Appendix 2 Differences between the QJ71LP21/QJ71LP21-25/QJ71BR11 and the
AJ71LP21/AJ71QBR11, A1SJ71QLP21/A1SJ71QBR11
Appendix 2.1 Differences in LED displays and switch settings
The MELSECNET/H network modules QJ71LP21, QJ71LP21-25 and QJ71BR11 have
the same LED displays and switch settings as those of the MELSECNET/10 network
modules AJ71QLP21, AJ71QBR11, A1SJ71QLP21 and A1SJ71QBR11. However,
each network module has the following differences from others as shown in the table
below. Please consider these differences when operating the network modules.
