Tip
1. The data link module was designed for local stations and cannot be set as master station. For this reason,
a local station that is upgraded to Q Series cannot become the master station. Instead, one of the existing
A Series local stations should be set as the master station. The station numbers should be changed
accordingly, but the I/O address and parameters can remain the same.
2. Minimal setup is required, as network parameter settings (excluding link refresh setting) are automatically
detected by the local station data link module. FROM/TO instructions within sequence program (refresh
program) are required to enable send/receive cyclic data.
A sample program to enable send/receive of cyclic data can be created by "A/QnA -> Q conversion
support tool" (which can be downloaded from the MELFANSweb). (Refer to Section 9.2)
3. For MELSECNET(II), the station numbers must be assigned in the connecting order starting from the new
master station.
4. The QA1S51B extension base without power supply module can be used for the local station data link
module mounting base.
Note that the voltage drop must be calculated if the extension cable is long.
