PARAMETER SETTING
7.3.1 MODBUS(R) device assignment to the programmable controller CPU
device memory
(1) MODBUS device size
The MODBUS devices available for the QJ71MB91 are shown below.
* 1 The availability of Extended file register read/write depends on that of the file register (ZR) read/
write to the programmable controller CPU.
For example, if the file register (ZR) is stored on a Flash card, the extended file register is read only
because the file register (ZR) is read only.
User's Manual (Function Explanation, Program Fundamentals) for the CPU module used
* 2 The maximum access points and maximum file number of the extended file register depend on the
file register (ZR) assignment size of the programmable controller CPU.

Remark
Refer to the following for assignment of the extended file register and the
programmable controller CPU file register (ZR).
