Gateway Set
(Q6KT-NETGW-□□)
■Use a Q2AS based MELSECNET(Ⅱ)/10 gateway to gradually convert MELSECNET(Ⅱ)
stations to MELSECNET/10. MELSECNET/10 is backwards compatible with
Q Series via MELSECNET/H.

■Replace AnS/QnAS Series MELSECNET(Ⅱ), MELSECNET/B stations with Q Series systems.
The MELSECNET(Ⅱ)/B local station data link modules allow a Q Series system to directly connect to existing
NET(Ⅱ)/NET/B data link system via a QA1S□B extension base unit.


Supported CPUs
High Performance Model QCPUs [Q02(H), Q06H, Q12H, and Q25HCPU] and Universal Model QCPUs
whose first five digits of the serial number are 13102 or later.

Compatible extension base units
QA1S□B or QA□B with A-A1S module conversion adapter (A1ADP-SP)

Number of modules per CPU
Send point range can be further increased by mounting up to 6 modules per CPU.

Network parameters
Minimal setup required, as network parameters settings are automatically detected by the module.

Link refresh setting
Link refresh setting is not automatically detected. Hence, FROM/TO instructions within sequence program to
enable send/receive cyclic data are required.
Sample programs for link refresh are provided in "A/QnA
-
> Q Conversion Support Tool". The sample
program can be used to create a QCPU program which may reduce development time.
For details, please contact your local Mitsubishi sales office or representative.
