QJ71DN91
If communication with the
slave node fails due to
incorrect parameter setting,
the message group is
automatically switched and
communications can be
established.
Default value: 200ms
Precautions when replacing the AJ71DN91/A1SJ71DN91 with
Check the QJ71DN91 status with MS, NS, and ERR. LEDs.
This LED is added to the QJ71DN91.
Set the host node number of the QJ71DN91 with node number
switches (see Section 5.3.2).
The node number of the AJ71DN91/A1SJ71DN91 can be
checked using the following:
• Buffer memory (address: 01D4
• SyCon
Set the baud rate of the QJ71DN91 with the mode switch. (See
Section 5.3.3.)
The baud rate of the AJ71DN91/A1SJ71DN91 can be checked
using the following:
• Buffer memory (address: 01D5
• SyCon
Set the parameters of the QJ71DN91 to the buffer memory via
the QCPU. Set them by the following methods.
• Sequence program (See Section 7.3.2 and Section 8.2.2.)
• GX Configurator-DN or GX Configurator2-DN (See Section
7.3.1 and Section 8.2.1.)
