(4) Precautions when using the G(P).RLPASET instruction to set the
9 - 44
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 programmable
controller CPU is running and the data link is being performed, the data link
should be stopped once using SB0002 (data link stop).
(c) It is necessary to set I/O assignments for modules whose network
parameters are set by the G(P).RLPASET instruction.
In addition, do not use GX Works2 to set the network parameters and
automatic refresh parameters for modules whose network parameters are
set by the G(P).RLPASET instruction.
If the G(P).RLPASET instruction is used to set network parameters for
modules whose network parameters and automatic refresh parameters
have been set by GX Works2, the G(P).RLPASET instruction will complete
with an error and the network parameter settings performed by the
G(P).RLPASET instruction become invalid.
(d) If the switch setting of an intelligent functional module for which an I/O
assignment is set, has not been performed or is wrong, the G(P).RLPASET
instruction completes with an error.
However, the L series master/local module with the smallest head I/O
number seen from the programmable controller CPU starts CC-Link
automatically.
(e) Do not use GX Works2 for setting the network parameters, if the network
parameters of all the modules are set by the G(P).RLPASET instruction.
Change the "Number of Modules" setting to blank if the network parameters
have been already set by GX Works2.
Moreover, in case a system includes both a module for which the network
parameters are set by GX Works2 and a module for which the network
parameters are set by the G(P).RLPASET instruction, the module for which
the network parameters are set by the G(P).RLPASET instruction should
not be included in the "Number of Modules" setting of GX Works2.
(f) After executing the G(P).RLPASET instruction, turn on SB0003 (refresh
instruction) to refresh cyclic data.
(g) Automatic refresh is not performed.
The devices should be refreshed via the FROM/TO instruction or the G device.
(h) It is not possible to set input status from a data link faulty station.
Inputs from a data link faulty station are cleared.
(i) The standby master function is not available.
