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.
