(2) Communication condition setting (Switch 2)
Specify the starting methods, the send frame, and the online change
enable/disable setting.
1: The information in this area is ignored.
However, if the setting in this area is other than 0, a switch 2 error (error code: 7302
occurs.
If the switch error has occurred, correct the switch setting and then switch the power
OFF then ON or reset the programmable controller CPU.
2: When setting parameters by GX Configurator-MB, set 1 to both b0 and b1.
(a) Basic parameter starting method (Bit 0)
Set the basic parameters for the time when the power is turned ON from
OFF.
[When corresponding bit is OFF]
The QJ71MT91 starts up with its default basic parameters, and starts
communication.
[When corresponding bit is ON]
The QJ71MT91 starts up with the basic parameters set using a sequence
program or GX Configurator-MB, and starts communication.
However, the user-set basic parameters are not registered to the
QJ71MT91 until the following operation is performed.
When a sequence program was used to set the basic parameters
Turn ON "Basic parameter setting request (Y1)".
When GX Configurator-MB was used to set the basic parameters
After the intelligent function module parameters have been written to the
programmable controller CPU, the initial setting is updated when the
programmable controller is powered ON from OFF or the programmable
controller CPU is reset (with the programmable controller CPU's
RUN/STOP switch set to RUN).
POINT
(1) Make this setting ON when a sequence program or GX Configurator-MB is used
to set the basic parameters.
(2) If no basic parameters have been set with this setting ON, the master function,
slave function and GX Developer connection function do not operate.
Refer to Section 6.6.1 for details of the communication starting conditions of this
switch setting and each function.
