Extension cable
*1: QA1S51B is an extension base that does not require a power supply, so if the extension cable is long, a voltage drop could
prevent the specified voltage from being supplied. Always calculate the voltage drop.
*2: QA1S51B only has an IN type extension connector, so it will be the extension final stage. QA6 B (Large Type) extension base
cannot be connected below QA1S51B.

Tip
1. Except for the local station replaced with the Q Series, modification to the system configuration and
programs are not required.
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. If slots are left empty in the replacement Q Series CPU after connecting the A (Large Type) extension
base onto which the QA6B extension base unit or QA conversion adapter QA6ADP is connected, the
MELSECNET(II), /B local station data link module can be connected using the A-A1S conversion adapter.
QA1S6B or QA1S51B do not need to be additionally selected in this case.
