Reserved Station Function - Mitsubishi Electric L26CPU-BT User Manual

8.3.4

Reserved station function

This function prevents device stations that are not actually connected (but to be connected in the future) from being
treated as "data link faulty stations" by the master station and local stations.
When the master station is placed in the remote net ver.2 mode, points for reserved stations can be set to 0.
Use GX Works2 to set 0 points for reserved stations.
Although dedicated instructions are not usable for this setting, if reading from or writing to reserved stations is disabled
when refreshing cyclic data with FROM/TO instructions, the same result is obtained.
Master station
If a connected device station is specified as a reserved station, data link with the specified device station becomes disabled.
[Setting method]
Set the reserved function in "Station Information Setting" of the network parameter setting in GX Works2.
(Refer to Page 83, Section 7.3.2 (2).)
• Make reserved station setting by choosing "Station Information Setting" - "Reserve/Invalid Station Select".
• Make 0 points setting for the reserved station by choosing "Station Information Setting" - "Remote Station
Points".
