It is possible to use the RLPASET instruction to set the network parameters and start
the data link.
Using the RLPASET instruction to set the parameters has the following advantages:
• It is possible to mount five or more QJ61BT11 modules (see Section 2.2.1 for details
about the number of CPUs that can be mounted).
• It is possible to change the network parameter settings while the PLC CPU is
running.
POINT
It is recommended to use GX Developer to set the parameters when the number of
QJ61BT11 mounted is 4 or less.

(1) Setting method
For more details on the setting, see Section 6.4.
For the RLPASET instruction, see Appendix 2.7.
(2) Precautions when using the RLPASET instruction to set the
network parameters
(a) The remote I/O net mode cannot be used.
The module operates in remote net mode.
(b) If it is necessary to change the network parameters while the PLC CPU is
running and the data link is being performed, the data link should be
stopped once using SB0002 (data link stop).
