7 PARAMETER SETTING
7.4.3 Default assignment parameters
As the MODBUS
R
device assignment parameters, default assignment parameters are
available as initial values.
To use the default assignment parameters, Bit 1 of the communication condition
setting (switch 2) of the intelligent function module switches must be set to OFF.
Refer to Section 6.6 for details of the intelligent function module switches.
The following shows how the MODBUS
R
devices are assigned by the MODBUS
R
device assignment parameters and the default assignment parameter values set to the
QJ71MT91 buffer memory.
