10.3.10 Station No. setting for MELSEC data link functions
The following indicates the station numbers set for the MELSEC data link functions.
* 1
* 2
* 3 For CC-Link communication, station No.64 cannot be specified.
When its own station No. is 64, the other station cannot be specified. (Access is allowed only to the own station.)

<Logical Sta. No. setting method>
Set "0" in the upper byte (network No.) of the above format, and specify a logical station No. in the
lower byte (station No.).
The setting range of logical station No. is 65(41
H) to 239(EFH).
Set the logical station No. on the <<Target setting>> tab of the MELSECNET/H utility.

<Logical station No. setting method>
Set "0" in the upper byte (network No.) of the one shown left, and
specify the logical station No. in the lower byte (station No.).
The setting range of logical station No. is 65(41
H) to 239(EFH).
Set the logical station No. on the <<Target setting>> tab of the
CC-Link utility.
