5 BASIC OPERATIONS
5.4.5 Changing the connection station
The network configuration information of GX Explorer displays the network information
based on the connection station.
Hence, when you change the connection station, the already acquired network
configuration information becomes different from the actual network configuration
information, disabling communications with the specified station.
At the time of the connection station check, GX Explorer checks the match between
the network configuration information already acquired and the network configuration
information based on the information of the new connection station.
The following are the operations to be performed for match and mismatch.
(1) When match occurs
When you changed the connection station to the other station displayed in the
network configuration information, the network configuration information of the
new connection station matches the already acquired network configuration
information, and the station corresponding to the new connection station is
recognized from the already acquired network configuration information.
<When match occurs at connection station check>
When you did not change the network configuration, choose the Yes button.
The already acquired network configuration information is replaced by the
network configuration information based on the new connection station.
To replace the network configuration information takes shorter time than to
acquire the network configuration information again.
POINT
• When the connection station is changed from the QCPU (Q mode) to the
QnACPU, the QCPU (Q mode), QCPU (A mode) and ACPU are not displayed.
• When the connection station is changed from the QCPU (Q mode) to the QCPU
(A mode) or ACPU, the QCPU (Q mode) and QnACPU are not displayed.
• When the connection station is changed to any of the local stations in the same
configuration that consists of only CC-Link local stations, the new connection
station may not be recognized.
(Since the CC-Link local stations in the same configuration cannot be identified
between each other)
• When the connection station is changed to the ACPU other than the AnUCPU,
MELSECNET/10 is recognized as MELSECNET/II, resulting in network
configuration information mismatch.
