
(4) Communications cycle time
setting
Not supported Supported
These four differences apply even to data link setup operations using the CX-Net. Aside from these points, other
operations are basically the same.
