(2) Accessibility list
The following table indicates whether access can be made or not.
The connected station CPUs are all accessible.
Whether the relay target CPU is accessible or not is indicated by
(accessible)
or
(inaccessible).
POINT
When using the Q series-compatible E71 or QE71 (when UDP/IP is used), you must
set the Ethernet parameters in GX Developer parameter setting.

*1
: Accessible to the A171SHCPU, A172SHCPU, A173UHCPU(-S1) or A273UHCPU(-S3) only.
*2: Relayed stations cannot be accessed through the QSCPU.
*3
: Inaccessible to Q12DCCPU-V and QSCPU relayed by CC-Link IE Field Network since CC-Link IE Field Network is not supported.
*4
: On the connected station side (Q series-compatible E71), always specify the station number set in the Ethernet parameter.
*5
: Set the parameter-set values of the target station side Q series-compatible E71 or QE71 to the network number and station number.
Also set the "Station No.
IP information" of the Q series-compatible E71 or QE71 parameter setting.
At that time, specify any of the IP address calculation system, table conversion system and combined system as the "Station No.
IP
information system".
*6: The Redundant CPU is inaccessible to the computer link module which is on the main base.
*7: Inaccessible to LCPU relayed by CC-Link IE Controller Network since CC-Link IE Controller Network is not supported.
