PRE-OPERATIONAL PROCEDURES AND SETTING
6 - 3
1: If parameters are set at the GX Configurator-MB, power OFF and then ON or
reset the programmable controller CPU with the CPU RUN/STOP switch set at
RUN.
IMPORTANT
(1) When setting parameters, do not write any data to the "System area (use
prohibited)" among the QJ71MT91 buffer memory addresses.
Doing so may cause malfunction of the programmable controller system.
(2) When making any parameter setting request, or other parameters, do not output
(turn ON) the "Use prohibited" signal among the output signals.
Doing so may cause malfunction of the programmable controller system.
(3) When having replaced the QJ71MT91, reset the other device of communication
target.
If the device holds the Ethernet address of the communication target,
communication may not be continued since the Ethernet address is changed by
the replacement of the QJ71MT91.
Similarly, after replacing the target device (such as a personal computer), reset
the basic parameter setting of the QJ71MT91 or restart the QJ71MT91.
POINT
(1) Use GX Developer to make I/O assignment and intelligent function module
switch setting.
Use GX Configurator-MB or sequence programs to set the basic parameters
(refer to Section 7.2), automatic communication parameters (refer to Section
7.3), or other parameters of the QJ71MT91.
(2) To update the parameter settings added/changed on GX Developer, write the
parameters to the programmable controller CPU, and then reset the
programmable controller CPU.
