Cautions for using GT15-QBUS2 and GT15-ABUS2
The stage number of communication units installed on the next stage of GT15-QBUS2 or GT15-ABUS2 are
recognized by the GOT differently depending on the extension interface position.
For communication units installed in the extension interface 2 side, even if the communication unit is physically
installed in the 2nd stage position, the GOT recognizes the position as the 1st stage.
(2) Standard size bus connection unit (GT15-QBUS and GT15-ABUS)
A bus connection unit can be installed in any position (1st to 3rd stage) of the extension interface.
