APPENDICES
(2) Precautions
(a) With combination of Ethernet module and MELSECNET/10, maximum 7 relays
can be performed.
(b) The following shows other station access with or without setting for other station
access:
• When other station access valid module is set, the set module is used for
relay.
• When other station access valid module is not set, the relay is as follows:
When MELSECNET/10 is available: 1st of MELSECNET/10 is relayed.
When MELSECNET/10 is not available: 1st of Ethernet is relayed.
(c) When parameters are not registered in the Ethernet module, the QnACPU stores
the default parameters in all AJ71QE71.
When multiple Ethernet modules are installed, settings are made in the order of
1st station and 2nd station and so on counting from the QnACPU side.
