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.
