Precautions for using a MELSECNET/H communication unit, CC-Link IE Controller Network communication unit, CC-Link IE Field Network communication unit, CC-Link communication unit (GT15-J61BT13)

The installed stage number of communication units installed on the next stage of MELSECNET/H communication unit, CC-Link IE Controller Network communication unit, CC-Link IE Field Network communication unit, or CC-Link communication unit 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.
